First of all, no, earning nfts isn't anything cool. 2nd, it's not unique, literally any NFT game advertises that they have a player-driven economy but they fail to provide failsafe for instances where the game economy could potentially slide down one-sidedly that it'd have no worth or value anymore.
Honestly think it's just another sht game that couldn't be released in the competitive market so they released it as an nft to have some chance lol.
That is %100 true, there isn't anything cool about losing money, and I honestly believe that the best thing we can do at the moment is just staying away from them, trying your best with this NFT and game BS projects will always end with you losing your money, there isn't really anything that you can benefit from that.
I believe that the best way to go with this would be just focusing on how you could profit with it as much as you can, which won't be easy but I think it is going to be quite easy to handle, that's what I hope will happen. I think it is quite obvious that things won't change all that much if you just stay away from them as well, not like there isn't any other opportunities somewhere else, just focus on those stuff when you want to make some more money and stay away from these.
