Ok NFTs are nice and fun and we have seen a growth during the last months/years.
but the market has no limit, and prices are out of any logic!
I am not sure if all of these items sold for thousands and thousands of USD will have the same high value after 5-10 years.
Take as example CryptoKitties, most of them have literally no value despite were sold or created for "real" money.
Most of users have tons of kitties that have no interest or value....
I honestly believe that you need to have a reason to buy NFT and that is what Kitties were missing. They tried something like kitty fight or something later on if I am not wrong, they tried some reasons, but just the "collectible" idea is not good enough, it will eventually always die down and not worth anything at all.
At the end of the day, we are talking about something that is quite expensive, today if you want to swap a token that you never swapped before with the accept thingy and the swap itself the gas fee could cost as much as 15 dollars, of course each time after that is 1-2 dollars but still, to get in you need to spend so much money. I personally do not see myself spending that much to start on just "collectible" stuff. However, these days gaming became a lot bigger and I feel like maybe we could actually see that part of the NFT world grow quite big.
But why did Pokémon work? I have no idea about Pokémon and what you can do with it, but it did work as a collectible. Or these figures from those chocolate eggs work as well as collectibles. Anyway, NFTs can also be applied to art and songs. What if you buy the NFT from an unknown singer that you think will one day go through the roof? I think it could lead to talent search, NFT markets would be the platform for people to browse through trying to find the next superstar buying a piece of his song or painting.
