Is it considered a crime of having a huge amount of assets with unknown sources after earning 10 million yuan through cryptocurrency trading? To be clear to you, there are currently no judgment cases for the crime of unclear source of assets. Only you can land as An is yours. The most common situation where you encounter black money when withdrawing funds may be the crime of aiding and abetting trust. Other situations are also not encountered by ordinary retail investors, so there is no need to worry. But this premise is that you have received black money from others. Yes, so far policies have been cracking down on virtual currencies in mainland China, including the People's Bank of China, but so far there is no legal provision that makes speculation illegal. All the 'coin speculation caught' you see now are either due to selling USDT indiscriminately and receiving black money, or due to personal uncleanliness. As long as you have obtained wealth through legitimate cryptocurrency trading and have a record of USDT sources, you are not afraid. You only need to do some bank card risk control and screen legitimate and reliable merchants
