So a digital certificate of authenticity.You got to be kidding me.
NFTs have 0 utility, why are you comparing them to other things
it’s just a a unique code that you purchased that says you have something unique.
the idea that the code will later appreciate in value is a fukking scam
All the news stories that NFTs have been bought for a certain dollar amount are straight up “pump and dump” schemes
Going by your concern then getting a trading card or comic book officially graded is a scam as well.
