If you make a significant amount of money in cryptocurrency and try to withdraw it in cash, banks will likely inquire about the source of the funds, especially if it's a large sum like 100 million. For example, if you consistently sell USDT (U) and accumulate around 5 million in your account without withdrawing, the bank may contact you, possibly offering financial services like insurance, trusts, or VIP accounts.

When selling USDT on platforms, you risk dealing with "black money" (illegally obtained funds). If you encounter third-level black money and it’s not a huge amount, your account might get frozen for a few days. But with large sums, your account could be frozen for months. Second-level black money could lead to a six-month freeze or even confiscation, and in some cases, authorities may pursue legal action. If the amount is smaller, a 10% compensation might resolve the issue, but with larger sums, the consequences could be more severe, including jail time and restrictions on financial activities for five years.

If you're selling USDT at unusual prices, for instance, selling for 7.5 yuan when the market rate is 7 yuan, you could be suspected of illegal activities. It’s essential to avoid buying or selling USDT at suspiciously high or low rates, as this could lead to charges related to concealing illicit funds.

To avoid legal risks, it’s advised not to use platforms or deal with unknown merchants for selling USDT. Cash transactions are especially risky, as they may involve black money or even put your personal safety in danger.

If you’ve made a lot of money and want to withdraw it, a safer approach is to work with someone you trust. Typically, they would give you the money first, and you would transfer the USDT after verifying the funds. It's important to avoid taking money from accounts with frequent suspicious transactions or ones where the funds haven’t been deposited for at least three days. Stick to normal, personal-use accounts.$BTC @dappOS_com
