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.
