I think previous issues raised by china its their strategy to hold more bitcoin in cheap price . then after Russia also came up with same issues but its couldn't able to succeeded. If china would done without any proper intention then they should be regretting now.
Even i am also thinking same chinese are proper strategist they could have knowing the price increase and also bitcoin fork so they prepared to get cheap coins by doing such all issues. Now price climbs back they will release their holdings.
