1 Not only withdrawals are at risk, but deposits can also lead to card freezes. As long as the other party's (merchant's) account is involved in fraud, if you transfer money to them, your card may also be frozen.

2 If your deposit is frozen, whether it is local or from a different region, if the police call you to go there, you can go. Honestly explain that you are just trading cryptocurrencies. If they tell you to stop, just agree, and generally, there won't be any issues. If you don't go, they might report your information to the anti-fraud system, causing all your cards to be frozen.

3. If your withdrawal is frozen, it depends on the situation. If the local police call you to go, you can go. If you don't go, they may come to arrest you; since it's local, there won't be budget issues. If you go, and they ask you to return the stolen goods, just do it. Once you return it, the officer's job is done, and they won't make things difficult for you. Don't say things like 'I am also a victim'; such statements may make the officer feel you are complicating their work, and there's a high probability they will take action against you, possibly reporting you to the anti-fraud system, leading to all your cards being frozen. If the police from another region call you to go, first call them to ask about the situation, explain that you are just trading cryptocurrencies and received dirty money unknowingly. You can cooperate to return the stolen goods and ask what you need to do, and if it's possible to provide information remotely. If they insist you must go, definitely do not go. It may just be a case that requires funding for investigation from a different location, so it’s not worth traveling for it. But if you go, they may take immediate action against you.

4 Do not seek merchants for deposits and withdrawals; merchants are essentially just like prostitutes. Seeking deposits and withdrawals from merchants is akin to seeking prostitutes, with a high risk of sexually transmitted diseases.
