$ETH Cryptocurrency is a digital asset that uses blockchain technology for secure transactions. Unlike traditional currencies, crypto operates without a central authority, making it decentralized. Bitcoin, the first cryptocurrency, was created in 2009 by Satoshi Nakamoto. Since then, thousands of cryptocurrencies, like Ethereum, Binance Coin, and Solana, have emerged. Crypto is used for trading, investing, and even online purchases. Prices are highly volatile, influenced by market demand, news, and regulations. Many traders use technical and fundamental analysis to predict price movements. While crypto offers high profit potential, it also carries risks. Proper knowledge and strategy are essential for success in trading.
