not exactly sure if the concept is really provably fair or not , but in the first place why to use telegram instead of a site ??
everytime I see telegram involved with money I remember larawith me the famous ponzi site that used to telegram and then collapsed with millions of dollars
new ideas are good but don't like this one in specific
Agreed saw the same case on a few gambling games like Poker and BlackJack who run and disappear after gaining a lot of audience. This are the types of games where it is harder to track who the culprits are because it will go through Telegram first unlike having a gambling website where you can track it via domain and ip address. This game might be fun if you are looking to bet on your mobile phones but I wouldn't trust a big amount of money to their game as their are better alternatives out there running inside a site.
