What is Bitcoin (BTC)?
Share
Overview
Bitcoin is the first decentralized cryptocurrency, created by Satoshi Nakamoto in 2009. It operates on a P2P network without a central authority, ensuring transparency and security through blockchain technology. With a maximum supply of 21 million coins, it is often called Digital Gold.
How It Works
Bitcoin uses a Proof of Work consensus mechanism. Miners solve complex mathematical problems to create new blocks and validate transactions. Approximately every 4 years, a halving event reduces mining rewards by half, increasing scarcity.
