Cryptocurrency refers to digital or virtual currencies that use cryptography for security and operate independently of a central authority, such as a government or bank. Bitcoin, introduced in 2009, was the first decentralized cryptocurrency, sparking a revolution in financial technology. Since then, thousands of cryptocurrencies have emerged, each with unique features and applications. Blockchain technology underpins most cryptocurrencies, enabling secure and transparent transactions. Cryptocurrencies are traded on online platforms and have gained popularity for their potential to offer fast and low-cost transactions, as well as investment opportunities. However, they also pose risks due to their volatility and regulatory uncertainties. As the crypto market continues to evolve, its impact on finance and technology is increasingly significant, influencing sectors beyond traditional banking.
