hoping to get poloniex or bittrex for TIME

I do not understand why in every ICO thread everyone demand Bittrex and Poloniex.There are better exchanges there volume wise and Choronobank has already announced livecoin and other exchanges.
Cause bittrex is where everyone went after mintpal was shutdown. I think thats a psychological thing.
And no, there isn't a better exchange than polo in terms of alt coin volume.
