The choice to forgo RMB to store cryptocurrencies such as USDT, BTC, BNB and ETH may be based on the following considerations:

1. investment diversification: cryptocurrencies offer a means of investing differently from traditional currencies and assets, allowing users to diversify risk and potentially earn high returns.

2. Doubts about the traditional financial system: Cryptocurrencies offer an alternative means of storing value and transactions for those worried about inflation, currency devaluation or risk to the banking system.

3. Global access and liquidity: Cryptocurrencies can be traded globally, providing the convenience of cross-border transactions and remittances, especially in regions where capital flows are restricted or stable financial infrastructure is lacking.

4. Technological advantages and potential for innovation: Innovations in blockchain technology bring increased transparency, efficiency and security to financial transactions. Cryptocurrencies are also able to support smart contracts, decentralized applications (DApps) and emerging financial services.

5. privacy and anonymity: while the level of privacy varies, many cryptocurrencies offer more anonymity and privacy protection than traditional banking systems.

6. views on the future of cryptocurrencies: some believe that cryptocurrencies represent the future of money and that the choice to invest or hold is an early adaptation to emerging economic and technological trends.
