The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response. dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage. Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun. Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal. Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue. dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues. Ticket splitting: 11-way ticket split from last month has voted (transaction). Ethereum support in atomicswap is progressing and welcomes more eyeballs. decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page. decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here. Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)
Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s. F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%. Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak). Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1. Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).
Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target. Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.com – translated, also on asicminervalue) dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.
Changenow announced the option to buy DCR with fiat.
TokenPride: "We are seeking feedback on the general setup of our payment processor. We have tried to make it simple and user friendly. 10% of all purchases made in Decred will be donated to the Decred Development fund - and we will be releasing original Decred designs in the future".
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project). The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below. Arbitrade is now mining Decred.
Campus Party in Brasilia, Brazil. @girino, @Rhama and @matheusd talked about Decred. Matheus was interviewed by a TV channel. Check this quick report about the event, click "Show newer" to continue reading. (photos: 123)
Blockchain Summit in London, UK. This was not a full blown presence with stand but rather investigation of opportunities by @kyle and @Ani. The resulting detailed report is a good example of a document advising to stakeholders whether it is worth spending project funds.
Meetup in Berlin, Germany on July 18. @jz will give a talk and Q&A about Decred and chat with Ele from @oscoin about incentivizing developers. Hosted by BlueYard Capital.
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
Decred Assembly - Ep20 - Governance: Driving the Future (youtube) @cburniske and @traceagain discuss the importance of governance protocols being foundational and problems with delegated proof of stake
"I think that developers in the future are going to base their decision on where to build on the basis of governance and community. And so I look for good governance mechanisms and strong communities in blockchains." (@decredproject)

What makes Decred different and better from other cryptocurrencies? (cxihub.com)
Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository. An update on our communication systems:
Matrix chat logs are nowviewable on the web with the exception of some channels that are not bridged. The new web logs means our chats are now fully public and indexed by search engines.
Slack had an outage on Jun 27 that disturbed communications for a few hours, discussions continued on Decred's bridged platforms.
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS. A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people. A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred. "Against community governance" article was discussed on Reddit and #governance. "The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here. Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms. Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.
DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market. In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss. Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance". Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case. Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too?

About This Issue
This is the third issue of Decred Journal after April and May. Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research. The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue. As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations. Credits (Slack names, alphabetical order): bee and Richard-Red. Special thanks to @Haon for bringing May 2018 issue to medium.
Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures. dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd. Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome. Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules. Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd. dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets. Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue) Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing. Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged. Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing. A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning. Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store. iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.". Nearest goal is to make the app crash free. Both mobile apps received new design themes. dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.". Up next is supporting dynamic page widths site wide and deploying new visual blocks home page. Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One). Ticket splitting: updated to use Go modules and added simnet support, several fixes. docs: beginner's guide overhaul, multiple fixes and cleanups. decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet. @Richard-Red is building a curated list of Decred-related GitHub repositories. Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus! Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)
Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate. Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply. Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.
Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example. A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1. Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks. Three more wallets integrated Decred in September:
Atomic desktop wallet added Decred in version 0.1.31. The team answered many questions on Reddit.
AnyBit wallet added Decred. It features built-in price and news tracking. Notably, the source code is open for their Android and iOS wallets.
Coboadded Decred support into their Android and iOS wallets.
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets. Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.
The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.
Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed. Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate.

Decentralized autonomous funding of blockchain projects by @Richard-Red (medium, discussion on decred and dashpay)
The trouble with infrastructure, "thin" protocols in particular, is that someone has to build them at a cost. e.g. LN takes a ton of work, doesn't necessarily generate value itself, but it magnifies the value of BTC or whatever coin that uses it. I see the DEX in a similar light - whoever creates it is not going to make a bunch of money from it, but it will magnify the value of the underlying asset(s) that end up having a deep order book on the DEX. (@jy-p in #dex)
Twitter: why decentralized governance and funding are necessary for network survival and the power of controlling the narrative; learning about governance more broadly by watching its evolution in cryptocurrency space, importance of community consensus and communications infrastructure. Reddit: yet another strong pitch by @solar; question about buyer protections; dcrtime internals; a proposal to sponsor hoodies in the University of Cape Town; Lightning Network support for altcoins. Chats: skills to operate a stakepool; voting details: 2 of 3 votes can approve a block, what votes really approve are regular tx, etc; scriptless script atomic swaps using Schnorr adaptor signatures; dev dashboard, choosing work, people do best when working on what interests them most; opportunities for governments and enterprise for anchoring legal data to blockchain; terminology: DAO vs DAE; human-friendly payments, sharing xpub vs payment protocols; funding btcsuite development; Politeia vote types: approval vote, sentiment vote and a defund vote, also linking proposals and financial statements; algo trading and programming languages (yes, on #trading!); alternative implementation, C/C++/Go/Rust; HFTs, algo trading, fake volume and slippage; offline wallets, usb/write-only media/optical scanners vs auditing traffic between dcrd and dcrwallet; Proof of Activity did not inspire Decred but spurred Decred to get moving, Wikipedia page hurdles; how stakeholders could veto blocks; how many votes are needed to approve a proposal; why Decrediton uses Electron; CVE-2018-17144 and over-dependence on single Bitcoin implementation, btcsuite, fuzz testing; tracking proposal progress after voting and funding; why the wallet does not store the seed at all; power connectors, electricity, wiring and fire safety; reasonable spendings from project fund; ways to measure sync progress better than block height; using Politeia without email address; concurrency in Go, locks vs channels. #support is not often mentioned, but it must be noted that every day on this channel people get high quality support. (@bee: To my surprise, even those poor souls running Windows 10. My greatest respect to the support team!)
In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August. As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx) Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.
