You should understand something, which is this, its quite different to see such happen when you get the news in form of rumors or from a media agency but when the president of a county comes out to declare support for something, that means its huge and this is not just any president but by that of a country that has been deeply rooted in cryptocurrency, i believe you've gotten your answer as to why such is possible
We waiting for America to come out of their shell and support BTC. Mahn it's not going to be an easy world after then. When crypto go 100% regulated and adopted by world bodies even your small BTC will do big gains.
Am sincerely sceptical about bitcoin being more gainful when it's been regulated. I believe that Bitcoin derives her uniqueness from being decentralized and several persons are holding bitcoin because of its decentralisation. Regulations may affect this purpose and lead the holders to invest in something else.
