So I week ago I used a mixer to send .1 eth from one wallet to another. The wallets I used have never been sent to or from a CEX but did have the connection indirectly. So yeah I just got banned from my main exchange that I hardly use anyways but would need it to go fiat on/offramp. So is anything connected to this wallet tainted now? Will I be able to use a different CEX for on/off ramp? I am american btw. What do I do now?
And why do you think the exchange banned you from using their service even though you didn't deposit the mixed crypto to the exchange?
Usually, the exchanges won't ban the account unless the deposited fund is tainted not because the person may deposit the tainted funds and they have no right to assume in that way.
First, ask customer support about the reason for your ban. And if you already did, just ask for the actual reason irrespective whether you get back your account or not.
