I know a website that has multiplayer games and it shows the result of each game in mD5 hash mode before playing .
so It is the only trustworthy website to make money.
take a look and share your idea :
www.headortailbet.comSo it does list the hash format, but it doesn't give any guide as to how one could confirm the legitimacy of their bets.
As it's a new & relatively unknown site, I'd prefer to put my money on a site that's not 100% provably fair than on this site.
Besides, its design isn't really good and it's very boring to gamble at. I'd not even trust this site with my funds.
They don't show their fees either.
