$BTC
Bitcoin is a digital currency built on blockchain technology, enabling peer-to-peer transactions on a decentralized network without the need for central authorities like banks or governments. It is created through a process called mining, where powerful computers solve complex mathematical problems to validate and secure transactions. Miners are rewarded with newly created Bitcoin for their work. However, investing in Bitcoin carries significant risk due to its highly volatile nature, with prices subject to dramatic fluctuations over short periods.
