The last game I got to play to earn cryptocurrencies was Axie Infinity xD I enjoyed it a lot, apart from the income I received I liked playing it, but well you know everything that happened later, since then I decided not to get into any kind of cryptographic game.
About this game that you comment, I can say that it is quite entertaining obviating the money. Some time ago I got to play several games with the same theme, I remember that one was set in the anime "Naruto Shippuden". To advance if or if, the characters must have a good level, I don't know if in this one the sets prevail, but in the one I mentioned you also needed good sets to give stats to the characters.
It is good to know that there is a game of this modality that in turn can provide you with some economic income, although from what you say it seems that it is not much what is generated.
Thanks for sharing, it was good to read you and learn about this game.
