Waves Dex is no serious alternative, Dev can't be serious about that! I still hope they get listed on Liqui soon. Or this coin will die faster then you might think.
Very disappointing to get no info about delisting reason from dev. He was very unsympathetic from the beginning I must say.
Don't be too quick to disregard the DEX. It's not uncommon to see millions in volume over a short period of time. Other exchanges will come in time.
