there are people DO get rich playing games as a profession,
i remember in the documentary in astro "I,game"
there are atleast 3 people in the game "second life" earn milions
some just take aventage of the currency exchange rate.
just its is an extremem rare case, like 1:1,000,000

others just treat it like a party time job, able to earn something small like a hand bag or suff.
maybe like the infamous real money trade,

i think there is a flaw in china rule,
you can't sell gold in china, but there is nothing stated agains selling it to foreigner
