Likely to be true.
I've lived in what used to be called 'the Far East' and visited Hong Kong and some of the other places, including what was once called 'IndoChina'. At the risk of painting a very large portion of our planetary populace with an overly large brush, most of the Asians I have had contact with love to gamble.
BTC is a fun way for them to gamble.
