Bitcoin casinos have been know stranger to the Bitcoin community. Especially dice sites which provide a kick for many gamblers. Dice sites are a unique way of gambling as they have not yet seen much success in the real world but are operating on large profits on the digital world.
As of lately many new dice sites have opened up accepting Bitcoin and other cryptocoins. While some of these casinos are bona fide many are bogus and fraudulent, rigging rolls to steal users Bitcoins and cryptocoins. Recently DiceBitco.in was found to be fraudulent as it was seen skipping nonces or results to make the outcome in favor of the house. This ultimately caused many customers to loose vast amounts of Bitcoin.
