From the analysis  start by the third part.

The most popular  btc gambling game is in China.  and the  website is www.btcfanbei.com

The domain name is created from Chinese pinyin  which means  double what you bet.  (fanbei)means double in Chinese.

The site shows the result from 1-199  randomly and hourly.

1-99 for small
100  for  special
101-199 big

And if you bet small or big and you get the same result ,you double what you bet.

And if you bet special and the result is 100, and you get 100 times what you bet.

As far as we can see. every  hour there are about  800 btcs . and 24 hours a day.

So btcfanbei will be a new style of gambling.
