Not all. I would like to think that a portion of the Chinese Bitcoiners are enlightened and know that they should stick it to their government in times that it is truly needed. Being a Bitcoiner could be one of those "sticking it to the government".
If it was possible, I believe foreign exchanges should start getting a good number of those Chinese traders. If Localbitcoin's numbers are up then that means there is a good market for foreign Bitcoin exchanges there.
I think they're all used to being shit on by their government, just like all murricans are used to bending over and letting the IRS rape them every April. No one is exempt.
I doubt any Chinese are trading bitcoin for philosophical reasons. Sure, they are trying to use bitcoin to hide money from the government but they aren't "sticking it to the govt". They're terrified of the government.
If you think about it, Bitcoin is the perfect medium for them to rattle the cage. The strict laws will subsidize BTC because of its disruptive nature. How is the volume of Localbitcoins over there. It must be rising by now.
