The very best wallet out there. If you don't own your keys you don't own your coins. Allows you to have multiple crypto currencies. You can easily exchange currencies into other currencies using their integrated Shapeshift.io integration, which basically makes the system an anonymous exchange. Also their system works on the browser and all other platforms, passphrase gets you access on every device, pc, mac, mobile, whatever. Lastly they use an HD wallet system that creates a new address after each use, that way people cant go snooping back into your account and see how much you have left. Their team is also top notch, they have been at early on.
For an exchange to trade into fiat currencies, I would recommend Kraken.
