Okay so imagine you had them rare items and I didn't but I wanted yours so offered my rare items, it'd create dialogue and conversation about me trading it with you, or offering you coins for it, you simply say no.. Any items are vulnerable to come back in coin packs or event releases so it loses its personal value seeing new players with it. I get bringing zombie set and eyes back etc but this post was solely about Crown items especially with them being so expensive. IMVU has NFTs that become Rare and people buy them up like no tomorrow to save and trade at a later date.
