$BTC Bitcoin (BTC) is the original decentralized digital currency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a peer-to-peer network, meaning transactions occur directly between users without the need for intermediaries like banks or governments.

At its core, Bitcoin utilizes blockchain technology – a public, distributed ledger that securely records all transactions. This system is maintained by a global network of "miners" who validate transactions and add them to the blockchain, earning new bitcoins as a reward. Bitcoin's finite supply of 21 million coins contributes to its appeal as a potential store of value and an alternative to traditional financial systems.
