Bitcoin (as a contrast)

Bitcoin is a digital form of money that operates without a central authority like a bank or government. It uses blockchain technology—a secure, transparent ledger shared across many computers—to record transactions. This decentralized system ensures that transactions are verifiable and tamper-proof, reducing reliance on traditional financial institutions. Bitcoin can be used for online payments, investments, or transferring value globally. Its supply is capped at 21 million coins, making it resistant to inflation. Unlike conventional currencies, Bitcoin exists purely electronically, offering a peer-to-peer alternative for financial transactions.
