#MyTradingStyle Cryptocurrency is a form of digital currency based on blockchain technology, a decentralized and secure ledger. Unlike traditional currencies, it is not controlled by a central bank. Bitcoin, created in 2009, is the first cryptocurrency. Since then, thousands of others like Ethereum, Solana, or BNB have emerged. Each transaction is verified by a network of computers, ensuring transparency and security. Cryptos can be used for investing, trading, or accessing decentralized services (DeFi, NFT). To start, it is essential to understand digital wallets, private keys, and security. Always do your own research before investing.
