From which amount did your bank retained your money and asked you to supply additional documents etc? 10K+? 100K+? they never retained your amount? Planning to book partial profits and want to know others experience.
Even before opening a bank account, usually, you have to provide all your details so it doesn't make sense how one can avoid KYC if using real banks. Are you talking about VBA? (Virtual Bank Account)
Yes if you are transacting huge amounts or the account isn't active but suddenly a lot of funds are being poured into it, then there might be additional scrutiny but that won't happen in VBA if you are using a good one.
I won't suggest doing any illegal activities through your own bank accounts if even do them at all via any source because I have seen some adverse things happening to users in past. There used to be a LBC user whom I knew was a legit seller, legit in the sense that he was trusted, but he was somehow involved in money laundering and faced more issues within the case than most of us would face in our entire life. So make sure what you are doing is legal since it involves your bank accounts.
