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.
You're still new so I'll forgive you. Try to remember and revisit this thread in 3 months and then let me know how you feel about Bittrex and "Aero."
