#USChinaTradeTalks Cryptocurrency is a form of digital or virtual currency that uses cryptography for security. Unlike traditional currencies issued by governments, cryptocurrencies operate on decentralized networks based on blockchain technology. Bitcoin, created in 2009, was the first and remains the most well-known. Since then, thousands of alternative cryptocurrencies—such as Ethereum, Solana, and Cardano—have emerged. These digital assets enable fast, borderless transactions and have become popular for investing and trading. However, they also face challenges like regulatory scrutiny, price volatility, and security concerns. Despite these risks, crypto continues to evolve, shaping the future of finance and technology.
