Bitcoinppi – Bitcoin purchasing power index

Can't get a small script to work anymore (Been starting to learn JSON) - Python3.

Hello. I wrote a script in Trinket.io last week.
I saved it to notepad++. When I pasted it back in today I get a whole host of errors. I am 99.9% sure it worked last week and nothing has changed.
Any ideas?
CODE #!/bin/python3
import json import time import urllib.request while True: url = 'https://api.coindesk.com/v1/bpi/currentprice.json' response = urllib.request.urlopen(url) result = json.loads(response.read()) bpi_json = result['bpi'] curr_json = bpi_json['GBP'] curr_price_json = curr_json["rate_float"] print ("The current price of bitcoin = "+str(int(curr_price_json))) if int(curr_price_json) < 8000: print ("buy some bitcoins you fucking idiot!!!") time.sleep(60) 
Output:
Traceback (most recent call last): File "/tmp/sessions/62ca088620b216f1/main.py", line 10, in response = urllib.request.urlopen(url) File "/uslib/python3.5/urllib/request.py", line 163, in urlopen return opener.open(url, data, timeout) File "/uslib/python3.5/urllib/request.py", line 472, in open response = meth(req, response) File "/uslib/python3.5/urllib/request.py", line 582, in http_response 'http', request, response, code, msg, hdrs) File "/uslib/python3.5/urllib/request.py", line 510, in error return self._call_chain(*args) File "/uslib/python3.5/urllib/request.py", line 444, in _call_chain result = func(*args) File "/uslib/python3.5/urllib/request.py", line 590, in http_error_default raise HTTPError(req.full_url, code, msg, hdrs, fp) urllib.error.HTTPError: HTTP Error 403: Forbidden 
Any ideas? I tried running it in Geany inside my LubuntuVM but same result.

An analysis of BTC fundamentals

Disclaimer: This post is not an endorsement to either buy or sell Bitcoins. I am simply attempting to outline the reasons why there is inherent value in Bitcoins, as well as the risks that come with investing in a crypto-currency. In full disclosure, I personally own and use them, but only a very small portion of my overall portfolio which I would be ok if BTC went to 0 tomorrow.
Purpose: I’ve been seeing a lot of doom and gloom (as well as irrational exuberance) in a lot of posts lately, and a lot of people saying this or that with no evidence or fundamentals to back up their claims. So I wanted to put my thoughts and experiences [more about me below] out there in the hopes that people actually serious about utilizing Bitcoins (BTC from here on) might find this information helpful, as well as to connect with and solicit thoughts from anybody else that’s done research on the future of BTC. Also mods: I searched through old posts and the FAQ but couldn’t really find anything like this, so let me know if there is a more appropriate place to post this. I can also add hyperlinked sources to this to make it a reference document if there is interest.
Summary/tl;dr: The fundamentals underlying the intrinsic value of Bitcoins haven’t changed. In fact, they continue to improve day-by-day, as merchant and user adoption increases. As long as this trend continues, and certain risk factors - see below - are minimized, BTC will eventually become widely accepted as a currency.
That being said, you should never “invest” more money than you are willing to completely lose, or money that you would otherwise need for living expenses. Otherwise, you are gambling. (I put “invest” in quotes because I believe BTC are currently far too speculative to be considered an “investment.” This may change in the future, but the technology is still so new, and there are so many unknowns, that it should not be considered anything more than a speculative investment at this point.)
This has happened before and it will happen again: This week hasn’t been good for those holding Bitcoins. In fact, if you invested in BTC anytime in the past year, I’d say it’s been a pretty shitty year, period. But the thing is, we’ve seen this type of thing in financial markets before, almost exactly to a t, and how they tend to play out. There have been various bubbles of all shapes and sizes throughout history, and the run-up in prices earlier this year, was no exception. However, unlike the critics, I believe BTCs are different, as there is significant intrinsic value in the BTC network and BTC as a value store - which I outline below.
I also think it’s useless to speculate about the direction of BTC in the short to medium-term (I would argue the price adjustment has been a good thing for the long-term), so to me the only meaningful way to analyze what’s going on is to examine the fundamentals (apologies if a lot of this is basic, but I wanted to cover all the key points as I saw them):

Value:

