I don't quite understand why you are surprised by BK8 ads on YouTube and Google? 
This is a fairly well-known and large casino in the region of Southeast Asia.  Now the casino is expanding its activities to other regions, which clearly speaks of their success in business.  Thanks to such advertising, including in BTT and this topic, BK8 will be recognized all over the world. 

And I wish devs casino further success in the development of other regions of the world.  Moreover, bitcoin and in general any cryptocurrency is a global universal monetary unit.
