Bitcoin is the first and most widely recognized cryptocurrency, introduced in 2009 by an anonymous person or group under the pseudonym Satoshi Nakamoto. It was designed as a decentralized digital currency, meaning it does not rely on banks, governments, or traditional financial institutions to operate. Instead, Bitcoin transactions are recorded and verified through blockchain technology, which functions as a secure, public digital ledger that anyone can access but no single entity controls.
One of Bitcoin’s defining features is its limited supply. Only 21 million bitcoins will ever exist, making it scarce like gold. This scarcity contributes to its value, as demand often exceeds the limited supply. Over the years, Bitcoin has become not only a digital currency used for online transactions but also a popular investment asset. Some people use it to make payments, while others view it as a store of value or a hedge against inflation.
However, Bitcoin is highly volatile. Its price can rise or fall dramatically in short periods, making it attractive to speculators but risky for cautious investors. Despite this, Bitcoin has influenced the development of thousands of other cryptocurrencies and has sparked global discussions about the future of money, digital finance, and decentralized economies.
