None of them.
Exactly this. Stay away from Bittrex. They do not deserve your good BTC.
+1. Bittrex is a cryptocoin graveyard. Even worse, they will be more than happy to list a scam coin pretty much immediately in order to get in on the profits (remember Veilcoin anyone)?
If you support Bittrex the scam coins will just keep coming and coming (as the goal of all scamcoins is to get on Bittrex so they can be dumped for BTC). I am hopeful that people are smartening up and eventually Bittrex and scamcoins will just fade away.
I disagree, they may list shitcoins, but someone has to list the newest coins... I like Bittrex, i found Aerocoin there, and its an absolute diamond in the rough...some great devs for an alt, and ive sifted through some trash coins...take some time to look at aero, and youll see bittrex isnt all that bad.
