BTC is an abbreviation for Bitcoin, which is a type of digital currency that uses cryptography to secure and verify transactions as well as to control the creation of new units. Bitcoin was created in 2009 by an unknown individual or group using the pseudonym Satoshi Nakamoto.
Bitcoin operates on a decentralized, peer-to-peer network, meaning that transactions are verified by a network of nodes rather than a central authority. The total number of bitcoins that can be created is limited to 21 million, and new bitcoins are created through a process called mining, which involves solving complex mathematical equations.
Bitcoin has gained popularity as a form of digital currency that allows for fast, low-cost, and borderless transactions. It has also been subject to significant price volatility and has been the subject of controversy due to its association with illicit activities on the dark web and concerns about its environmental impact due to the energy consumption required for mining.
