Thank you for asking. Let me tell you the truth. NFT gamings, all of them, are Ponzi scheme.
If you look at NFT game as a game, sure, some games are good and have entertainment value, such as Axie Infinity.
But if you look at NFT games as source of income, then they are all Ponzi ?
Think, where the money comes from? Who will pay for the token, the "pet" you breed, the item you get from lootbox ? New user, i.e: new Investors.
That's it. Use money from new investors to pay old investors.
If you are unlucky enough to hold the bag. I.e: player who have not sell their NFT before the game close. You lost your initial investment.
Cool, how can I join?
