I deposited some coins that are linked to eXch (I didn't even use it myself, it's like 2 people back) to an exchange and my account was frozen as a result.
Which exchange was this?
MEXC.
Deposited a small amount of BTC, account instantly frozen.
"Your account has been involved in high risk activities. In order to comply with applicable laws and our anti-money laundering obligations, your account will be restricted until further notice."
They won't let me withdraw my coins. Who knows what "until further notice" means, as far as I can tell, I got robbed.
The first step is to avoid using centralized exchanges (CEX) for crypto exchanges, as they will definitely record valuable user information. Even instant exchange services that support XMR usually keep logs.
