I deposited some coins that are linked to eXch (I didn't even use it myself, it's like 2 people back) to an exchange and my account was frozen as a result. What can be done to lower the risk score of coins from eXch? My coins are not from illegal activity and I don't want to do anything illegal.
First, swap them on another no-KYC exchange, and only after that, send them to CEX, where there is a risk of freezing funds.
There are several instant exchangers that, before any transaction, will check the AML score of the coins you want to swap and confirm whether it is safe to use their service.
Or use mixer
I have used my coins exch in those exchanges . I always send money in small batches
Swapuz.com (they accepeted some coins, then refunded me without kyc agter a few batches)
