$BNB What are cryptocurrencies and how do they work? 🤔
Cryptocurrencies are digital currencies that are based on blockchain technology to guarantee their security, transparency and decentralization. The blockchain is a distributed ledger system that stores transactions in an encrypted form and verified by a network of nodes. Each cryptocurrency has its own blockchain, which is constantly updated with new blocks containing the operations carried out. Some of the most popular cryptocurrencies are bitcoin, ethereum, litecoin, ripple and dogecoin. These currencies can be used to buy goods and services, invest, speculate or send money anywhere in the world without intermediaries or commissions.
