#CryptoSecurity101 Bitcoin (BTC) is a decentralized digital currency that has revolutionized the world of finance. It operates independently of central banks and governments and relies on blockchain technology to record transactions securely and transparently.

Bitcoin is characterized by several key features: enhanced security through cryptography, transparency as all transactions are public, and a limited supply of only 21 million coins, which contributes to its potential long-term value. Bitcoin provides the possibility of reducing transaction costs and increasing financial freedom for individuals, but it experiences significant price volatility, making it a high-risk investment. It is seen as a potential future for global payments and a store of value.
