$BTC

Bitcoin relies on the blockchain, secured by proof of work (PoW) and cryptographic hashing (SHA256). Miners validate transactions, making attacks costly (51% attack). Users must protect their private keys through secure wallets (ColdWallets like Ledger/Trezor). Beware of Scams, Phishing, and unregulated exchanges. Decentralization limits censorship risks. However, software bugs (e.g., MtGox) and regulations threaten its stability. HODL safely! Crypto BTC
