This both serves as a buyer beware and a need for advice.
TLDR: I sold XMR for BTC on bisq, transferred it to 2 different exchanges and both accounts independently got locked in the past 2 months.
Before I hear that I should stay away from exchanges, I know, I know already. It is only a small portion of what I own but I like doing high frequency small trades which is not possible on bisq at the moment due to the mining cost being more than the amounts I want to trade so it is a necessary evil.
The first exchange was poloniex, which out of the blue just stopped my withdrawals. When I opened tickets all they will tell me is that my trading “looks suspicious” and needs a person to approve it. They will give no information and are not asking me for any information but just keep giving me that empty response. It has been 60 days.
Second exchange is Bitfinex this week, they also stopped withdrawals and also all trading, and they too responded with a generic you look suspicious but they are now asking for KYC info, like way to much information kind of questions like tax forms, passports, all previous transactions, my owned addresses, and TXs from all wallets/exchanges and view keys from my monero wallets.
Surely looks like I’ve picked up tainted BTC from bisq. The 2 accounts are not linked to each other in any way and have never had coins transferred between them. I think this is very serious for the community. I have done 1000+ trades on bisq but I will never again if the coins I get are labeled as suspicious and are not able to be used and get investigated like this.
Also if anyone has advice on how to deal with the exchanges and if I should be bending to their every questions to get my coins back please PM me.
edit - also bisq is the only incoming source for both of these accounts
