Here, we come back with a different governmental mindset. If the government dared to take the risks that exist in bitcoin as it could have disrupted the economy I'm sure the government will legalize bitcoin.
I think the government should consider the presence of Bitcoin as a global and legal currency. Due to the fact that Bitcoin is widespread throughout the world and can be used almost everyone. If in every government to do the form of legalization to Bitcoin as it is currently done by the country of Japan. I can not imagine what the price will be for bitcoin, because if every country does a legalized form of Bitcoin, of course this is the gap where every investor in the world, and will go in and invest in Bitcoin. If everyone uses Bitcoin then they have to pay taxes to the government. And this reason can lead many governments to avoid Bitcoin as a global and legal currency.
