I think the ability to sell your items will be really nice, since sometimes you grind for a really expensive crate, but get the one item you don’t want. It can take days, even weeks to re earn those coins which is really annoying. With seeling the accessories and faces you get from crates, you can get most of that money back, if not all so you don’t have to spend that long again. It would be even nicer if you could sell stuff like clothes and hair in case if you don’t want them anymore and want a bit of extra coins.
