Cryptocurrencies are decentralized digital assets that use blockchain technology to ensure security and transparency in transactions. Unlike traditional money, they are not controlled by banks or governments, but by a distributed network of computers.

Bitcoin, created in 2009, was the first cryptocurrency and remains the most popular, although there are thousands of alternatives like Ethereum, Litecoin, and Cardano. Its value fluctuates according to supply and demand, which makes them attractive to investors and speculators.

Cryptocurrencies can be used for payments, investment, and smart contracts. However, they also face challenges such as regulation, volatility, and security. Their adoption continues to grow globally.
