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.
