They do not have a gambling license, Sites who do not have a gambling license = do not play there.
Easy as that. Looks an easy scam. Serious betting sites will always have a gambling license.
I'm not defending this gambling site but Betfury started with no license and it took months before they have one, but they have a good reputation, and this is one of the popular gambling sites in the industry, there are other gambling sitess that started without a license, so let's give them a benefit of a doubt.
