Here is the list of exchanges which can ban you and confiscate your funds at any moment:
- All centralized exchanges
They
can, sure. But I'd like to know and make visible to everyone which are either openly against fungibility / mixing and condone it officially or where many users have reported such issues in the past.
Even so, it's worth to mention any centralized exchange are likely reject certain address/coin.
At any time, for any reason, we may have a problem with any centralized exchange.
This is why we should always send our coins in batches to exchanges.
I have made some big sells in binance last years when we reached ath. I was afraid they could reflect my funds, so I send in 3-4 transactions. Only after the fiat withdrawal I made the next btc transaction.
No problems, and there were some mixed funds and some funds from casinos.
But I don't trust any exchange.
In Brazil, selling big amounts in p2p transfers may be a problem with tax authorities. It is not illegal, but it is more likely that they will demand more information, which is quite uncomfortable
