Like a traditional ATM, a Bitcoin ATM has a monitor, a QR scanner, a bill acceptor and a dispenser. To try here connect their Bitcoin wallet to a crypto ATM, users are usually prompted to scan a QR code corresponding to their BTC wallet address. It’s simple to buy Bitcoin for the best price on OKX. If you’re a beginner with no cryptocurrency holdings, you can use your credit card or other payment methods — such as Google Pay or PayPal — to buy Bitcoin on OKX with your national currency. With its recent integration with Paxful, OKX supports more than 160 fiat currencies, including the U.S. dollar, euro, Indian rupee, Brazilian real and more. Unlike traditional currency, bitcoin is created, distributed, traded, and stored within a decentralized ledger system known as blockchain. Think of a blockchain like a giant spreadsheet that records every bitcoin transaction, ever — only it’s super secure and anonymous.
