you all know very well how NFT stemmed from blockchain for managing digital assets,
How would you define an asset? Do you think this post I made here is an asset? Can I sell it to you for a million dollars?! That's what NFTs are. Nonsense being sold to people for a lot of money. They can't be called assets, and they are not unique. Anybody can make countless number of the same exact thing.
based on description of NFT from Wikipedia [1] we have "A non-fungible token (NFT) is a unique digital identifier that is recorded on a blockchain, and is used to certify ownership and authenticity."
They are neither one of those things.
Imagine the "art NFTs". Right now I can create some digital picture, turn it into hundreds of NFTs and sell the exact same thing to hundreds of people. None of those NFTs would be unique nor would they certify those who bought them because that digital image is on the internet for anybody to acquire and even to create an NFT of their own and sell it to more people!
"An NFT is a digital asset that represents real-world objects like art, music, in-game items and videos.", therefore certifying and clarifying the ownership of something in real-world is the most capability of NFT.
Can I make an NFT of the Mona Lisa? Yes.
Can I make another NFT of the same Mona Lisa and sell it again? Yes.
How is that unique? And hos in the world does that clarify ownership of the Mona Lisa?!!!
so why we do not convert a specified amount of e.g. 3.698521 BTC into an NFT asset and store on the same blockchain,
For a very simple reason that interestingly enough has nothing to do with what I said so far:
Bitcoin is a payment system not a token platform.
To put simply, for the same reason why you don't eat your soup with a fork.
