Bitcoin is a decentralized digital currency, created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. Unlike traditional currencies issued by central banks, Bitcoin operates on a peer-to-peer network using a technology called blockchain. Transactions are recorded on this public, distributed ledger and secured using cryptography. Bitcoins can be exchanged for other currencies, goods, and services. Its value fluctuates based on supply, demand, and market sentiment. Bitcoin's finite supply of 21 million coins aims to make it a store of value, while its decentralized nature offers an alternative to traditional financial systems.
