#ArbitrageTradingStrategy Cryptocurrency is a form of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments (like dollars or rupees), cryptocurrencies are decentralized and operate on blockchain technology. This means that transactions are recorded in a public ledger that is maintained by a network of computers (called nodes), ensuring transparency and security. Bitcoin was the first cryptocurrency, introduced in 2009, and since then, thousands of others like Ethereum, Binance Coin, and Solana have emerged. People use cryptocurrencies for online transactions, trading, and even as an investment. Although the value of cryptocurrencies can be very volatile, their popularity is growing worldwide due to the promise of financial freedom, fast transactions, and lower fees. However, risks like scams, lack of regulation, and hacking still exist, so users must be careful.
