#WYSTStablecoin Cryptocurrency is a digital or virtual form of money that uses cryptography for security, making it decentralized and resistant to counterfeiting. Unlike traditional currencies controlled by governments and banks, cryptocurrencies operate on blockchain technology, a distributed ledger that records all transactions transparently. Bitcoin, created in 2009 by Satoshi Nakamoto, was the first cryptocurrency and remains the most popular. Since then, thousands of cryptocurrencies have emerged, including Ethereum, Binance Coin, and Solana, each with unique features. Crypto enables fast, low-cost transactions worldwide, but it also faces challenges like volatility, regulation, and security risks. Its future depends on adoption and innovation.
