I do not see that happening anytime soon, I do not think Bittrex sells any Waves Tokens. I could be wrong
They do -- see Mobile Go, Incent, and other stuff. So they do list Wave tokens.
Biggest issue is until Wagerr develop their own blockchain they won't pursuit/get listed.
MobileGo is not listed on Bittrex and it is not a waves Token, it is an erc23 token.
Incent is an erc20 token on the eth Blockchain as well.
Neither of those 2 are in the same situation as Wagerr, Wagerr is not an ethereum token.

Waves lists other tokens but not the other way around, next time you want to correct someone make sure you know what the hell you are talking about
