Deposit fees - how do they work?

Deposit fees are a bit different. After creating a collection and adding NFTs to it, you will pay a specific amount of deposit fees. Any collection/nft added to the Asset Hub is saved in the blockchain storage. This storage is replicated, and every change is tracked (by transactions). To prevent spam, parity proposed a returnable deposit.

Your deposited fees will be unlocked when you burn NFT/collection. Only the owner of the NFT can do that, so if someone buys your NFTs, you cannot burn them. Also, you cannot burn the collection if there are still NFTs in it.
