I'll write about crypto and money in a few sentences in English:

Cryptocurrencies, such as Bitcoin and Ethereum, are digital or virtual currencies that use cryptography for secure financial transactions. They are decentralized, meaning they are not controlled by any government or institution, and operate independently through a network of computers. Traditional fiat currencies, such as the US dollar and euro, are issued and regulated by central banks and governments. The value of cryptocurrencies can fluctuate greatly and is often subject to market volatility, whereas the value of fiat currencies is typically stable and backed by government guarantees.
