In my opinion, bitcoin has nothing to do with the emergence of inflation in any state. States do not legalize bitcoin for other reasons. The Chinese government, for example, last September said that the crypto currency is a danger to the economy of the country, since it allows uncontrolled withdrawal of money from the country, others say that bitcoin is too risky a form of investment and is beyond control and supervision. Also refer to its greater volatility. It is because of these reasons that the legalization of bitcoin and other decentralized crypto currency is very slow.

If that will be happened, it will be great that the countries itself will be able to deald and trasact with the bitcoins in future goals and success that it will reached in many years.

Bitcoin is hard to control so I think many countries are still not open to being legitimate. These countries have a centralized economy and they are used to control or monitor their currencies to control inflation and other monetary problems. It seems to be difficult to realize bitcoin to be legitimate in all countries because there are so many pros and cons to bitcoin. Each country has different thoughts and perspectives on bitcoin. We can not be that easy to force everything to have a common perspective.

This is quite difficult to say. Because many people do not believe in Bitcoin and the government does not want Bitcoin to penetrate too much into life

Bitcoin is hard to control so I think many countries are still not open for it to be legitimate. These countries have centralized economies and they are used to control or monitor their currency to rein inflation and other  monetary matters, yeah, bitcoin it's very hard control!

I think it will be hard for bitcoin to be legal in all countries. because the government still can't believe to bitcoin

Maybe some countries now have legalized Bitcoin for the eyes of the work or in the commodity trade. Because Bitcoin indirectly can make money for some people.

And also when a country has an Exchange, the tax from the Exchange can provide input to the government for the welfare of its people.

Bitcoin can not lead to inflation for the country that legalizes it. As an example we see Japan that has legalized bitcoin, does Japan currently experience inflation?
Clearly bitcoin can not get legitimated in all countries, because every country has its own policy against bitcoin.

I think bitcoin won't get legitimacy in all countries specially for the countries who's not open on this kind of cryptocurrency. Or maybe it will take a very long time like maybe 10-20 years for bitcoin to be legal on the whole world.
