Might help make life better if bitcoin becomes legal currency. Many parties will benefit from bitcoin. But for a country less able to protect value of currency, it may be an inflationary disaster for the country and its people.
Bitcoin is representing a technology that can disrupt with how we do things most especially in the financial sector and so far blockchain technology is praised as a very innovative way. There are now many countries who recognized Bitcoin as form of a currency...some are doing it for taxation purpose and some are laying down regulatory requirements and platform inorder to make sure that Bitcoin is not being used for illegal purposes.
Adoption of Bitcoin for all countries can take time though even in countries where Bitcoin is still illegal to own I am sure that there are those who have Bitcoin secretly. In the coming years, I am sure we can see a big boom for Bitcoin most especially if the scaling problem can be solved once and for all.
