$BTC Bitcoin (BTC) is the world's first and most popular cryptocurrency, powered by blockchain technology. One of its biggest advantages is decentralization, meaning it is not controlled by any government or bank. Transactions with Bitcoin are fast and secure, making it far ahead of traditional banking systems. Due to its limited supply (only 21 million coins), it has become a valuable digital asset. Bitcoin is often used as a store of value, and many people refer to it as digital gold. It is also easily transferable worldwide, making international transactions more convenient. Through Bitcoin, people can achieve personal financial freedom and take control of their own money.
