Cryptocurrency: key concepts for beginners

Cryptocurrency is a digital form of money that uses cryptography to secure transactions. The main principles of cryptocurrency are decentralization, anonymity, and security. Unlike traditional currencies, cryptocurrencies are not controlled by government institutions. The most popular are Bitcoin and Ethereum, but there are many other coins, each with its own features. An important aspect is the blockchain technology, which cryptocurrencies are based on, ensuring transparency and the impossibility of altering records.