ASIC for Lyra2REv2 was spotted on the web. Vertcoin team is preparing a new PoW algorithm. This would be the 3rd fork after two previous forks to change the algorithm in 2014 and 2015. A report titled The Positive Externalities of Bitcoin Mining discusses the benefits of PoW mining that are often overlooked by the critics of its energy use. A Brief Study of Cryptonetwork Forks by Alex Evans of Placeholder studies the behavior of users, developers and miners after the fork, and makes the cases that it is hard for child chains to attract users and developers from their parent chains. New research on private atomic swaps: the paper "Anonymous Atomic Swaps Using Homomorphic Hashing" attempts to break the public link between two transactions. (bitcointalk, decred) On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange. Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.". Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred) The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights. A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

Alright, I keep seeing you fucks talk about how "Bitcoin is going to make Nvidia/AMD go to the moon". I'm going to walk all you fucks through bitcoin, crypto currencies, and how they effect the GPU market. What is Bitcoin? Bitcoin is a decentralized ledger. That's pretty much it. A set number of bitcoin is generated per block, and each block is solved when a resulting hash is found for the corresponding proof of work. The difficulty is adjusted periodically based on a formula, meaning that as hash rate rises and falls, the number of bitcoins produced per day is roughly the same. What does Bitcoin have to do with AMD and Nvidia? Fucking nothing. Bitcoin is mined on proprietary hardware called Application-specific Integrated Circuits (ASICs). Neither AMD or Nvidia produce these. Why does everyone keep talking about Bitcoin and AMD then? Because they're fucking retarded and you're listening to retards. Bitcoin runs on the SHA-256 Hashing Function which people have custom hardware for. The Crypto driving GPU sales is ETHEREUM, NOT BITCOIN What the fuck is Ethereum then? Don't worry about it. It's for smug assholes who are too edgy for Bitcoin. All you need to know is it runs on a different Hashing function than Bitcoin, so if you weren't a retard you'd probably realize that the proprietary hardware I talked about earlier won't work with it. Currently Ethereum is being mined the same way Bitcoin was when it first started; on GPUs. When are you going to tell me what to buy Shut the fuck up, learn something or kill your self. How many GPUs are being used to mine currently? Currently the Ethereum Hash Rate is 73,000 GH/s. For upcoming earnings, we should instead look at the period from April to June. April 1st shows a network hash rate of 16,500 GH/s, and June 31st shows 59,200 GH/s, meaning the network hash rate increased by 42,700 GH/s for this upcoming earnings report quarter. I've linked a decent benchmark for GPU hashrate . You should notice that all of these are quoted in MH/s, versus the Network reporting in GH/s; there are ALOT of fucking GPUs running on the network. A top of the line 1080 puts out about 20-25 MH/s, a good Radeon card does about 30. As a rough estimate, lets assume that the average card mining Ethereum currently produces about 25 MH/s. 42,700GH/s / 25MH/s means that there are 1.7 MILLION more GPUs currently mining ethereum than there were at the beginning of Q1. Based on my personal observations being involved in this, AMD is actually taking a majority market share of the sold cards just due to their superior performance compared to Nvidia's 1080s, and I'd estimate that About 50-60% of the cards currently mining Ethereum are AMD Radeons. What does this all mean? AMD are selling their highest margin video cards faster than they can produce them, and at ~250$ a pop with 50%-60% market capture AMD will have sold roughly 200-300 million dollars more in video cards than they did last quarter. AMD quarterly revenue last reported was just under 1 Billion. This is a 20-30% increase in revenue from last quarter, where Ethereum Hash Rate only increased by about 10,000GH/s. Even assuming a modest 30% margin for their video cards, AMD will still have almost 60 million in unexpected earnings this quarter due to crypto mining, which translates to about .06-.1 per share in earnings. tl;dr Ethereum will make AMD beat revenue by 20-30%. BUY AMD YOU CUCKS.
The $22,484.00 Butterfly Labs Mini Rig bitcoin miner is a huge, broken, unstable piece of shit.
(This was a rather controversial article posted on Buttcoin.org and became quite popular, even moving to the top of /bitcoin. It's since been mysteriously edited on the site [maybe by g-g-g-ghosts!] so it's being reposted here for posterity's sake. Some numbers may be off by now, but it was all accurate at the time of posting.) Butterfly Labs has a long and horrible history with their mining rigs. They started taking pre-orders over a year ago, with a ship time sometime in late July. After numerous delays in production, shipping problems and general incompetence, the only thing they’ve managed to get out the door are some of their tiniest miners, the Jalapenos. And those mainly ended up in the hands of reviewers and blogs in order to keep pumping the Butterfly Labs hype train and securing millions of dollars of pre-orders still in limbo.Lucky BFL forums user Luke-JR however scored a sweet Mini Rig from Butterfly Labs (it’s just a coincidence he’s a driver developer for them I’m sure). This rig was originally promised to produce 1500 GH/s hashing power at 1500 watts for $30,000, but has since seen it’s hashing power slashed to a third of what was promised and it’s power consumption increased 75%, now just offer 500 GH/s at 2400 watts. They’ve promised to make good on pre-order buy sending out 3 rigs to match the initial hashing rate, so now it’s only 1500 GH/s at 6900 watts, a reduction in GH/Watt by a factor of 5. So what does $22,484 buy you? Take a look!
Minirig is here! Today, my Minirig arrived. http://i.imgur.com/Yp0WPvE.jpg FedEx apparently dropped it somewhere along the way, and the weakest part of the case, the thin metal part around the back of the PSU, broke. http://i.imgur.com/lFcOHxP.jpg I’m not sure how sturdy the back side was supposed to be, but its two pieces aren’t quite together either. http://i.imgur.com/AVttcOt.jpg The power supplies (EVGA 1500W) also created havoc interfering with the neutral on the power line. This disrupted X10 communication significantly enough that the pool overflowed because the system controlling it was unable to turn off the pump. Workaround: This PSU supports 240V, so we rewired the outlet. 240V does not use neutral, so now all should be okay. Edit: 240V workaround is only partial. Still having problems But the good news is, it all seems to be working for the most part. Next up, installing it in the window so the heat goes outside
A twenty two thousand dollar box of electronics that is broken out of the box, that required the guy to do a sketchy electrical workaround to get partially working, that he is going to install in a window… and he’s happy about it? In case you didn’t notice it, the delivered unit is different than the picture on the website. They had to install 2 power supplies instead of 1 and had to modify the case to fit. Also, if you didn’t notice, the LCD/Phone thingy in the front has been replaced by … a piece of cardboard spray painted black. Wonderful. You could maybe chalk this up to a careless Fedex postman, but when you’re shipping something that costs as much as a mid-sized sedan, how bought putting a little more effort into packing? Dell and HP can ship bigger and heavier servers across the world without this kind of problem. The unit had to hit its huge power draw increase by putting dual EVGA consumer grade power supplies in the unit. We’re talking almost a 75 amp load (6*1500/120), disregarding power factor. He could very well overload the circuit panel and trip the main breaker for the house. Let’s take a look inside this guy. This is from an earlier version of the Minirig (note the single power supply) This is apparently from an earlier FPGA but it will give you a good glimpse at what kind of craftsmanship you can expect from a computer that is half the average household income in the United States. Consumer grade PSU and cheap USB hubs glued to the inside case. Electrical tape and random velcro glued to the insides A closer look at the USB hubs. Plugs are hot glued to stay secured. Electrical tape everywhere, splices and voided hardware are the theme. You can view the entire album here. Despite all that, this thing can still mine bitcoins and it should be profitable. Keep in ind that many people jumped in on the preorders a year ago when bitcoins were still hovering around $6.50 per. Meaning customers paid 1562 bitcoins for that particular piece of shit, which at today’s value is $156,200. Aston martin money. How long will it take them to make their money back (as apposed to just hanging on to them)? If the difficulty didn’t change, they would make 37 bitcoins a day and recoup the initial investment in 124 days. Difficulty is jumping pretty much 20% every 12 days or so, so in the next week before adjustment, they’ll make 259, the next 12 days 369, the next 12 days 312, then 256, then 213, etc. So by day 127, they’ll be halfway to breaking even, but by day 151 they’ll be making less than 5 bitcoins a day, and even if difficulty stopped rising at that point(which it won’t), it would take another 435 days for a total of 586 days to break even. If difficulty kept rising at the same pace, by day 200 they’d be making 2.4 bitcoins per day, and it would take 1024 days to break even with no difficulty increase. Assuming 25 cents per kw/h, and $100 a bitcoin, it would cost 0.43 of a bitcoin per day in electricity which means the unit would no longer be profitable on a power usage basis by day 307, at which point it will have produced 2620 bitcoins. Bear in mind this is only for the first few units, and that’s running 24/7 pumping out around 24,000 BTU, so yes, medical bills from heat stroke will be on top of that. But Alas, the chips don’t run nearly as well as they’re supposed to, frequently running too hot and giving multiple hardware failures. Coindesk noted in one of the first ever runs of the Minirig by hosting provide gigavps that it was running much too hot and erroring out.
