Cryptocurrencies explained

What are cryptocurrencies?

Cryptocurrencies are digital or virtual currencies that use cryptography for secure financial transactions. They operate on a decentralized network, meaning that they are not controlled by any central authority or government.

The decentralized nature of the blockchain means that it is not controlled by any single entity, making it resistant to fraud and tampering. Transactions on the blockchain are also secured through the use of complex mathematical algorithms and cryptographic techniques.

Cryptocurrencies can be used for a variety of purposes, including making purchases online, sending money to friends and family, and as an investment. Some merchants and businesses accept cryptocurrencies as a form of payment, although their use is still relatively limited compared to traditional currencies.
