Hello!
My proposal is to exchange all fees gathered through the pools in xmex and deliver them to the stakers, liquidity providers. This way, we have a buying pressure and we speed the process of the xmex early unlocks from users when they are satisfied with what they get, making a positive feedback loop.
Thanks.
Thank you for the suggestion @l30gd4n and welcome on the xExchange Agora! 
The incentivizing mechanics are in a delicate equilibrium and were well considered before being implemented, to make sure they provide interesting benefits for all xExchange users.
If we would change swap fees rewards exclusively to xMEX (so locked for 4 years), we would diminish the current incentives for liquidity providers, which may hurt the xExchange growth on the long run.