At the time of posting, gigavps warned that the unit would be repeatedly shut down while ckolivas, who was assisting, modified the machine’s software to optimise performance. After some tweaking, the device was said to have been left to run continuously for two hours, and was shown to have an average hash rate of 478.1 GH/s. As you can see in the table below, ASIC number four (of a total of eight hashing chips) ran significantly hotter (86 degrees) and consequently gave the highest hardware (HW) error rate. http://i.imgur.com/q3iGrnb.jpg
So, what happens if you just decide you don’t want this, you don’t want to wait over a year to get a $22,000 broken piece of shit? Nothing, because BFL won’t let you cancel your preorder because they’re now “shipping”, i.e. they sent out one unit to their own company shill. http://i.imgur.com/0p3Up03.jpg Which is of course illegal regardless of what Butterfly Labs may say. So in summary: Don’t buy anything from Butterfly Labs … ever.
Where is the network difficulty headed, come November?
Reposted for accuracy. (Read: My math skills are the result of public education.) KNCMiner announced today that they're doing encapsulation on their new Scrypt ASIC chips, and then when they're completed, will be shipping to Stockholm for integration and testing, buildout and finally...shipping! I have read on forums that they have sold 3,000 Titans via pre-order, for batch 1, at 250MH/s nominal performance, each. I figured it was time to look at my "hashrate/difficulty prediction" again and see where it may actually be, by the time the snow's falling. All of the below is calculated with a Litecoin price of around $5. Let's assume for a moment that both Alpha Technology and Mining ASICs Technologies have also sold around 3,000 systems on pre-order (probably a safe bet) and all three expect to ship in September-October. 9,000 systems @ 250MH/s = 2,250,000MH/s. That's somewhere in the neighborhood of 2.25 TH/s being added to the network in roughly two months' time...that we can account for. The current network hashrate, as I post this? Not quite 1 TH/s...it's 896 GH/s. But at the current rate of network expansion, we're going to be 1 TH/s by the time these systems ship, easily. So...let's say we're looking at a 3.5 TH/s Litecoin network by November. What does that mean? When the Bitcoin network hit 3.5 TH/s back in May of 2011, the difficulty was around 244,000. Litecoin's difficulty is currently around 28,000. You can probably see where this is going, already. Fun with mining calculators time. Say you have one 250MH/s miner and deployed it TODAY (impossible, but for the sake of argument). You're looking at pulling in 9 LTC/day with it. If you pay $.10/kwh you're very lucky not to live in California, but we'll say that's the case. You pay around $4.50/day in power. So you walk away with $42.50 worth of Litecoin, at $5/each. If you somehow managed to freeze the network at that difficulty and the coin at that price, you'd pay off your $9,200 purchase of hardware in roughly seven months or so...or if you bought a Titan at $10,000 you're looking closer to eight. But since difficulty marches on, forget that entire concept. Now...say you get your system after all three companies have shipped and their customers have deployed them, and we've seen the network rocked to the tune of two-and-a-quarter terahashes per second. Oh, it's a rosy picture... Now, with the network difficulty having blown up to 244,000 the miner with a 250MH/s system is mining 1.03 Litecoin per day. And if my estimates are correct...this is NOVEMBER, we're talking about. At the current price of $5/LTC and $.10/kwh you are pulling down a healthy $0.80/day in profits, after power. If you again had the power to freeze the hashrate and price, you'd be able to pay off that hardware purchase in, oh...roughly 35 years. To have a REASONABLE shot at getting a return on your investment (around 5-6 months), Litecoin will need to be $70 by November and climbing steadily, in concert with network hashrate. Bear in mind, again that there is nowhere else for that hashrate to go but Litecoin. Nothing else will profit the Scrypt miner. So what will happen? There is built-in hardware cost here that has to be recouped and the only real way of doing that is by mining...and there's only one game in town for Scrypt mining: Litecoin. It's going to be a really, really wild fourth quarter for this year. Either the miners mine and hoard, decreasing supply and demand increases radically, or miners take heavy losses on hardware, can't afford to run them and the Litecoin network contracts until they CAN make money with them. In the interests of self-preservation, I have a feeling miners will start hoarding. Soon.
Need help choosing hardware/what to mine with just 200$ or less.
Hello guys, I am digging deep on the internet to try and find this question but any help is really appreciated. Noticing how my country is getting really awful in terms of currency exchange (Venezuela), getting USD is pretty valuable in here so I'm considering to mine for profit. I am really new on this, and I've just heard the bitcoin basics and the mining basics a couple of weeks ago. I only have available around 200$ to invest on an ASIC miner if it's really worth it, seeing that my 'calculator' is really awful to use as a miner (Gave it a try, and I could only get 80 H/s tops). The question is: What to mine? What can be truly be spent for a profit? I know miners can break even but here's the thing: Watts doesn't matter. Here where I live the electricity bill is around 0.0003 kWh, so no need to go green. My choices are either spend 3 AntMiner U3 (45$ each, 63 GH/s SHA-256), or 1 single ZeusMiner Cyclone (195$, 22MH/s, Scrypt), but I'm all ears if there are other more profitable choices. Any suggestion is appreciated, thank you.