So I’ve briefly outlined above some pretty clear reasons why there is inherent value in BTC, and the reasons why I personally am optimistic about the long-term future and will continue to use them. That being said, I’ve also identified several primary risk factors that worry me as a long-term investor, ones that all holders of BTC should be aware of. Please, if you know or can think of any others, reply or PM me so I can add them to this list:

Risks:

I could go on, but those are the major value and risk factors I see. If you have anything to add, please feel free.
So, in the context of everything I said above, I’d like to talk about what happened this week in particular:
I believe this week’s price movement (as of me writing this, has been a 25% drop) is a result of several factors:
  1. News that US Dollar is very strong
  2. Capitulation: I don’t have the ability to do Technical Analysis on BTC right now, but just eyeing the 1-year chart, it looks like $400 was a key support point for the price of BTC. Once it broke through that, psychological barriers were broken and selling cascaded.
  3. Russia and China potentially banning BTC
And that’s it. That’s all I can find about Bitcoins in the news. The value fundamentals I listed have not changed one bit, and if anything, the rate of user adoption has increased as more people are learning what it is.
Which is why I’m excited about the future of BTC. It’s a product that I use and like, and see tremendous value for. This week’s sell-off just means I can buy more.
About me:
In a past life, I was an equity research analyst responsible for due diligence, fundamental/technical analysis, and making recommendations to the PM on which stocks a certain mutual fund should buy or sell. This meant reading through a lot of annual reports, financial statements, 10-K, 10-Q, shareholder calls, etc… My primary influences were Warren Buffett, Philip Fisher, and Ben Graham. If you recognize these names, you’ll probably guess that I was a value investor1 , and you’d be right. The fundamental premise behind value investing, for those that don’t know, is that you can find companies that are trading at a discount to their “true” intrinsic value, and thus can make money by buying the stock at a low price and selling when the market has realized the fair value of the company and the price has subsequently gone up. This is essentially how Warren Buffett built Berkshire Hathaway and became the world’s richest man (for a short period); his strategy has since greatly evolved, but this was the core philosophy he used for a long time.
1 Utilizing this strategy, our fund bought a significant stake in AAPL when the price per share was less than the amount of cash per share the company currently held (split adjusted something like ~$2 per share when we bought). It hasn’t all been a bed of roses, we’ve made some not-so-great investments, but that’s a story for a different time :)
Edit: Paragraphs within bullets? How do you do them?

LakeBTC to Add EUR, GBP Trading – CEO Thomas Xie Interview by AllcoinsNews

allcoinsnews: My first question is about the history of LakeBTC. Who are the founders? You are in the Coinbase Big 4 index. What sort of volume do you do now in bitcoin (BTC)? How did you grow from the start? Have you raised venture capital?

Thomas Xie: LakeBTC was started in March 2013 as an exchange initially for a small group of traders and other financial professionals from investment banking and commercial banking sectors. These early users and investors helped shaped LakeBTC with their years of experience trading bonds, currencies, commodities, and all types of derivatives and structured products in financial markets.They know capital markets inside out, and they trade Bitcoins as a hobby, just like playing Texas hold’em. Later that year, we decided to incorporate and run the exchange under the current domain name. Naturally, our investors and many of the people we recruit have extensive financial experience, and this is one of the important differences than other players in the field. We are one of the big four bitcoin exchanges that determine CoinDesk BPI and a Gateway member of IRBA. We are also included in TeraExchange’s bitcoin index, which is the base of their US CFTC approved bitcoin swap, and our data is included in a number of leading bitcoin websites.
We are dedicated to building a fair Bitcoin platform with top security, excellent liquidity, and extraordinary customer service. As crypto currencies gained more and more exposures to the general public, LakeBTC is becoming a leading Bitcoin platform around the globe. Our years of risk management and internal control experience in financial industries build the most solid foundation for ensuring customers’ fund and privacy being safe and secure.
Additionally, creating a fair and efficient marketplace is also important to protect investors’ interests. We do everything in our power to minimize market manipulations and unfairness. Market surveillance programs, carefully designed products, comprehensive risk management, and strict internal controls are all meant to ensure this young and energetic market be fair and safe to every participant. At LakeBTC, users are best protected from financial predators, bitcoin theft, online fraud, market manipulators, trader errors, bot bugs, and flash crashes. We provide the same level of service to all users at all times. All users are treated with the same policy published on our website.
Trading volume really depends on the market conditions. It varies from a couple of thousand to over 10 thousand.
We have initial investors, but we have not raised any external funds yet. Some potential investors got in touch with us, and it’s ongoing.

allcoinsnews: You exchange offers USD / BTC trading now. I know that you will offer EUR / BTC trading very soon. When will this happen? What other services or currencies will you support in the near future?

