I'll write about crypto and money in a few sentences in English. However, please note that I'll be translating it into Simplified Chinese for you.

Cryptocurrencies such as Bitcoin and Ethereum have gained popularity in recent years as an alternative form of digital money. They are decentralized, meaning they are not controlled by any government or institution, and transactions are recorded on a public ledger called a blockchain. This lack of centralized control has led to concerns about the volatility and security of these currencies. Meanwhile, traditional fiat currencies like the US dollar and euro are issued and regulated by central banks and governments, providing a sense of stability and trust.