Overview - Table of Contents Introduction to Earning in Bitcoin Work for Bitcoin Sell for Bitcoin Affiliate Programs Gambling Bitcoin Mining Hardware Mining Cloud Mining Introduction to Earning in Bitcoin Bitcoin is the most popular digital currency in the world today. Bitcoin cloud mining is the fastest way to immediately begin earning bitcoins. Bitcoin is built using very complicated cryptographic principles, and supported by countless individuals and companies from all around the world. By early 2016, total Bitcoin market capitalization had crossed USD 7 Billion, making it almost as valuable as the GDP of a small country like Bahamas. All the other digital currencies together do not constitute even 20% of Bitcoin’s market capitalization, underlining the its dominance and importance in the world of digital currencies. With such a huge amount of world’s capital available in the form of Bitcoins, the number and types of opportunities to earn in bitcoins are increasing by the day. In this article we will discuss such opportunities that help us earn bitcoins. We will start with the easiest, or the one that is applicable for the maximum number of people, and then move to the tougher ones. In the end we will cover earning bitcoins by mining. Bitcoin mining is not an easy way to earn bitcoins, but we do have a number of easier ones we will discuss first. So lets start with ‘earning bitcoins by offering your services’ Work for Bitcoin Perhaps the easiest way to earn bitcoins is to work online or in real life for bitcoins. Because of the huge size of the bitcoin eco-system, a number of such opportunities and jobs are available. With Billions of dollars invested in Bitcoin by tens of thousands of people, there is a real market in Bitcoin, where you can find jobs for freelancers, software developers, writers, and others who get paid in bitcoins for their services. Software development, writing, design, making websites or apps, audio transcription, are some of the most active types of jobs. You can easily discover the types of jobs by going over the more popular job boards for bitcoin related work. The following job boards or forums are some of the best places to look for such jobs or gigs. Freelancing XBTfreelancer Cryptogrind Bitlancerr Coinality Bitgigs Jobs4Bitcoins Rein Project Crypto Jobs List Market Places OpenBazaar Purse.io Bitify /bitmarket 21 Market Video Streaming Watchmybit Streamium.io Tasks Bitasker BitforTip WillPayCoin File/Image Sharing Supload.com SatoshiBox JoyStream Advertising CoinAd A-ads Coinzilla.io Also, check BitcoinGames for ideas on earning bitcoin and blockchain game assets. Sell for bitcoin You can also get Bitcoin by selling your old laptops, phones or other items for Bitcoins. Such types of transactions are happening more and more, and a lot of buyers are already buying anything from iPhones to even cars by paying with Bitcoins. For Americans, Craigslist.com is your best bet when you want to find such buyers. You can mention in your ad that you are willing to take payment in Bitcoin. This way if anyone wants to buy the item for you for Bitcoin, they can contact you and make an offer. The same principle applies to other online marketplaces such as gumtree for UK, kijiji for canda etc. Affiliate Programs Affiliate programs allow a promoter of a business or product to earn money or bitcoins by refering new clients to such businesses or products. For example, amazon.com has a popular affiliate program, where you can earn commission ranging from 2% to 20% for refering clients to products listed on amazon.com. Amazon normally pays in dollars, but there are a number of other sites and businesses which pay you in bitcoin for acting as their affiliate. Some of the more popular affiliate programs that pay out in Bitcoin are by the sites: cex.io, coinbase.com, okcoin.com and namecheap.com, among others. You can find a larger list of such affiliate programs on the bitcoin wiki page for Affiliates. Gambling We do not recommend gambling for every player or every user; we find that gambling is only suitable for people who know how to win at it. However, if you are one of such lucky users who have some tricks up their sleeves, and can manage to win at games such as poker, then you will find that earning bitcoins is not that hard. One of the many applications of bitcoin since the very beginning have been in betting games or gambling. Because of the relative anonymity of bitcoin, and the lower fees, it is very suitable for gambling related applications. Indeed, one such game, satoshiDICE, has been running since 2012, and has paid out a huge number of bitcoins in innumerable transactions to its winners. There are many such games, which you can find be googling. If you want to gamble totally anonymously, you can play gambling or betting games that are available only on darknet or .onion sites. Such sites allow you to browse them anonymous by operating on the tor network, which is a secure network that allows users to browse .onion websites without exposing their own IP address. Bitcoin Mining For each block that is added to the Bitcoin Blockchain, a number of bitcoins are rewarded to the creater of that block. This reward is currently, as of June 2016, 25 bitcoins per block, and it halves every four years. The next halving will be in July 2016. Creating or finding the new blocks, and therefore winning the reward of 25 bitcoins for each block you create, is called bitcoin mining. To do bitcoin mining successfully, you need very powerful computers, which compete with other computers to find the next block. The speed or power of computer that do bitcoin mining is calculated in hashes calculated per second. There are two ways to do bitcoin mining: one is to own hardware or computers that do the mining, and second is to hire the hardware from a third party, usually online, and do the mining on the cloud. Let us discuss the advantages and disadvantages of both in next two sections. Hardware Mining When you own the hardware that does the calculations and mining of bitcoins, its called hardware mining. Hardware mining is the more popular or prevalent of the two types of mining we mentioned. One of the biggest factors which comes into play when doing bitcoin mining using your own hardware is the price of electricity. If you pay top price for electricity, then bitcoin mining may not be your cup of tea. Another related factor is infrastructure needed to cool the hardware; since every cpu generates some amount of heat, you may need to cool the hardware in case they become too heated. No wonder that some of the most successful miners work from China, specially Tibet, where they can get cheap electricity, and their cooling costs are low due to high altitude which reduces the ambient temperature for them. For a more in-depth information on how to setup your hardware mining equipment, have a look at the Antminer setup page. Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are: AntMiner S7 AntMiner S7 Bitcoin Miner 4.73 Th/s 0.25 W/Gh 8.8 pounds Yes $479.95 AntMiner S7 Bitcoin Miner 0.1645 AntMiner S9 AntMiner S9 Bitcoin Miner 13.5 Th/s 0.098 W/Gh 8.1 pounds Yes $1,987.95 AntMiner S9 Bitcoin Miner 0.3603 Avalon6 Avalon6 Bitcoin Miner 3.5 Th/s 0.29 W/Gh 9.5 pounds No $499.95 Avalon6 Bitcoin Miner 0.1232 Cloud Mining There are a number of service providers that allow you to rent computational hardware from them, which can then be used to do bitcon mining. Some of these services are designed with bitcoin mining in mind, whereas others such as Amazon AWS are general purpose services that can also be used to do bitcoin mining. Some of the cloud mining services which can be used to do bitcoin mining on the cloud are: Hashflare Review: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s. Genesis Mining Review: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider. Genesis Mining offers three Bitcoin cloud mining plans that are reasonably priced. Zcash mining contracts are also available. Hashing 24 Review: Hashing24 has been involved with Bitcoin mining since 2012. They have facilities in Iceland and Georgia. They use modern ASIC chips from BitFury deliver the maximum performance and efficiency possible. Minex Review: Minex is an innovative aggregator of blockchain projects presented in an economic simulation game format. Users purchase Cloudpacks which can then be used to build an index from pre-picked sets of cloud mining farms, lotteries, casinos, real-world markets and much more. Minergate Review: Offers both pool and merged mining and cloud mining services for Bitcoin. Hashnest Review: Hashnest is operated by Bitmain, the producer of the Antminer line of Bitcoin miners. HashNest currently has over 600 Antminer S7s for rent. You can view the most up-to-date pricing and availability on Hashnest's website. At the time of writing one Antminer S7's hash rate can be rented for $1,200. Bitcoin Cloud Mining Review: Currently all Bitcoin Cloud Mining contracts are sold out. NiceHash Review: NiceHash is unique in that it uses an orderbook to match mining contract buyers and sellers. Check its website for up-to-date prices. Eobot Review: Start cloud mining Bitcoin with as little as $10. Eobot claims customers can break even in 14 months. MineOnCloud Review: MineOnCloud currently has about 35 TH/s of mining equipment for rent in the cloud. Some miners available for rent include AntMiner S4s and S5s.

