$USDC Bitcoin is a decentralized digital currency created in 2009 by an unknown person using the alias Satoshi Nakamoto. Unlike traditional money, Bitcoin operates without a central bank or government. Transactions are verified by network nodes through cryptography and recorded on a public ledger called the blockchain. Bitcoin is limited in supply, with only 21 million coins that can ever exist, making it scarce and potentially valuable. It can be used for purchases, investment, or transferring funds globally. However, its price is highly volatile. Bitcoin has sparked both excitement and debate as it challenges the traditional financial system and introduces new possibilities.
