In Asia,
There are plenty of Brick and Mortar casinos that are operated out of Malaysia, Macao, Hong Kong, Thailand etc. Some of them have the online versions. And there are many "unlicense" online casinos too.
Those accepting bitcoins so far, I have not encountered in Asia yet, unless I missed out any newer establishment.
But for sure, bitcoins are steadily being used in many establishments in Asia, apart from the heavyweight users in Japan, Korea and Hong Kong. Online gambling outlets and betting sites are for sure, will trade more and more in bitcoins in the near future .
