I never contrasted these two currencies. They're both good. Each on its own way. Each of these currencies has its drawbacks and benefits. Anyone who knows how to use both of them are very good financier
you're right both have advantages and disadvantages and I think why someone make them fight? besides using bitcoin and dollar simultaneously is not a problem. no need to compare the two, because the dollar is certainly going to win, everyone knows it. although bitcoin is no better than dolar does not mean bitcoin will die right?
