$BTC Bitcoin, the first decentralized cryptocurrency, operates on a technology called blockchain. Created in 2009 by Satoshi Nakamoto, its supply is limited to 21 million coins, aiming for scarcity. Periodic "halvings" reduce the reward for mining blocks, impacting its inflation rate.

With a market capitalization exceeding $2 trillion, BTC is the dominant cryptocurrency. Its price has experienced significant volatility, reaching historical highs near $109,000 USD in 2025.

Bitcoin is used for value transfers, investment, and, to a lesser extent, for purchases. Its decentralized nature offers resistance to censorship and potentially lower fees in cross-border transactions. Regulation varies globally, with some countries adopting it and others restricting it.
