Yeah this thing also comes to my mind every time I see an NFT projects made by some random companies, which there is no real value offered by them. I have seen some portrait images in OpenSea, and I wondered if there is some stranger to buy and keep that worthless portraits, because you can just find better images in Google, do photoshop on it, even printed it out with less price, if you just want to have the image. There is any crypto related value on it indeed, but neither of that NFT.
The real purpose of holding one of nfts is that some of the projects have benefits for a lond period of time which you can get free assets by just holding of nft. Because if a lot of minters doesn't flip their nfts it won't flop especially if the projects has a good roadmap and many people fomo in this project. For example holding an etherium nft with a famous background and community since they have an impact to the project, it will increase the value since a lot of people buy their nfts bigger than the mint price. As I say that holding them will benefit you and some of them in years will increase the market price.
I'm aware of the real purpose of NFT, and actually I own few NFTs in Rollbit. I get so many benefits like profit sharing and monthly free bet tickets by owning them there. The only thing that concerns me is some NFTs made by some random companies/artists that doesn't offer any value on it. They think NFT is a normal gallery to sell their paintings or artworks with expensive price tag. You can check
this an example, what's the point someone purchases this photo.
