There are ExpertOption, IqOption, OlympTrade and so one to trade with crypto currencies, and not only them. I think IqOption is the widest one, it is not only for trading, but for holding also.
I agree with your suggestion about IqOption. I have used it quite often due to its stylish user interface and lag free experience and it has helped me earn healthy profits for quite sometime. My second suggestion would be Blockfolio which lists all your holdings in an easy to understand manner. It reminds me of Coinmarketcap. I have been using these two apps for quite sometime and they have helped a lot which is why I highly recommend them. When it comes to mobile wallets, I recommend Zebpay which is easily one of the best and easy to use android wallets out there.
