So many Chinese people are engaged in gambling look at casinos in Macau and Hongkong they are being run by Chinese and every country that has a casino on it expect a Chinese casino operator, in fact in they operate online Gambling and casino in some countries like the Philippines.
The Chinese people might be the one behind the creation of some gambling company which are in Macau and they might also run an operate an online gambling site but I'm sure it wont be on their country soil because the government arrested 540 people last year and we both know that they know how to force people to their law.
Yes they are and it was confirmed several times, some local police have raided Chinese run gambling casinos operating targetting Chinese clients and they operate outside of China, one example is the series of raids in Clark in THE Philippines.
I've seen this news as well about Chinese nationals is being arrested due to illegal online gambling operation which do most likely target out Chinese clients.
Bitcoin is legal in China no doubt in it, China is founder of Bitcoin.
What are you talking about man?
