Sell and exchange

During the game I had collected a lot of items but I don't know what to do with much of those. So I thought " why I can't sell those to someone else? Maybe someone is searching for this? " and if I droop a special weapon but not for my character?*
I think people should sell or exchange their items also just with their friends.*
What do you think?*

They are already implementing a system to *give* other people items.
It will be upgraded into a proper exchange (eg I give you money, you give me item) in a latter update.
