I have been thinking of this for long and the reason being that a lot of bitcoin transaction is going online everyday in many countries and i think government can generate IGR from this if possible. I am not a programmer and i have a little knowledge about bitcoin technologies but i just want to know if it is possible.
If government will place a tax on bitcoins then cryptocurrency will decrease its investors. Government can really manipulate the cryptocurrency in their country since they are the leaders, japan has really a very good decision to use bitcoins to improve their economy.
