Bitcoin Price Index
The CoinDesk Bitcoin Price Index (CoinDesk BPI) was launched in September 2013. The Bitcoin Price Index is an average of bitcoin prices across bitcoin exchanges, and began by using price data from Bitstamp, BTC-E and CampBX. Although Mt. Gox data was not used initially, due to withdrawal concerns for US customers, in November 2013, Mt. Gox was added to the BPI due to "a reduction in the risk premium and the option of additional deposit/withdrawal methods". The Mt. Gox bitcoin exchange was eventually removed from the index in February 2014 after its "persistent failure to meet the index's standards for inclusion".
The index was restored to an average of three exchanges in March 2014 with the inclusion of Bitfinex bolded per BOLD "terms that are redirected to the article or its sub-sections", since the redirect for Bitfinex is pointed at this article. price data, according to CoinDesk: "Since the decline of Mt. Gox, we have observed that Bitfinex has been able to sustain a dramatic increase in its share of the total volume of U.S. dollar-denominated bitcoins traded”.
Publications which have referenced the Bitcoin Price Index data or price include the BBC, Reuters, NY Times, CNBC and Bloomberg.
CoinDesk launched a proprietary Bitcoin Price Index on September 11, 2013. The Bitcoin Price Index (BPI) represents an average of bitcoin prices across leading global exchanges that meet criteria specifed by the BPI. It is intended to serve as a standard retail price reference for industry participants and accounting professionals.
Criteria for inclusion in the BPI are:
- Exchange must serve an international customer base;
- Exchange must provide a bid-offer spread for an immediate sale (offer) and an immediate purchase (bid);
- Minimum trade size must be less than 1,500 USD or equivalent;
- Daily trading volume must meet minimum acceptable levels as determined by CoinDesk;
- Banking transfers in or out of the exchange must be completed within seven business days.
Upon launch, BitStamp, BTC-E and CampBX met these criteria and were included in the index.
The main features of the index are as follows:
- The CoinDesk BPI is a simple average of leading XBT/USD exchange prices;
- The BPI is expressed as the midpoint of bid/ask spread;
- The BPI is updated every 60 seconds;
- If an exchange does not update its price for more than 30 minutes, it is omitted from the live BPI calculation until it is updated again;
- New index historical data commences on 1 July 2013;
- Prior index historical data is obtained via Mt. Gox;
- End-of-day high, low, and closing BPI is based on Greenwich Mean Time (GMT) or British Summer Time (BST) when appropriate;
- Non-USD BPI prices are implied based on rates obtained via openexchangerates.org;
The CoinDesk BPI is now used by the Bitcoin Foundation, Bitcoin Insider and several charting platforms. A free API is available for developers.

State of Bitcoin report
In February 2014, CoinDesk released its first 'State of Bitcoin' report. The aim of the report is "to provide an overview of key cryptocurrency trends, challenges, and opportunities, while also highlighting the most important developments over the last year”. A follow-up report in Q2 2014 highlighted that venture capital investment in bitcoin companies was up 28 percent compared to the previous quarter, and that VC investment was pouring into European Bitcoin startups.
CoinDesk Information Centre
On August 21st 2013, CoinDesk launched a bitcoin information centre. This contained guides on everything from the very basics of digital currency to how to set up your own bitcoin mining rig.
In April 2014, CoinDesk released an iOS app. The app includes news stories and editorials, as well as its 'Bitcoin Price Index'.
This London-based resource and news operation aims to be the “Reuters of Bitcoin” according to its founder Shakil Khan. As an angel investor in Spotify and bitcoin startup BitPay, Khan noticed a gap in the news coverage for bitcoin and digital currencies in general when other entrepreneurs constantly questioned him about bitcoin. CoinDesk was launched on May 1st 2013. In September 2013, Jon Matonis, executive director of the Bitcoin Foundation joined CoinDesk as a contributing editor.
