Many normal Chinese people play with the stock market. I tell some that what they do is too risky but they do it anyway. It is basically gambling, but if they knew they could do the same thing with bitcoins....
like Bitlotto where 99% of the funds bet are returned as a jackpot prize to the winner, last one was > 100 coins
