am new to forum, I currently use mainstream sites like betfair but as looking to gamble my bitcoins but wondered if dice sites etc need a licensee, and should I steer clear of ones that don't?
no it is not correct to giving license for gambling sites. because then all the people try to do gambling. gambling is not easy issue it is risky process. who want to become rich in easy way and they had no ethical values for doing like that business. so like that people interested to gambling. any government not encourage like this activities it is harmful to society so no one can give licenses for this.
nope I think you're wrong, in some countries gambling in legalized and when you want to build a gambling house you have to ask for permission and license from the government, in some countries like the USA (in some states), hongkong, china, etc legalize gambling and certainly have to go through a permit from the government to create gambling houses, as well as gambling sites, although it is not mandatory I think licenses will make them more trustworthy, and of course freely circulated in the country,
