Every developer interested in making (a lot) of Easy money by riding the crypto bubble. Maybe the question should be what gamer would be interested in paying for such a game (i.e. paying significant sums for pictures of cats and paying more at every turn...you can’t even give a picture of a cat away free without paying gas), but the answer is the same...any gamer wanting to make money off the cryptobubble.
Blockchain can be marketed with terms like immutable, decentralized, and smart contract all anyone wants. However the reality is it’s all a race to the bottom based on greed and speculation.
