Normally speaking, taxes are normally being collected by government in such differet countries, the legality of a certain businesses are undergo with a tax payment. So, if bitcoin will pay taxes or government force to collect taxes from bitcoin owner supposedly bitcoin become legal and endorse by government. If we are a normal citizens on our living country, we must pay taxes without any persons force us to pay, it is our rule to support our government by paying taxes so that our country economic system developed. The economic system in every country's are base on a taxes being collected, without payment of taxes it will result economic shutdowns.
Yes I like to pay tax because a civilized nation they are always believe to give tax its such an important thing to give if you will not give tax so your country can be destroyed financially and there are some countries who are suffering very badly because their people they dont give tax so if bitcoin users also start giving tax so believe me it will change a country economy very fast and Im sure it will be started very soon because bitcoin is a fast growing currency.
