I can say that the main thing is not how much you can earn, but the game process itself. If you are thinking of doing this in order to make money, then most likely nothing will work. But you can play it just for fun, and maybe someday you will be lucky to win a lot of money. But you shouldn't hope for this and set yourself such a goal.
About the question about the use of crypto: yes, you can use crypto, but before you do something, you need to make sure that it is a secure platform.
