If it's testnets, obviously I don't want to try it and I've also seen that the payout is very small and it depends on the points and quests we complete and it would be a waste of time. Now the airdrop, the problem is that many people participate, it is drawn randomly and the chances are very small. It also depends on the project, so do your research first. NFTs difficult because not as profitable as they used to be, because yes, since the AI boom, everything is easy if you generate 3D or some kind of fantasy virtual asset image. However, the NFT space still has a lot of potential, but for now it is more important for me to be careful and not over-invest.
Any campaign that has points/quests, it's waste of time and this includes all this platforms like zealy/questn/galx. The harder the task the more the reward, like running node — not many people do such tasks, also the less saturated the project more the reward.
Most nfts are useless, only aptos rewarded for holding nft, I don't think it's to do with AI tho.
