More precisely, those who are currently still joining the mixer signature campaign do not use the exchange wallet, usually they will experience deposit restriction problems which result in frozen assets.
Mixers are still too sensitive to deposits from mixers, maybe if it is from your own wallet it will not be detected if you send it to the exchange, but don't be too reckless, usually the exchange detects it comes from the mixer wallet.
My own casino has no problems, because some exchanges still accept it until now.
There are no longer mixer signature campaigns on this forum? Or are you referring to external forums?
Personally I always move anything I buy or earn into a wallet where I retain the private keys It provides me peace of mind. Bitcoin is strong but with that power comes responsibility and a key part of that is privacy and knowing the present regulatory landscape
What about in a situation where you need to sell and convert what you have earned or sell profit from what you bought? How will you handle that? Will you make use of some DEX to trade and convert in order to be free from regulators, or will you still fall into using a centralised exchange? Some people actually do make use of self-custodial services, but when they want to convert their holding into another asset, they no longer care about the safety of their privacy.
Using a DEX does not necessarily free you from regulators. Decentralized exchanges like
Bisq can help to make trades more privately though if you weren't using a self-custodial exchange to begin with, started on a centralized exchange or trading using Bisq or another decentralized/peer to peer platform though are selling to a bank account, privacy is likely to have been lost at some point in the process anyway.
