Bitcoin is a decentralized digital currency created in 2009 by Satoshi Nakamoto.
It operates without a central authority like a bank or government.
Transactions are verified by network nodes through cryptography.
It is based on a public ledger called the blockchain.
Bitcoin is often referred to as digital gold due to its limited supply.
Only 21 million bitcoins can ever exist, ensuring scarcity.
Current market price: ~$62,500 per BTC (as of June 2025).
