Bitcoin will be accepted in more and more countries. Those countries that not have accepted bitcoin yet, will follow soon. They cannot afford to stay behind. However, governments will accept cryptocurrencies, but not without regulations and taxing. And that's a very high price to pay. Chances are, that with my and tax, bitcoin is no longer decentralized.
Thats right, that's sure to happen, I'm sure many countries will definitely follow what other countries have done by legalizing bitcoin, they will realize that, they can take advantage of bitcoin for the benefit of the country, so sooner or later the country will definitely legalize it