GPUs will make a comeback to mining, and in doing so, will destroy the security of the Bitcoin network
The reason why Bitcoin is relatively secure right now is because the cost to mine is extraordinarily expensive. Why is it so expensive? Not because of the cost of the silicon, or even really the cost to manufacture, but because the only use of an ASIC is for mining SHA-256 cryptocurrencies such as Bitcoin. When people pay up to $15,000 for an ASIC miner, they're paying for all the time and effort that went into it. But consider this: What if mining machines become multi-purpose? In particular, what if GPUs return to the fore as competitive mining machines? Now I know what you're thinking; you're thinking 'You fool, GPUs will never come close to the efficiency of an ASIC'. But the thing is, they don't need to be. They only need to be cheap, since the purchase cost of an ASIC greatly outweighs its electricity cost. A 'CoinTerra AIRE' ASIC slated for release in March this year will cost $2499 and do 4500 GH/s. Now taking into account a number of factors like electricity cost and rate of value depreciation, I'd estimate that for a $200 GPU to be competative, it needs to do about 225GH/s - an improvement of 375x on current hardware. Impossible you say? Well, the hash rate of nVidia GPUs has improved by ~70-80x in just a few years, without any intentional focus towards Bitcoin: 5.66 MH/s 8600GT to ~414 MH/s GTX 960. The nVidia GTX 780ti is a top of the line card currently priced at $440 and it does 0.5 GH/s, yet an Ati 280X which costs just half the price does at least 0.7 GH/s. Ati cards have always displayed better performance in mining, but why? I'm no expert on the technical details, so I'll only say what can be deduced and is relevant: GPU designs can be altered to increase efficiency/performance when it comes to Bitcoin mining - this is a proven fact from the Ati/nVidia difference! So far, these chipset makers have no doubt been focused on improving gaming performance. But what if they realize that there are many people who will buy more of their GPUs if they have the added benefit of good mining performance, as in 2011? Surely it wouldn't be too difficult or expensive to rearrange things a bit or slap a few things on - If a bunch of amateurs can create ASICs, how difficult could it be for a multi-billion dollar company to improve the hash rate of their GPUs at minimal extra end cost to the consumer? Or what if gaming just naturally tends more towards GPUs having better hash rates? When this happens, Bitcoin will have a security crisis on its hands. There are millions of people with mid or high level graphics cards. In Q1 2014, AMD and NVidia sold a combined 14 million add-in boards. But let's be conservative - let's use the publically available Steam data, which says that yesterday there were a peak 8.3 million concurrent users online. Steam's hardware survey says about 65% of these are not mid or high level cards, so 0.35 x 8.3 mil = 2,905,000 people with decent AMD or nVidia cards who are conscious users (i.e. not office workers) at a certain time of day. For those 2.905 million gamers to launch a concerted and sucessful 51% attack on the network, their GPUs would only need to do on average 57.14 GH/s. If $200 GPUs were to be doing 225 GH/s, the entire number of ASICs throughout the world would be no match! If you want a 'tl;dr' then go listen to Fenton or Shrem egg you on to buy or something - stay in your little dreamland while the price falls like a rock

Conclusion: If you decide to buy your own hardware it will will stay yours forever. Nevertheless, keep in mind that you need a storage place for your mining rig and have to deal with the noise, so it should not be turned on 24/7 in your apartment. Scrypt: 7.5$ for 1 MH/s -> 3750$ for 500 MH/s Fees: 0.01$ per every 1 MH/s (currently approx. 62% of daily earnings) ->(cf. real miner only 15%) Profit: 9.54$-7.5$(Hardware)-5$(Maintenance)=-2.96$/year per 1 MH/s -> -1480$/year per 500 MH/s) Scrypt(real L3+ Miner): 5$ for 1 MH/s -> 2500$ for 500 MH/s Fees: 0.0038$ per every 1 MH/s (currently approx. 15% of daily earnings) ->L3+ mining rig (800w with 0.1$ Cost pet KW/h) Profit: 9.54$-5$(Hardware)-1.387$(Maintenance)=3.153$/year per 1 MH/s -> 1576$/year per 500 MH/s But keep in mind that you can sell your hardware at any time as it stays yours forever (not 1-Year Contract) Profit w/o hardware: 9.54$-1.387$(Maintenance)=8.153$/year per 1 MH/s -> 4076.5$/year per 500 MH/s Conclusion: At this point I strongly advise not to buy any Scrypt contracts on Hashflare since you will end up losing money by doing so unless LTC suddenly skyrockets. As other Hashflare contracts (Zero-fee contracts) are not profitable in my opinion, I will only briefly summarize the results: ETHASH: 2.2$ for 100 KH/s -> 220$ for 10 MH/s -> yields approx. 153$/year (0.51ETH), thus you will lose 67$ unless ETH goes magically up X11: 3.2$ for 1 MH/s -> 320$ for 100 MH/s -> yields approx. 60$/year (0.2 DASH), thus you will lose 260$ unless DASH goes magically up EQUIHASH: 2$ for 1 H/s -> 200$ for 100 H/s -> yields approx. 127$/year (0.54 ZEC), thus you will lose 73$ unless ZEC goes magically up To sum it up, of course you can try your luck and hope that one of the altcoins will skyrocket to the moon and then you will make some money by joining these contracts. Nevertheless, you could also simply buy the following altcoin and make some money by simply holding the altcoin currency on an exchange. So as far as I am concerned, the only reasonable contract in Hashflare at the moment is the SHA-256 Contract. https://www.eobot.com/new.aspx?referid=261758 (founded 2013): Eobot offers several contracts like Cloud Folding, SETI, Scrypt etc. Though they are not very profitable and thus I dont want to discuss them in detail. The only reasonable contract would be the SHA-256 5-Year Rental: 6.8$ for 10 GH/s (cf. Hashflare only 1.5$) but also keep in mind that it is a 5 Year Contract and not one year contract(cf. 1.5$*5=7.5$ for 5-Year Hashflare SHA-256). SHA-256 5-Year Rental: 6.8$ for 10 GH/s Fees: 0.0021$ per every 10 GH/s (cf. Hashflare 0.0035$) Profit: 3.79$-(6.8$/5=1.36$)-0.77$(Maintenance)=1.66$/year per 10 GH/s -> 2158$/year per 13 TH/s (cf.

