Encryption rules only have to force it to track virtual currency so that monetary authorities can track any transactions that will be used for illegal purposes. The government can not regulate bitcoin globally. I hope that the bitcoin price does not continue to fall, as I just hope bitcoin will generate income and cover for my daily life. I worry, for fear of losing the other side can deal with problems during anxiety. Volatility of Bitcoins and other cryptos is too vivid. That's all I know but at present, bitcoin is still not used globally, some countries still banned bitcoin. I think bitcoin can not be adjusted because no central bank regulates it.
