#CryptoMarketWatch A cryptocurrency is a type of digital money that uses blockchain technology to ensure security and decentralization. Unlike traditional money, it does not rely on banks or governments, but on a global network of computers that verify and record transactions. Bitcoin, created in 2009, was the first cryptocurrency and remains the most popular. Others, like Ethereum, allow for the execution of smart contracts. Cryptos are highly volatile and can be used for investment, payments, or quick transfers. However, their regulation varies by country, and their adoption is still growing, generating debates about their impact on the global economy.
