Bitcoin works like a digital asset which has a unique code that is encrypted and can be used for secure, fast, and low-fee transactions. The code functions as a sort of digital key and is stored in digital wallets. When someone wants to make a purchase, they send this code to the store to access the necessary funds. All transactions are recorded on the blockchain ledger, providing a high degree of security. Furthermore, Bitcoin transactions are almost instant and the fees for using Bitcoin are very low compared to traditional payment methods.
