I see that the more bitcoin the more users seen from the significantly increased bitcoin price increase, is this a sign that bitcoin will soon become the future virtual currency?
Yes, and it is also a good sign. This will bring profits to those people who holds a huge amount of bitcoin. But, I think the government will not let bitcoin replace fiat money since fiat money makes ups banks and banks are under the government. Nevertheless, we cannot be sure what changes will happens in the future but we better be ready for it.
