Bitcoin is coming up as the world currency in no time soon, it will still be more generally acceptable. For now it is not popular and trusted enough. Only those who are using it already can vouch for it and can confidently make transaction with it within themselves.
And more so to pay it to taxi driver will it have to be by digital?
what I am asking is how the value of tax is determined by bitcoin which we all know so far that the price of bitcoin is always changing in an instant, is tax at a value with the ongoing btc price?
