The most promising case scenario is gaming:

Games are becoming more and more interconnected. Imagine if you will a simple game like Magic. It used cards, etc. People would pay a great deal of money to get extremely rare decks, etc. The limiting factor was the company printing the given card and how many they would print in relation to average cards. This whole ecosystem can be moved to a digital one. The total supply of these cards in the world can be seen along with the ultra ultra rare 1-of-a-kind cards. There are guaranteed to be only 1 copy of the given card (via NFT technology) and you are the actual owner of it and the only one who can play it.

In things like World of Warcraft or a million other games. Hypothetically a company could "Mint" the official "Marvel Thor" armor set of which there are only 100 in existence and people would buy and exchange these. They actually can get added to a "crypto wallet"/"NFT wallet" and you possess the item outside the context of the game, but may only be useful in the game.

You can also imagine vintage star wars action figures.... but perhaps this is a 3D Metaverse Oculus art gallery piece of the millennial falcon.

Will I ever buy these types of NFTs? Probably not.

NFT is Non Fungible Token. It means that is completely unique and can't be cloned/assumed ownership of someone. It is tied together with that token and when the token transfers, the ownership transfers.

I see NFT and blockchain eventually getting rid of things like Title Insurance and even deeds and other such legal documents. There would be no need to have title insurance because "everything" is on the chain. It is 100% clean. Takes 2 seconds to take a look at it, and if it's not there it's not legally binding.
