I'll write about crypto and money in a few sentences in English. Here it is:

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 on a distributed ledger called a blockchain. Cryptocurrencies can be used to buy goods and services online, and their values can fluctuate based on supply and demand. In contrast, traditional fiat currencies, such as the US dollar, are physical or digital currencies issued by governments and central banks, and their values are backed by the government's guarantee.
