NFT's that Contain other tokens

I think it would be useful for gaming and i’m sure in other ways as well.

For example, you could have a wizard character NFT that contains a magic staff NFT and a backpack NFT. The backpack NFT could contain various items that are all NFTs. The backpack NFT could be sent to another player’s character NFT or wallet and all the contained NFT would be sent as well. So it’s just like a folder hierarchy.

Another related idea is for the NFTs to actually hold ERG in them as well. You could set some or all of the royalties on a sale event to be sent back into the NFT itself. You could always burn the NFT to extract the contained ERG.

This would create an undeniable value to the NFT, take ERG out of circulation and may have some beneficial effects in regards to wash trading.
