Bitcoin

Bitcoin was the first cryptocurrency to ever be created. It’s an open-source, decentralized, peer-to-peer cryptocurrency created by Satoshi Nakamoto, an unknown person or group, who first introduced BTC (or XBT) to the world through an email sent to a cryptography mailing list .

It functions without a central bank or centralized administrator, and its transactions are semi-anonymous. New bitcoins are introduced to the market through a mining process, which rewards those that secure the network through what’s known as a proof-of-work (PoW) consensus algorithm.

Bitcoin’s maximum supply is capped at 21 million, and the very last BTC is expected to be mined in 2140.
