Was just using a coinbase account cause I think transfers sent can only be traced back to coinbase which is quite generic but they closed my account cause of my location. Don't want to deal with an exchange if possible.
If you're doing something that will get you into trouble with law enforcement, then they will easily make coinbase or almost any other centralized service give up the full list of your customers. But if this isn't a problem for you, you can use some other centralized service as a "wallet" like an exchange or a casino. From the outside it would look like all your customers are receiving money from that service. But the withdrawal fees are generally pretty high regardless of the actual network fees. And exchanges could probably close your account for such activity, because they will see that the account clearly isn't used for trading.
A better solution is to use coin control to have no more than 1 output (aside from change) and immediately mix your change outputs and never used unmixed inputs.
Yes, I only care how it looks from the outside to people who don't have Coinbase records. Law enforcement could get the data but I don't care about them.
Coinbase has a wallet so I think it is ok to be used in that way. But the other exchanges I looked at (e.g. kukoin, stormgain) only have a withdrawal option so I think their website is not meant to be used as a wallet and you are right that the fees are prohibitive.
What is the best wallet to manage coin control? Any that can be managed by different users?
