I think this kind of game have a very small chance of winning. And I don't think that this is really secured because they don't need KYC so in short they are no concern whatever what happened on your investment. I hope they can improve their features specially in terms of security.
With 0.5% of house edge I believe you will have a higher chance to win instead of others dice site which is only 1% house edge. And btw chance to win is still depends on your luck so there is no way to get money easily especially on a gambling site. And btw KYC is needed to make sure this site is not a scammed site? Are you for real? Do you see many dice sites that without KYC has a good reputation out there? You really need to take your time to do some research
