Just sell it.
Both of you will get luck.
You get TC the other get your unwanted item.
If you do some giveaways like what you said, the lucky person will be addicted in this and will end up on begging items.
You can also make an event to see who will win the item you are giving away.
If you keep on giving away things without getting any credits, the person who gets your item will be a "parasite".
Parasitism is bad, but if you do my suggestions above, mensualism will happen.
So both of you can get credits.
