I am now using MEXC exchange which does not require KYC maybe OP can try it?
With Ratimov's review it is clear to me.
Yes why not use DEX has many USDT-trc20 networks available even it is simpler than CEX, I hope you can take good advice because maybe you will exchange more USDT as you mentioned.
Most non KYC CEX have daily withdrawal limits. MEXC is definitely a good exchange but they have a withdrawal limit of 5BTC per day. Unfortunately, is not available for US citizens unless the OP can use VPN.
