"you'll wonder why you haven't thought about it before."

People have, since day 1.

The issue then becomes, whos going to risk a dodore for 1g? What if you logout n game crashes, what if xyz reason

its not an accept solution and tbh a better way would be: Ask for a buddy key lol then you can just trade around freely without selling or risking anything. Just have to do the "delivery" part yourself.
