I have a question for you. How to make governments accept bitcoin and not see it as a threat? So that one could use bitcoin in daily use, such as paying taxes or grocery shopping. What is there, other than anonymity, thats making governments fear bitcoin and cryptocurrencies?
Maybe be there will be a possibility that the government will accept bitcoin as legal currency because the country japan accept bitcoin as a legal currency so maybe there's a big chance that it could be accepted.
Only for japan's government, of course, there's no point for other countries to follow what japan have done. Though japan (only) accepts bitcoin as their legal tender but it's already made a big impact towards the demands of bitcoin, it's a good thing of course.
The anonymity of bitcoin itself actually not an obvious anonymous, everything can be traced once the owner of an address revealed, thus, it's actually not a threat to the government, just if they know it ofc. maybe government just consider bitcoin as a threat because it has the potential of taking over their economy and replace the current monetary system, but, who knows?.
Accepting bitcoins as a legal currency by governments is not a easy task. It depends upon lot of factors and the most important is the economic situation of the country. Japan and slowly India also moving towards bitcoin legalization will greatly help bitcoin to spread with more positive note and other small countries will adopt automatically seeing the big ones already in bitcoins.
