They are just getting too much buzz. Though they are one of the largest countries by population and policies made by them would have immense effect in comparison to smaller countries, a lot of small countries in Europe and some in Asia like Hong Kong, Singapore, Taiwan and South Korea are much more friendly to crypto.
I agree with this,those 3 countries are the countries who made a recent big adaption on crypto that made a news and headline around the bitcoin world.There still alot of country who really supports bitcoin compared to russia philippines and india.
