I think that all crypto betting games are designed to make a profit for the site owner, and therefore the odds are always against you. I would avoid them, and try some other form of gambling where you have a better chance of winning if you use your skill and knowledge.
From what you have said above it seems you a little bit contradict yourself if am not mistaking. All the gambling company are out to make profit and known of them are out to make lost though list is inevitable in business but should not be that much.
