I am a Bitcoiner. However, I doubt that China or Russia will accept a hyperbitcoinization of the world. Some will say they have no choice. That may be so.
But don't count on them to support the hyperbitcoinization of the world.
China and Russia will not allow a fair monetary system over which they have no control to develop within their borders and then foster its growth. No manipulation and no censorship with Bitcoin. That's not what Xi Jinping and the CCP like.
China in particular has been advancing its digital yuan for several years, which will serve to better monitor and control its population. It is the last missing piece in the puzzle of the mass surveillance society that the CCP has been installing for years in China.
It is rather the yuan as a reserve currency that China will push in the future to Russia, the BRICS, and the countries of the South. And also the digital yuan.
For these countries, the interest of letting a currency totally manipulated by the CCP take over the American dollar is not obvious at first sight, but the resentment towards America is such that the yuan will gain in power in the years to come, it is a certainty.
For Bitcoin, the rise in power will continue throughout the decade, but it will come from individuals and "small" countries willing to change their future like El Salvador, not from nations as powerful as the BRICS can already be.
