When we created the game, we thought first of all not about monetary interest, but about how to provide the game for free to a wide range of people. If, of course, people are interested in the game, then it will be possible to make a game for cryptocurrency.
Games on telegram aren't popular here, so it is difficult for you to market it here even if it is free. because at the beginning of its appearance, Telegram was already considered a scam field for crypto users. If I were you I will try to build the website like others, this is one way to build trust here. Even if your intentions are good, and have the output to create a real cryptocurrency game, but one thing you should know is, the people will play your game if it really makes them happy, not the fear to be loss.
Games are simply different with gambling games. OP posted it in a specified industry, therefore, it won't be surprising that not all people would be interested into it. If it is just the gme itself, then no doubt that's entertaining but the reason why most of the gamblers are gambling is simply because of money. Yes, bonuses are a good thing but a typical gambler will be needing more than that. This is not to generalize but as we all know, things do run in such reasoning. What I am looking forward is for gambling platforms to adopt such kind of games which is a more tricky. Problem is leaks with the winning outcome or nswer given that the result is centralized to the provider itself unlike with other gambling games.
