Currency exchange shop

I'd like to suggest the addition of an in game currency exchange shop. In it we could take currencies from shops we really don't use and exchange them for more useful ones that we are needing or wanting. There would of course be a going exchange rate from one type to the next depending on it's in game value. Much like real world currency exchanging works. But this would provide all players a way to actually make use of their currencies they don't really use much. I believe it would be well received by every player across the board from F2P to P2W as all will be able to reap the benefits of having such a shop. Thank you and let me know what y'all think of this idea?😊🙏🏻
