Bouncing an idea

So I recently saw that Crypto.com is bringing RVN on board. They were one of my first exchanges so that's pretty exciting for me. What I'm contemplating is this: Once they create a wallet that accepts RVN use that as my deposits for mining and then top off their card with RVN when I need it for whatever. It just feels like the most efficient way of being able to use the gains from mining. Let me know if you guys like it, hate it or have a better idea.
