You can also try  Forkdelta and Yobit.  WTT tokens have started trading there a couple of months ago.   Forkdelta is similar to Etherdelta - they are competitors, and Forkdelta is the similar type of exchange - you need to connect MEW to it.

Yobit is a usual exchange, but about a month ago, as i remember, volume was very low,    but maybe situation has changed now.
