It is recommended that everyone keep some USDT on hand.

The introduction of regulations related to stablecoins is quietly changing the global financial landscape. A typical example is that "coin-stock trading" has begun to take shape, meaning that holders of stablecoins can now directly participate in the global stock market, no longer restricted by traditional account opening processes and national limitations.
This is a huge challenge for some countries. Especially when there are not many investment channels in the country, such as insufficient attractiveness of real estate and the stock market, funds will naturally seek new outlets. We can already see this trend, for example, Hong Kong Stock Connect and overseas ETFs often appear at a premium, indicating that investors have a very strong interest in external markets.
To prevent excessive outflow of funds, regulators have started to take action—many overseas brokers such as Futu and Tiger have had their account opening permissions revoked, which is blocking the "traditional channels." However, now, the stablecoin + crypto-stock combination has reopened a new channel: as long as you hold stablecoins like USDT, you can "bypass local restrictions and invest in global markets."
The problem is that the essence of stablecoins is actually the US dollar, and this path will lead to a large outflow of foreign exchange. This is difficult for regulators to accept, so it can be anticipated that there may be stricter restrictions on aspects such as "CNY to stablecoin" in C2C and OTC transactions, or even a complete blocking of related entry points.
Therefore, before the current policies are fully tightened, preparing a certain proportion of stablecoin reserves for oneself is a way to hedge against risks. Once this path is completely closed in the future, exchanging for USD will only be possible through bank channels, which are limited to an annual quota of $50,000, and the procedures are complicated and inefficient.
The window of opportunity will not always exist. Make some reservations and prepare in advance; it's much more relaxed than scrambling at the last minute.