What is interesting about this site is the fact that you can buy other people´s cloud mining power vice versa (can sell it back at any time) on the Market. It is very beginner-friendly since they have the possibility to start with as little as 8000 Satoshi and buy 1 GH/s. Yet keep in mind that the withdrawal fee is 20.000 Satoshi, so you should invest at least 40.000 Satoshi in order to make some money after the withdrawal fees are deducted.

https://forums.butterflylabs.com/announcements/692-bfl-asic-status-3.html 22 May 2013 Progress has not stopped here at the labs while we attended the 2013 Bitcoin Conference. We demonstrated a 5 GH/s, a 25 GH/s and a 50 GH/s miner at the conference that people could see, touch, stroke and pet, all while they were mining on an Android tablet. It was a good conference and we were glad that we could demonstrate working units and meet many of our customers and fellow bitcoiners. It was a pleasure meeting many of you. We have resolved the issues with the long boards and are making some tweaks to the 5 GH/s boards that may reduce power consumption but will almost certainly reduce heat output. With that in mind, we should be getting about 200 5 GH/s boards on Friday, and we'll be shipping those out on Friday and Saturday. As a term/jargon/technical note, here is the informal and/or official designations here at BFL: Short Board = ~92mm x 92mm board that contains up to 8 chips and powers the 5 GH/s miner, typically with just 1 or 2 chips. Long Board = The board that powers the Little Single, Single and Minirig and can contain up to 16 chips in two banks of 8. Jalapeno is now called the 5 GH/s miner and is synonymous. The Minirig is now a 500 GH/s unit. Our chips consume about 3 - 3.5w per GH/s at the chip level, so there is some room for tweaking, which we will be focusing on as soon as we get the final rev out for the Long Boards. Speaking of Long Boards, we have what we are considering the last rev for shipment coming next Monday or Tuesday the 27th or 28th of May (they may even be done with manufacturing this Saturday the 25th) and we will continue to refine the firmware for that board until the final rev arrives in KC. Assuming no problems with it, we will be being shipment shortly thereafter. The long boards will be powered by one or two PCIe style 6 pin Minifit Jr connectors. Please be aware that these connectors, while using the same form factor as PCIe connectors are not PCIe connectors, though they are electrically compatible with them (Meaning you can likely use an ATX PSU at your own discretion if you chose not to use our supplied power bricks). The Little Single and Single will have a 120mm fan at each end of the case in a push/pull configuration. Each bank of 8 chips will have a heatsink, heat baffle and 92mm fan on top of it. Cooling will not be an issue with these units and they will be fairly quiet to run if you are in a cool environment. The fan will scale up and down in speed as required due to heat. The units will be stackable and have a side to side or front to back airflow, depending on how you orient them. We are expecting several thousand chips next week from our new packaging facility and expect to start shipping all product lines next week. Beyond that, we will be receiving thousands of chips per week at an ever increasing pace between now and until all of the remaining 68 wafers are used up. We have additional wafers on order and they should be ready about the time we've used up all 68 wafers should we need them. Soon after, we hope to have product on the shelf for immediate shipment, depending on how many orders come in between now and when we catch up the backlog.
Vertcoin's "Total Network Hash" rate is at about 6.5 GH/s at the time of this writing. We double this 6.5 GH/s to indicate the comparative amount of mining hash that Scrypt v01, or non Adaptive N coins, generate per unit of Scrypt hardware hashing potential that is now mining Vertcoin. So Vertcoin now attracts the amount of mining hardware that would produce about 13 GH/s Total Network Hashrate for some Scrypt v01 coin. Litecoin is of course nearing 200 GH/s, Dogecoin is less than half of Litecoin's Total Network Hashrate at 85 GH/s and Vertcoin is at about 13 GH/s. Feathercoin is in fourth place with about 6.5 GH/s.
Litecoin == 200 GH/s (varies significantly over the medium term.)
Dogecoin == 85 GH/s (varies wildly over the short term)
Vertcoin == 6.5GH/s (13 GH/s) (varies less than other coins)
Feathercoin == 6.4 GH/s
For a relatively new introduction to the coin markets, Vertcoin performance is remarkable. We might have seen Vertcoin falter and fall into weakness, but we are not seeing that. We bottomed around 0.00135 bitcoin value, and now we are seeing a strong rally, a reversal, or series of rallies that retrace naturally to the short term 50% fib areas, and then another leg up ... The question is of course, how much of the increase in value of these recent rallies, (from the recent bottom), can Vertcoin maintain going forward? The newest Ace up Vertcoin's sleeve, Multivert mining pool, http://www.verters.com/multivert, where miners point Scrypt v01, (non adaptive N Factor), mining power at this new pool, the pool then mines the most profitable Scrypt v01 coins, sells them on the market for bitcoin, then purchases Vertcoin and pays miners in Vertcoin, this is probably one of the favorable and attractive new mining strategies, (to speculators as well as miners), accounting for some of the recent interest in Vertcoin in the markets, thus, the price increases. The absolute beauty of this new mining strategy is that to combat this strategy, to mine the more profitable Vertcoin with a Multipool operation, to mine VTC directly, and then DUMP the Vert on the market for bitcoin, and then pay miners in bitcoin, can only be accomplished by having miners point their hashing power at that pool, using vertMINER software, thus, the distribution of the Adaptive N Factor mining software would be of magnitudes greater than it is now to accomplish that. Vert coin miners understand that mining Vert, selling it for bitcoin, and then paying miners in bitcoin is not a step in the evolution of mining strategies. Perhaps the VTC for BTC exchange by individual miners, or farms, is tenable, but not a general MultiPool strategy. Vertcoin literally has proven that it is not tenable for a Multipool mining strategy where Vertcoin proceeds would be sold for bitcoin, thus, Vertcoin has a very definable victory here in the mining strategy markets. Along with Vertcoin's ASIC resistance, and strategies up the sleeve for further enhancement of ASIC resistance, Vertcoin puts itself in the spotlight and truly sets an example for CryptoCurrency moving forward. Vertcoin Multivert mining pool literally TURNS the TABLES on the mining strategy that has pounded so many alts with pool dumps mining the most profitable alt coins, selling market orders for bitcoin, and paying their alt coin mining miners ... in bitcoin. Moolah and others involved in getting a USD/VTC pair, or exchange for fiat launched is another favorable factor for Vertcoin.
