Can anyone tell me if you know any website where you can play online chess with other people
and that both man can invest crypto and winner takes it all?
I have not heard of any chess playing websites where you can bet crypto. But if you were to ask me, I would probably avoid it. Chess nowadays is a game that has been overhauled by AI and computers in general. If your opponent is using a computer to predict the best moves, even a chess champion of the world does not stand a chance. Going by that, it would be extremely easy to cheat your opponent out of his money. So why risk it?
In fact, unless a game has some sort of element of random chance (probability), then it can be easily taken over by an algorithm that lets you (or your opponent) win every time.
