You are sending me to a section where most of the "projects" are scams and nobody trusts that section anymore?
No thank you
If the mod is yet fine with me being here, I will stick here.
The mod agreed with me.
I can think of several options how this scam works:
1. He does nothing, but still has 50% chance that user wins and will pay him.
2. He is in contact with casino websites,some sort of referral program and gets bonus on money his clients lose.
Or, much more likely, he's pulling a long con, like alia: paying out 0.01
BTC, and then instantly asking for 1.2 Bitcoin. If someone sends that, the scammer disappears.
Furthermore,casinos may even be aware of his scam, and let user to win first time(if the amount of money is small) and then when stakes will be higher casino will win.
That's what almost anybody who pulls this scam claims. It would mean the casino is cheating, and if that happens, you could PROVE it using the provably fair system. And since those casinos are in business for years without any evidence on cheating, it's safe to assume they're legit.
