You mean that i use TOR to open this exch.cx and convert my USDT to XMR and then again convert XMR to USDT (to a new address)?
Also, i check that EXCH.CX does not have USDT trc20 ?
The exchange dies nit have TRC20 USDT. I hope the exchange will support it, it is not that old and they will support more coins later. Only ERC20 USDT that the exchange is supporting. You can read what FinneysTrueVision posted, but you should know that coins can be seized on instant exchanges because they are also centralized.
