Looks like the previous rumors have been confirmed. Binance just released an announcement stating that, in order to comply with regulatory requirements, several exchanges including HTX, EXMO, and ABCeX have been added to the list of platforms they will no longer process transactions for. They advise users to avoid directly or indirectly transferring or receiving assets to/from these exchanges via Binance. If you continue to attempt this, your account may be subject to review or freezing.
