NFT is the bubble. People are trying to sell "art" with real value less than 1 usd for incredible money
Why has it no value? It's comparable to a painting and a copy of a painting or more so a collection of prints number 1 - 20 theyre the same print but numbered and the value is in the number just as the value is in the crypto signature.
It's an odd concept becasue its not tangible but neither is and Cryptocurrency so by that logic crypto would be primed to suffer the same fate?
