So is any "art" that can be CTRL+C-d.
On the other hand, let's not underestimate the imbecility of humankind, so maybe you are into something.

I think one of the biggest problems was the lack of transparency with regards to sales over at Opensea. From some of the stories I glanced, there wasn't much organic trading, but more so between Opensea themselves, or between people who knew eachother. I think for there to be any hope for NFTs, there will need to be more legitimate price discovery.However, NFT's are very very very very very risky , sure, they may be very rewarding too, but only invest a very very very small amount and do not let it be a big portion of your crypto digital asset portfolio allocation
digital asset on a blockchain that is governed by the parameters of the smartcontract code that issued (or minted) the NFT

No they're governed by the normal legal system. Who do you think you're going to call, the nft police?
If you want to buy the rights to something do it in a way that leaves you with an actually enforceable contract. Show up to court with a signed, notarized document, not a sob story "I thought buying this crypto key entitled me to xyz, but I couldn't be bothered to spell it out in a normal legal contract, so now I get to waste money on lawyers."
The problem is that if you see an NFT go from 1 ETH to 100 over 5 different transactions, you assume that there is a market for these things. But when you later find out that all of these transactions were between people who knew each other just to bid the price up until someone outside the group buys, then this is a big problem. The last guy expects to also sell for higher, following the pattern, but he is the sucker because he will quickly find out that now, nobody wants to buy from him. I remember looking at these things before and sometimes after only a day, the last buyer would try and ask for essentially the price that he paid, and now he couldn't unload it. I think lots of people were trying to make a quick buck by flipping it quickly, but alas, many sold for a big loss.Not sure if I answered any concerns of all interested, but I'm just sharing info from first-hand experiences with NFT's and marketplaces and transactions

You're speaking from the pov of someone from the US
Yeah, I think the bloom is off theNFTs might become a useful shorthand at some point when accompanied by a real contract but just buying an NFT because "the value might go up" is like buying a blank sheet of paper because it might turn into a bearer bond or stock certificate.
