Neither China or Russia have any interest in an imminent dollar collapse as the ramifications on themselves would be negative and massive. IMHO that is why both of them have taken steps to slow Bitcoins growth to "buy time" to move their dollar treasury exposure.
Bullshit pro-American rhetoric, China and Russia have their own independent economies capable of production and trade, the American economy is an economy that is based off phony debt and the bond market, they rely on China and Russia to trade them worthwhile goods for their paper on the assumption that it's backed by something like gold and has value behind it. This 'everybody relies on America' crap is usually parroted by people who have done absolutely no research into how the debt and bond market actually works. China and Russia would only suffer a short term crash and would probably rebuild quite quickly whereas because America has absolutely fuck all anymore they're going to have to spend decades building up their economy again or going through another depression.
This is almost like somebody who is unemployed moving into somebodies house, they don't do anything and the people in the house pay their bills and do all the work, the argument perpetrated by Americans is that you're creating work for those people in the house by the twat living there, but this just isn't necessary and they're being forced to work longer because of this moocher. They'd be better off if they kicked him out and made him go and do something with his life and then they can have time for themselves and relax for a bit.
