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.
since Crypto is the new trend... so there are no second thoughts required to be given to the fact that it has grabbed all the attention it deserves lately. governments of almost all the nations are thinking of legalization of he Crypto market but what fears them is not exactly the difficulty involved in regulation of Bitcoin and other cryptos but the illegal usage and transaction that people may get indulge into.
I don't think it'd be because they fear the difficulties. Governments no doubt would need to get certain new policy frameworks but that'd certainly be worth it.