Considering purchasing my first mining rig for pooled cryptocurrency mining.. any help is appreciated.
I've been considering purchasing a mining rig for a few months now and am ready to do so, but have some questions I've been unable to find straight answers for in my research. My initial investment is going to be $200-$300 that I am for the most part willing to lose, as this is just a hobby for the time being. I will probably start with an ASIC miner for SHA-256 based coins, as it seems to be the cheaper and easier choice for a beginner. I will not be looking to mine bitcoins as I understand the difficulty is ridiculously high, but rather would like to join an altcoin mining pool. So here are my questions: 1) Would it be better to start with a rasberry pi/USB block erupter set up which mines about 3 GH/s or a pre-built Block Erupter Cube that can mine about 30 GH/s? I can purchase the cube for about $100 more than the rasberry pi set up. What would be the difference in electricity costs on these units? 2) I understand that there are both SHA-256 based coins and Scrypt based coins. If I were to join a mining pool like hashco.ws where the pool switches cryptocurrencies often, will my ASIC miner be able to contribute to mining Scrypt based coins as well? How does that all work? 3) What returns can I expect to see mining at 30 GH/s on a site like hashco.ws or any other similar site? Obviously this will be a very rough estimate but really I'd just like to know if I'll be able to break even on electricity costs. Like I said, this will be a hobby so money isn't a number one priority, but not losing more money on top of my initial investment would be nice. I appreciate any help I can get! Thanks!
I'm looking to buy an Asic, and I'm trying to figure out which one to buy and where to buy it. I'm looking to spend up to $10,000 but I really just want the best bang for my buck. It looks like KNCminer is a pretty solid company, and their second batch of Neptune miners are going to be sold for $3,333 / GH, but I can get an antminer from bitmain for $2,200 / GH, that will ship within 48 hours. Wouldn't buying a few of these be a better investment than waiting on the KNC? Especially since the difficulty will have increased quite a bit by the time the KNC ships. Anyways, I'm pretty new to this, but if anyone has any of the following information I would really appreciate it.

Other things I should consider when investing in a bitcoin miner
I have been helping a friend develop business strategies at a Bitcoin start-up over the last few months. In the course of this work, the topic of Bitcoin mining appears often to be fraught with misinformation and uncertainty, especially for individual miners who unfortunately may find it difficult to return an adequate profit in many cases. This informal guide covers some important issues prospective miners should consider to avoid headaches and financial loss. The information is derived from experience deploying a 400 TH/s system scheduled to come online in around December. Opinions are my own; I’m happy to entertain constructive feedback. This year, the Bitcoin network will award miners nearly USD 500 million, at the current price of USD 375 per bitcoin, to participate in a process known as mining. Unsurprisingly, this has attracted significant interest not only from Bitcoin advocates, but from speculators and investors as well. Regardless of one’s motivations, the business of Bitcoin mining must ultimately be profitable, or at least operationally viable, if there is to be any chance of success. HOME MINING Acquiring and personally managing ASIC miners is probably the most fulfilling way to mine bitcoins. It provides the greatest level of transparency, but requires a certain level of technical proficiency to set up and run. Advantages: 1) No hosting fees payable 2) Full control of operating parameters 3) Direct payment from mining pool Disadvantages: 1) Purchasing the latest mining hardware is inherently risky because the ongoing development of energy-efficient ASIC chips requires expertise, time and millions of dollars. R&D is usually funded by customer prepayments with no guarantee of timeliness or success. It is not uncommon for miners to incur financial loss and opportunity costs when a supplier fails to deliver 2) The retail price of hardware is typically marked up anywhere from 25% to 500%, or more, depending on market conditions. This creates a barrier to profitability, making it harder for miners to recoup hardware costs if they are unable to negotiate for volume discounts 3) Shipping fees and import tariffs can cost hundreds of dollars per unit, especially if importing equipment from overseas. This adds to the cost of hardware and must be taken into account when calculating the return on investment 4) Shipping time varies greatly. Each day spent in transit incurs an opportunity cost 5) Miners need to set aside space, usually in the home, to locate mining equipment 6) Many mining units may generate excessive noise, and heat that requires around the clock ventilation to maintain an optimal operating temperature range 7) The average mining unit draws up to three amps of current. A system containing twenty units could easily exceed the power limit in a typical home 8) Electricity is by far the largest expense in any mining operation, making up around 90 percent of operating costs. If the price of residential power is materially higher than the rate paid by commercial operators, it makes home mining uncompetitive CLOUD MINING Buying into a cloud mining service is often marketed as a convenient and hassle-free way to get in on Bitcoin mining. As the mining assets are managed by an intermediary, getting a breakdown of operating costs prior to purchase often proves difficult. This makes it challenging for potential customers to make a fully informed buying decision. The unspoken truth is that some cloud miners incorporate obsolete equipment—cheap miners from previous generations or liquidated, unprofitable hardware—into their cloud to sell to unsuspecting customers. Older mining units can consume 80% more power than the current generation miners, leaving very little profit for the customer. In addition to the acquisition price, those in the market for cloud mining should consider the power consumption of the cloud on offer, including changes over time as new mining units are added to increase total capacity. Advantages: 1) Start earning immediately. No waiting weeks or months for equipment delivery, installation and set up 2) Convenient and fully managed mining service means customer needs not be technically inclined or involved in day-to-day operations 3) Professional hosting service ensures optimal performance and low operating costs. Commercial hosts may be able to purchase electricity for a materially lower cost than residential customers 4) Acquisition price is often reasonable. Sometimes, possibly, too good to be true 5) Some platforms allow miners to sell their assets to other traders Disadvantages: 1) Not all hashing power is comparable. For the same acquisition cost, more energy-efficient miners are better because they use less power and return higher profits. When buying hashing power from a cloud, the buyer should ensure he is not getting obsolete hardware. Often this is not possible to verify without a basic understanding of the costs involved, however subpar earnings is a good indication that further investigation is required 2) Hosting and cloud management fees are typically payable. Sometimes there is little transparency in pricing, resulting in unexpected cost to the customer 3) Miner has little input into how the cloud is managed COSTS BREAKDOWN The amount of money earned from Bitcoin mining over a short period of time, say one week, is fairly easy to calculate. Given mining is a zero-sum game where new entrants dilute existing participants and the mining reward is roughly shared on the basis of each miner’s contribution to the overall hash rate, we can derive profit by estimating the income and costs. Mining Income: Weekly mining bitcoins created = 25,200 = 25 bitcoins x 6 times per hour x 24 hours x 7 days Assuming hash rate is at 300,000 TH/s, bitcoins earned weekly per one terahash of processing power = 0.084 bitcoins = (1 terahash/ 300,000 terahash) x 25,200 bitcoins Table 1: Weekly earnings per one terahash of computing power
