Poloniex is stopped again, at this moment Waves platform will get a lot of advantage from this if it could launch the new UI soon 
Those Polo guys intentionally didn't listed Waves on their exchange thinking this could make them troubles and now Waves has its own exchange with good token value without polo but Poloniex is facing instability issue for few days now. Waves is keep increasing to let us all ride more freely.
I want few things more than to move all my trading to the WAVES DEX! I am so sick and tired of Polo's crap
I hope the DEX will mature soon - it does look great already though!
A question: Will coins that are NOT on the WAVES blockchain be tradeable on the WAVES DEX at some stage? I am think XRP, XEM, STR ETC, ETH etc? Or will the WAVES DEX always just be trading WAVES based coins?
you will be able to trade those you mentioned, and more...all in due time, but other good things have been happening recently
