If you don't even know what the cryptocurrency world is, what you are doing, and what the risks of withdrawing funds are, please don't come to the cryptocurrency world to give yourself away. There are 108 ways to make your sewing machine smoke.
Uncle will not give you a discount just because you are a college student, nor will he let you off the hook just because you don't understand.
As for the status of the cryptocurrency world in China and what behaviors may lead to imprisonment, I won't say much.
For withdrawals, let's talk about a few points:
1. Don't take chances. Withdrawing 100 yuan is the same as 1 million yuan, and the probability of having your card frozen is the same (one hand of black money, freezing all cards).
2. The fewer withdrawals, the lower the risk. My personal suggestion is to withdraw once per cycle, so invest with spare money.
3. Keep a low profile. Don't tell anyone how much assets you have, especially U merchants. As for why, I can't say more.
