Matchpool going to get listed in Bittrexx anytime in few days. Time to buy and hodl. 
matchpool have already proved its value and potential with a very sucessful and record making ICO fundraising. and I think exchange really doesn't matter. if it get listed to liqui.io it is also a good thing. bittrex is not important.
It is better to get listed in higher volume exchange. And the more exchange, the more liquidity, the better.
