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.
You'll just discourage people to use bitcoin with that outrageous fee. I envy countries who don't tax bitcoin profits like in Germany and I wish it happen in my own land. Government can still tax us when we use bitcoin to pay things by putting it in oil, goods, and things that we normally purchase.
Government and people are contradicting each other because of Bitcoins high volatility. I personally think 30% tax is too much for the government to ask, considering how volatile Bitcoin is.
I am not against regulation, but what I am afraid of when regulations are being implemented around the globe, is the possibility for the tax being abused.
