Lock WRAP for higher rewards

Before WRAP launched my understanding was that the only way people can earn the fee % from all wrapped assets was by locking their WRAP for a certain amount of time, not just by staking it. I thought that was a great idea. IMO there needs to be some lock in place or at least a withdrawal fee(used to buy back and burn WRAP). You could even just add an option for WRAP locking and those who do get more Wtoken rewards %.
