They don't have any system to check bet but I think they are fair the same.
Don't worry it's really easy loss coins with dice, I have also lost more than 0.01 btc playing only here.
And daily I waste all money I can earn with faucet but they are free and I hope to get a good amount of ticket reward (and exchange for a good boost income)
That is the beauty of any gambling. If you gamble with the intention, make money so you will end up every day in frustration and you will lose your peace of mind because gambling is meant only for having fun during our free time. Hope you learned a lesson and will not repeat again.
