Frankly, I don't know what TEXs are or how they work?

So far I have used both CEXs and DEXs, although I wish we could get rid of the need for CEXs but so far there is no good alternative.
DEXs until now are not a good alternative to centralized exchanges, for many reasons including the lack of sufficient liquidity as well as the lack of a large number of coins being listed.

I trade on the central exchanges and when I finish trading I transfer the profits to my wallet, so I only risk what I can lose.
