No.But it has started to gain popularity slowly.US dollar has been as Global reserve currency for the past 70 years.Petrol is sold only in US Dollars.US dollars can be exchanged universally in any country.But bitcoi has just crossed its initial eight years.There are more people who dont even have bank account and dont know about credit card and digital transactions.But bitcoin is a digital currency.So it would take years for bitcoin to get popularity more than US dollars.
