You can check directly of their telegram but yes I do need some clarification about this game and about the prize too.
OP I just tried the site and it is just some prediction game which is on their coin whether it is going to raise or not. And I think this will be easy to manipulate because there is many players or even you hold the most coin so it is pretty easy for you to manipulate those numbers
The price was stated above on the OP. The main question here is how to participate. There is no clear instruction on both CBX channel for tournament and official telegram account. The only thing we can see is the people who already playing.
You should participate as usual, the problem ia about the payment as well, if this is for real there should be players that already claiming this becauase last time I take part on it and I lose this. And there is still on going players which is around 4-5persons. There must be a winner on that but yet I have not seen once comment that they are winning
