Trading system

I don't know if posting this in Concepts & Creations is a good idea but i'll do it anyway. What would be nice is a skin trading system where you could trade skins that you own to other players. Also, the trade wouldn't need to be of equal value (ex: a 975 skin for a 975 skin). This way, people who want a certain skin could exchange it for a skin they don't use whatever the rarity of the skin. It's just an idea and it probably won't work. Also, if not possible, maybe the trading system could be used with skin shards. That might make things easier
