Try Coinbase and GDAX. I don't do bad there. The money is ensured and after the recent Ether flash crash, they decided to honor trades and insure losses. If you create an account and buy or transfer $100 worth of crypto, we each get $10/BTC. It's legit. My buddy and I tested it the other day. Here is the link if your interested. I also up-voted this for ya. Better luck my friend! https://www.coinbase.com/join/592c79a24540cdd881e6f701
