All these are just predictions about what could happen in the future about bitcoin mining, it will be good if it gets to governments of individual countries to start engaging in bitcoin mining, but this may not happen, or possibly it may happen. But, it will be good if it happens which is an indication that the market price and marketcap of Bitcoin would have significantly increased while the world will support more of bitcoin.
Some people said bitcoin is controlled by China, but this is not the fact and not true, although, China mine 65% of bitcoin, while most of the Bitcoin are sold to outside of China, which means they are not controlling it. But the data which I saw on the link provided below truly suggest good information, that in 2017, China mine 75.62% of bitcoin, while this has drastically be decreasing and now it has decreased to China mining 65% which may likely decrease further as time goes as more countries are now supporting bitcoin mining.

With the article, it is clear that some countries are now supporting bitcoin mining, these will be the country that will not take Bitcoin mining for a joke but as a business opportunity to their citizens which can increase their gross domestic product, this will help in shift China aways from mining the most new Bitcoin into total circulation.
Bitcoin is just at its early stage yet, if the world support it, it will be more than an asset because it will be the greatest of all which its value will continue to be increasing further. It is just a deflationary currency that is worth going mainstream and becoming the first world currency and the most recognised asset in the future.