Thomas Xie: To better serve our customers’ needs, we are constantly looking for banking and payment processing partners around the world. We added Ripple network and EgoPay, and we became a Gateway Member of International Ripple Business Association.
To better serve our European customers, we are finalizing partnership details with our payment processing partner in Europe, and plan to launch the service later this year. EUR and GBP will be included in the first phase, and multiple payment methods including SEPA will be added. It’d be much easier for Europeans to make deposits and withdrawals to/from LakeBTC at a much lower cost. With LakeBTC’s outstanding security, great liquidity, and superb customer service, we expect to see a sizable BTC/EUR trading activities.
We are also working with partners in North America, Africa, Southeast Asia, and South America to introduce more local payment methods and streamline the deposit/withdrawal processes.

allcoinsnews: How has the volatility of BTC affected your business planning?

Thomas Xie: Volatility definitely has an effect on market sentiment. Bitcoin is just a few years old, and this volatility is not surprising. As a matter of fact, when you look at the historical prices, what we see today is much smaller. On the bright side though, the volatility and the speculation help bitcoin stay on headline news and get more coverage from the media.
To any exchange, an effective market surveillance program is a critical component that ensures the fairness and smoothness of the marketplace. Unusual activities, abnormal positions, sudden price changes, and suspicious trades should raise alarms to exchange operators and if necessary, preventative actions should be taken quickly to mitigate the risk of price manipulations and human errors.
LakeBTC have a real time market surveillance program to monitor unusual trading activities and suspicious positions. By comparing with bitcoin index prices from other sources, we try to reduce the risk of market manipulations by individual attackers. This is especially important for a volatile market such as bitcoin. We shifted an enormous amount of effort into this, including market surveillance, limited orderbook, dark pool, product design, staff training and so on.
Other than that, we do plan to launch bitcoin derivatives such as futures to help miners, exchangers, merchants, and institutional investors to better manage their risks and exposures.

allcoinsnews: Your exchange is in English, Swedish, and Chinese. What is your analysis of what countries your users are from?

Thomas Xie: We have users from all around the world, with a better concentration from Americas, Europe and southeast Asia.
As mentioned earlier, we are adding banking and payment processors all around the world. Besides, we are currently working on adding more languages as well to bring better experiences to non English speaking users.
We offer a comprehensive and secure REST and Websocket API, with sample codes in PHP, Ruby, Python, and a few other programming languages. Professional algorithm traders would find it extremely easy to integrate their trading bots to LakeBTC. Our website design is responsive, and works equally well on mobile devices so casual users may buy and sell bitcoins on their cell phones smoothly.
We just made a major change to our fee structures, with maker-taker introduced and a big promotion is going on right now. Users may enjoy a 0.05% or even free trading at LakeBTC. All of these strategies will further grow our user base globally.

allcoinsnews: There have been some significant exchanges that have collapsed with hacking being an important factor (e.g. Mt Gox, Bitcoin Trader recently). How are you protecting your customers funds from this type of risk? In terms of wallets, what do you think is best solution for your customers?

Thomas Xie: The founder of Mt.Gox came from a technical background, but running a financial firm requires many years of risk management and internal control experience. That’s not something you can acquire overnight.
The safety of the wallet is indeed a huge challenge. Average users may choose and trust a professional bitcoin company such as LakeBTC, especially if it’s a lot of money. They should pick one who’s secure, legitimate, compliant, and well managed. Professional users who know what they are doing can manage their own wallets.
Security, liquidity and service are three strengths we have and security is number one. SSL encryption, cold storage, Google Authenticator, SMS confirmations, etc. are several technical measures we currently employ. But people have to realize that a Bitcoin exchange is not only a technology company, but more importantly, also a financial one.
If Facebook went under, it’s bad but people can live with it. Same thing for Amazon, Youtube, Uber and so on. But if your bank failed and all your savings vaporized? That’s horrifying.. A financial firm faces many security challenges that are unheard of typical technology companies. The technological security mechanisms mentioned above are certainly important, but what really matters to financial institutions are risk management and internal controls. Our team with years of experience in financial industries is working hard to ensure customers’ fund and privacy being safe and secure. For example, all withdrawals need to pass an automatic system checks for book balances, login history, trading patterns and so on, then passed to a two level manual approval process. If everything is good, the fund is transferred to the customer. We do everything in our power to minimize the risks of human errors, system bugs, and hacking activities. Incidents such as transaction malleability would not happen at LakeBTC.

allcoinsnews: Many governments have concerns (e.g. China, USA, etc..) about crypto currencies. How will the Chinese cryptocurrency develop going forward?

