When the people know that there is money on it, they will do everything just to jump into it and make money thus creating this hype.
When ICO has been the hype, many developers and people earned money from it and many projects too turned into a scam.

Same thing will happen to NFT's. TBH, I just don't understand why in the hell these investors are buying a pixelated JPEG art hoping that they will earn money from it. I mean I'm not good at art but I don't see the real value into most of the NFT arts out there. With regards to NFT gaming, most of them will become rug pulls or a dead game. Though some will become successful, a huge number of NFT games will be dead especially when the bear market comes.
