Why would people use a wallet if there's a chance it could take and hold your coins, for who knows how long? Makes no sense to me as it defeats the purpose of having a wallet. It really doesn't matter if they are doing what they do for KYC/AML compliance or whatever, it doesn't make sense to keep coins there if that's all you are doing. I get maybe its a matter of convenience for some, but people should learn a bit more about how to self-custody rather than risk interrupting your wealth.
