Robinhood is launching Bitcoin/Ethereum trading with no fees next month. I'm moving some of my GDAX volume there to spread around the third party risk, and also because of GDAX's performance/downtime issues. Robinhood is my go-to for for stocks/fund trading, so it's awesome to see them entering the space. Great interface and good management. It's rumored that they'll be adding more coins as well.
Binance and Bittrex are your best bets as a USA resident. I also love Cryptopia, but not for liquid trading pairs.

Rather, it's good for buying cheap micro cap coins and speculating on them being added to larger exchanges. Sometimes, the payoff is huge.
Awesome advice thank you ! I looked at Robinhood; "Were planning to operate this business on a break-even basis and we dont plan to profit from it for the foreseeable future says Robinhood co-founder Vlad Tenev. The value of Robinhood Crypto is in growing our customer base and better serving our existing customers. ~ Looks great to me !
And your Cryptopia advice opened up a new avenue I hadn't thought about

Bittrex apparently does not need me and I'm fine with that

So I still need another ALT site...looking.....still looking.....