Thomas Xie: First of all, we are a BVI company, with customer service and technical support in Shanghai. LakeBTC is a bitcoin exchange for the world. We pay attention to the government policies around the world and do our best to stay compliant. We believe this is to the best interest of all our users.
Chinese government clearly stated that bitcoin is not a currency and would not regulate it as a currency. Secondly, the policy is in fact quite easy on bitcoin participants. The latest official policy declared that people have the right to own, buy, and sell bitcoin. The major goal of the existing policies is to manage risk and stop market manipulation. Margin and shorting trading, futures, and many other high-leverage products (20 times or even higher) and price manipulation caused flash crashes early this year and that’s the target of the so-called ban. If the situation does not improve, we are not surprised to see the policy tightens further and the entire bitcoin ecosystem is jeopardized.
US is more complicated. Both federal and state regulators are involved. The most recent NY DFS proposal is not considered a positive sign. We are living in the new millennium now and they government agencies need to adapt to the digital age too. It’s impractical and cumbersome for every state plus Fed to come up with a regulation each separately. Bitcoin is an internet thing and there’s no state borderline on the internet after all.

LakeTrader, a professional trading tool.

LakeBTC just launched our brand new trading tool, LakeTrader, earlier today. It is a in-browser trading app, with live data, pro charting, OnClick trade, and CoinDesk BPI data integrated.
![LakeTrader](https://www.lakebtc.com/assets/p3.jpg)
https://www.lakebtc.com/p/2644

Live Data

LakeTrader takes advantages of our latest websocket real time API. In a single web page, traders can view live orderbook data, trade history, open orders, and analyze historical trade data. As long as you are connected to our server, live data will be streamed to your browser in real time. Note that users can only view historical data after March 1, 2014, when a major database migration was carried out.

Pro Charting

We have integrated the charting lib by Trading View. There're loads of features available -- BTCUSD and BTCCNY charts in 1, 5, 15, 30, 60 minutes, 1 day, 1 week intervals with styles in bars, candle-stick, line, area, etc are provided. You can also draw trend lines, trend angles, pitchforks, gann box, fib retracement, ABCD patterns, Elliott Wave subminuette, and so on. For technical analysis, there are about 60 options to choose from, including MACD and others.
LakeBTC also integrated CoinDesk BPI (Bitcoin Price Index) data, an industry-leading index for bitcoin prcies. To switch to CoinDesk BPI, just click in the ticker box on the top left corner, type in any text, and select CDBPI:USD in the drop down. You will see the chart for 1 day and 1 week resolutions (you may want to swtich the chart type to "Line" for 1 day mode since OHLC prices are missing for each day). You may also compare LakeBTC USD chart with CoinDesk USD chart side by side.

OneClick Trade

Traders can place buy/sell orders by a single mouse click on the screen in our OneClick trade mode. Simply set a default order size (e.g., 0.2 BTC) and a multiplier (e.g., ×5), traders can hover his mouse over the Orderbook and an overlay with buy/sell buttons will appear with the corresponding price. Just click the button and the order will be sent to our server in real time. Once accepted, it will show up in the Open Orders pane in real time. This function is extremely easy to use and it's a great tool for all users, especially those trade frequently.
Or, if you prefer the old fashion trade entry, just click Manual tab, and you can fill in price and amount as you would normally do.
If your order got executed, it will disappear (or change in amount) in the Open Orders pane and show up in the Trade History pane, in real time. Note all numbers shown are before trading commission fees.
If you wish to cancel a single open order or all open orders, it's also as easy as a mouse click and the page will update accordingly.
To summarize, LakeTrader is a full feature real time trading application in your browser -- there's nothing to download and install on your local machine. LakeTrader is still in beta, bug reports/comments/criticisms can be sent to [email protected]
