What is Bitcoin

Cryptocurrency is a digital or virtual currency that uses cryptography for security and is decentralized, meaning it's not controlled by any government or financial institution. Transactions are recorded on a public ledger called a blockchain, which helps to secure and verify the transactions. Cryptocurrencies like Bitcoin, Ethereum, and others have gained popularity for their potential to provide fast, secure, and low-cost transactions, as well as their potential for investment and speculation.
