I strongly think that government should legalise bitcoin, because it may become a great revenue source for the goverment by imposing taxes of more than 30% and it can develop our country in so many ways.
This is what everyone one is imposing the governments to do. They do know the benefits and the growth in adapting bitcoin and other crypto currencies. The reason for not taking a step further is to sustain local fiat's value up in the market as this is what the primary element for a government. This is why the banks are against local currencies. This is the reason banks control government not to adapt crypto currencies.
although it is still the government must take action to control the use of bitcoin because it also can reduce unwanted actions such as theft or murder, because when the spread of bitcoin freed just not only the fantasy criminality will increase but it can be a reality, it would be nice government crack down on it so all usage of bitcoin can be controlled.
