There doesn't seem to be any intrinsic gain by using XRP over bitcoin in fact if memory serves me correctly when you fund an XRP wallet you have to burn 10 or 20 of them so you've got to spend five or ten dollars getting your wallet funded.
Is there really a hook for XRP?
It's a reserve, not a burn. Imagine just with that you stop any spam to the network, super speed transactions and paying less than a cent for each tx. Instead of paying 10 bucks each time you need to move your funds like other networks.
