About Jaxx, you are right. However, what I found interesting about it is the fact that it contains 2 anonymous exchanges inside it, allowing you to change a cryptocurrency for another one without offering personal information.
Those are probably some centralized exchanges that can freeze your coins at any time, and they usually charge high fees for exchanging coins.
AtomixDex I send you is also exchange but decentralized and they are using Atomic swaps, so you can swap Bitcoin with other coins and vice versa.
