BTC stands for Bitcoin, which is a digital or cryptocurrency. Bitcoin operates on a decentralized peer-to-peer network, enabling secure and transparent transactions without the need for a central authority like a bank. It uses blockchain technology to record and verify transactions, and its native unit of currency is also called Bitcoin, abbreviated as BTC. Bitcoin is known for its limited supply (capped at 21 million coins), divisibility, and the concept of mining, where participants use powerful computers to solve complex mathematical problems to validate transactions and create new bitcoins.
