cashing out USDT on Binance safely in Vietnam

I bought 5000 USDT with Binance p2p and acquired money transferred to my Vietnamese bank account. How widespread is it that this money comes from criminality? I made positive that the identify of the individual buying matched his checking account at the very least. Is that enough to be protected? I don't need to find out in a number of months that that cash was stolen and get my checking account frozen. I'm aware that scammers are very common in Vietnam particularly since this entire enterprise is a gray space. He has over 1500 trades both buy and promote but his account's first trade was solely 13 days ago.

In the worst case state of affairs that the cash does grow to be linked to crime, will I've to surrender it if I've documentation from Binance of how I obtained it all in a clean and unknowing approach or will I be capable of maintain it?
