I believe that the paper the government has to print them on is getting more and more expensive, so it's getting harder for governments to print currency and manipulate the currency supply. And most people use online banking anyway... So why not?
Digital currency/bitcoin will never replace money and people will still use the paper money because The paper currency will never be replaced.
Exactly what people said when coins were the only currency and paper, representative money came along.
if paper money disappears, it still won't be for a very long time. It won't happen for a long time, because the government will be able to control fiat currency much easier, so bitcoin won't replace it very soon.
I agree,bitcoin wont be replacing dollar because of the government are controlling it and that is their source of power over other country.
