China will relax their ruling & unban bitcoin imo. They will just impose higher taxes on those companies for dealing with bitcoin. I can't see how a government will want to miss out on more money by tax.
That's still pure speculation from you. The exchanges above are gets burdened by the regulation and by that they were closing down their service until no specific date.
I pretty agree that china will not going to miss tons of money by taxing bitcoin users, but they juts make too strict rules that affecting the whole bitcoin ecosystem there.
