I don't rule out the possibility that someday there will be platforms that offer various games for stakes using crypto currensy. As I said before, the community of chess players is quite small, so many different games can be hosted on such platforms, and not just one. Chess, checkers, backgammon and the like. This will allow fans of games with small communities to be united in one place. It seems to me that this niche is not yet occupied. It is possible to add tournaments to the addition to betting games. And all bets, winnings in crypto on all familiar games.
The easiest way to gather all the players in one place from a game/sport that is composed of only small community is to host a huge tournament. I mean a tournament with a huge prize pool.
Chess is one of the most challenging board game in history, I guess there would be a lot of people who knew how to play chess but most of them may not be interested in playing online due to several games offered in the online world, but adding crypto as the prizes for the tournament might catch more player's attention.
