Bitcoin work
Bitcoin (BTC) is a cryptocurrency, a virtual currency designed to act as money and a form of payment outside the control of any one person, group, or entity, thus removing the need for third-party involvement in financial transactions. It is rewarded to blockchain miners for verifying transactions and can be purchased on several exchanges.
Bitcoin was introduced to the public in 2009 by an anonymous developer or group of developers using the name Satoshi Nakamoto.

It has since become the most well-known cryptocurrency in the world. Its popularity has inspired the development of many other cryptocurrencies. These competitors either attempt to replace it as a payment system or are used as utility or security tokens in other blockchains and emerging financial technologies.

KEY TAKEAWAYS
Launched in 2009, Bitcoin is the world's largest cryptocurrency by market capitalization.
Unlike fiat currency, Bitcoin is created, distributed, traded, and stored using a decentralized ledger system known as a blockchain.
Bitcoin and its ledger are secured by proof-of-work (PoW) consensus, which also secures the system and verifies transactions.
Bitcoin can be purchased via various cryptocurrency exchanges.
Bitcoin's history as a store of value has been turbulent; it has undergone several boom and bust cycles over its relatively short lifespan.
