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.
Because through legalization they think that bitcoin can manipulate them and have tax, they want to be legalized all profit for their people from cryptocurrencies into fiat in order to controlled and to have a taxed on it. Some countries now are starting controlling bitcoin to their place, but most of them are failed in implementing the law of bitcoin because we all know that bitcoin is decentralized and can control this.
That's why some are banning and some disable exchange site and banks account that related to bitcoin.
