Do you think governments are afraid legalizing bitcoin because it's difficult regulating its use, circulation, determining individual's worth, earnings and may lead to tax evasion?
If the governments are afraid to Bitcoin maybe they are just protecting their citizens for the wrong usage of Bitcoin as a digital money, I think every government in the world must make a specific department like for example 'Department of Cryptocurrency' to study the benefits and negative impacts of Bitcoin and other cryptocurrency in future of their country because it is now a trend and more new people in different countries are in these Bitcoin scene.
Denmark is one of the most technologically advanced countries in the world, Denmark is also the most frequent campaigner and persuasion with the elimination of cash and in exchange for virtual money like bitcoin.
Although bitcoin is well received in this country, but the government does not give 100% of their support to legalize bitcoin
