How to avoid withdrawal risks in the cryptocurrency circle:

1. Choose large OTC trading platforms, such as Binance and Ouyi, which have good communication with regulatory authorities and can better avoid risks.

2. Prefer OTC platforms that support T+1 or T+2 withdrawals. Although you need to wait for a while to withdraw cash, it can reduce the risk of money laundering. Such as Binance T+1 withdrawals and Huobi's strict selection transactions (T+2).

3. Try to avoid stable currency OTC transactions such as USDT, and use mainstream digital assets such as BTC and ETH instead.

4. OTC transactions use special bank cards, which are separated from accounts such as wages, to facilitate the explanation of fund flows.

5. Choose cards from local banks to avoid the accounts of large national banks that are easily frozen.

6. Be cautious about frequent transactions. Multiple indirect transactions by the same user on the same day may arouse suspicion.

7. Find reputable OTC merchants to cooperate with and avoid frequent transactions with unknown merchants.

8. Reduce the frequency of withdrawals and appropriately increase the amount of cash conversion per time.

9. Do not transfer to other bank cards after OTC. You can choose to withdraw cash from ATM or spend online.

10. Try to choose normal working hours for trading.

11. After selling USDT, do not rush to transfer it out for the time being. Keep it in the account for a while.

Once the account is frozen, you can take the following measures:

1. Understand the reason for the freeze, whether it is bank risk control or public security judicial freeze.

2. Bank risk control freeze can provide transaction flow and other proofs, public security freeze needs to cooperate with the police investigation.

3. If it is a public security freeze, observe whether it is turned into a formal freeze for 3 days, and then contact the responsible police.

4. After verifying that you have no illegal behavior, you can cooperate with the investigation to unfreeze.

In short, OTC transactions need to be cautious. Once the account is frozen, you don’t have to worry too much. You need to know that individuals engage in digital asset transactions and do not violate the law. Try to save every transaction record, chat record, on-chain transfer record, etc., and cooperate with problems when they arise!
