Bitcoin (BTC) is a decentralized cryptocurrency created in 2009 by Satoshi Nakamoto (unknown identity). Based on blockchain (a secure public ledger), it allows peer-to-peer transactions without intermediaries (banks). Bitcoins are generated through mining (computational calculations validating transactions). Their number is limited to 21 million, making it a rare asset. Used as a store of value (digital gold) or means of payment, its price is very volatile. Bitcoin is anonymous, transparent, and resistant to censorship, but criticized for its ecological impact (energy consumption).🚀
