:)Do you want to make a no license without any security project of gambling?
I don't think it's a good idea
as far as my knowledge most of the gambling sites do not have the license...
That's wrong.All the famous gambling sites who genuinely operate as a legit business do have a gambling license if it's required at all by the country they're operating from.Otherwise,if it's against your jurisdiction,you wouldn't be allowed to play there.Like Ip blacklisting or showing a warning message.
True, gambling casino sites holds a high amount of money and there are lots of gamblers that needs security for their money. I think those gambling sites which are only starting don't have the license yet. But as they grow, they MUST have a license since they are operating such amount of money. Well established gambling casino site like Crypto-games.net, Primedice, Bitsler and other pioneer in terms of gambling site does have license.
Here in the Philippines, online casino's are being shut down by the Government because they cannot collect proper taxes to it. Hence, they are required to have a license first before they can operate such gambling site.
