It is hard to predict that any new coin will be the next doge, the reason is once a new type of cryptocurrency is introduced and it has seen success, it doesn't take long for that particular night to get saturated with new projects and the same already applies to the NFT space.
There are a lot of great NFT projects and there are also a lot of sub standard projects too, so every investor have to be really careful about the projects that they choose to invest in.