As new miners enter the market, an increase in hash rate dilutes the mining reward. This is the source of much uncertainty in mining because it is difficult to accurately forecast the rate of increase. Dilution reduces a miner’s income while the amount of work is the same. Mining Costs: Electricity typically comprises around 90 percent of total operating costs. The two determinants of electricity cost are price and the amount of electricity consumed. If we take a hypothetical 700 GH/s system that is rated at 490 watts, we can normalise it: 0.7 kW per one terahash = (1 terahash / 0.7 terahash) x 0.49 kW Electricity used per week is: 117.6 kWh = 0.7 kW x 24 hours x 7 days If we know the cost of electricity, the dollar value of electricity consumed in one week can be estimated. For reference, power prices in Australia are between USD 14 cents (commercial rate) and 19 cents (residential rate). China averages around 8 cents, while other places can be cheaper. For example, in Georgia, USA the cost of commercial electricity is around 6.5 cents per kWh. Table 2: Weekly electricity cost of running a one terahash system
Other costs to consider include mining pool fee (typically 1 percent of earnings), hosting fee (depends on host) and other expenses such as air conditioning if hosting at home, maintenance, etc. Profit: Using the assumptions that hash rate is at 300,000 TH/s and bitcoin price is USD 375, we can work out the profit. Moreover, knowing the basic cost of Bitcoin mining can help prospective miners avoid offers that are too good to be true. To simplify, we ignore other running costs: Profit = (bitcoin price x bitcoins earned) - electricity expense Table 3: Estimated profit from running a one terahash system for one week
These figures serve as a good benchmark for comparing your personal performance. Where the electricity price is known, the difference between the calculated and actual profits can be attributed to two things: 1) Energy efficiency of mining units can cause significant deviation, especially when the cost of electricity is high. This is usually the case if obsolete equipment is being used 2) Hosting fee, mining pool fee and other costs also contribute to the difference Return on Investment: The rate of return is a measure of how much miners make for a given investment size. Implied annualised return = (52 weeks x profit per week) / (hardware cost + shipping fees + tariffs + installation and setup costs) The current price of ASIC miners runs at around USD 500 per terahash, excluding international delivery and insurance that can cost between five to 20 dollars per kg ($50 to $200 per unit). As a general rule, higher operating profit and lower capital costs are preferred. Investors endeavour to break even quickly on the initial hardware investment and make a profit on top of that. The problem with this model is that it implies the hash rate remains unchanged for the entire year. In reality, the hash rate is likely to increase depending on a variety of factors. Therefore, the annual profit forecast is sensitive to changes in the hash rate as well as bitcoin price. This is a complex and interesting topic that deserves its own post. Please, keep in mind that actual mining results will very likely be less than what is indicated by this simple calculation. Under some scenarios, even informed miners can experience financial loss. OPERATING RISKS 1) Liquidity risk: Bitcoin trading is rather shallow. As such, miners may experience high trading frictions when selling bitcoins to obtain cash. A bid-ask spread of up to 10% is not uncommon in some cases. Furthermore, most mining businesses rely on the liquidation of mined bitcoins to cover operating expenses such as electricity and hosting. The combination of these two factors may result in unexpected trading costs to the miner if there is insufficient demand from bitcoin buyers. 2) Price risk: Bitcoin is highly speculative and this is reflected in its price volatility. There is no guarantee that it won’t be worthless by next year. Therefore, the miner should keep in mind that the market price is just as important as the amount of bitcoins he holds. Bitcoin price is influenced by multiple factors outside of the scope of this discussion. 3) Competition risk: Bitcoin mining is a zero-sum game. While the size of the reward is fixed, new entrants are permitted to enter at anytime reducing all miners’ share of the reward. When bitcoin price is high, more new competitors are attracted to mining, further eroding all participants’ income. 4) As a function of the Bitcoin protocol, the mining reward will be halved between May and June of 2016. When this happens, all miners will experience an immediate decline of 50 percent in income with many operators becoming unviable. This effectively gives new entrants less than 1.5 years to break even and turn a profit. The short window of opportunity is troublesome because it makes mining significantly less profitable as the deadline draws near.
So me and a friend want to start getting supplies for mining. A good question to ask for reddit!
So me and my friend want to start mining. Now, I have been asking questions, so no need to say I won't get profit at all from bitcoin. I know all this. But we are going to go ahead and do it. So I had a question or 2. I have heard of people selling these Avalon Asic chips that can preform 9 Gh or so. I was wondering, how hard is it to build your own miner? I would like to buy some chips and make my own personalized miner. That would be really nice. My dad works with airplanes so he has a lot of products he can use to build. We have tons of excessive boards and such. We could even ask the company to make a custom board. But I would need exactly how everything works. So if anyone has had experience building one, please comment! Also if anyone is selling their own custom built one for a good price, I would like to talk. Now I am not that rich, I live off of the keys I sell off of ebay. So be nice about price. It might take me a bit to get, but it will be done. Still waiting for about 200 dollars to come back in for a pc case. Now, one more thing we were wondering. Bitcoin vs Litecoin. Which one would be a TON better? My friend used to work at a PC store. So we were thinking we could Litecoin as well. They have a bunch of spares and they could get me some good radeon cards for cheap. I was wondering which one would be better price wise. Thanks!
