So does this mean that shapeshift and changelly are exchanges built under the wallet of coinomi,exodus,mycelium. And mycelium is an android wallet for which the user has access to his private keys,but exchanges do not provide the private keys to the users,I'm confused here.
Any how,I created an account in changelly and they only have like 10-15 altcoins to trade with. So its big no for me. Shapeshift I have to check out then.
They are actually normal exchanges with an API that allow wallet providers such as Mycelium to integrate them easily and you're always in control of your private keys in Mycelium as the they will simply ask you to send the funds to an address.
