Bitcoin is the most well-known longest-running cryptocurrency, released initially as an open source in 2009 by Satoshi Nakamoto. Bitcoin is a decentralized medium of digital exchange, with transactions recorded and verified in a public distributed ledger (the blockchain) without the need for a record-keeping authority or central intermediary.

Transaction blocks contain an SHA-256 cryptographic hash of previous transaction blocks and are thus "chained" together, serving as an immutable record of all transactions that have ever occurred. As with any currency/commodity on the market, bitcoin trading and financial instruments soon followed the public adoption of bitcoin and continue to grow. Included here are historical bitcoin market data at 1-min intervals for select bitcoin exchanges where trading takes place. Happy (data) mining!
