they can't publish items in their custody (physically in their possesion) because that's a security risk for the buyer. all assets the own on plunda are in a central location. this has downsides too, but the upside is users can rest assure their assets are real and secure.

so yeah, if a user owns an asset on plunda.co they can resell / publish it for sale.

in the future a deposit feature will be added so that users can send their collection in to plunda HQ and have it digitalized and added to their plunda account.

(and of course a withdraw feature so they can have their assets sent to them and they can take physical custody - at which point the digital version of their asset is removed from their plunda account)
