is bitcoin more popular than US Dollar ?
A big NO. US Dollar is still the most popular international currency in the world. Bitcoin is just new compare to dollar. If you ask someone in he street if they know US dollar, most answer will be yes. But if you ask them if they know bitcoin, maybe it is just 10-30% who will answer yes, most of them will say no. Bitcoin is just starting to create its own name in the world of currency. It is known by some, but seemed nothing to many people.
But the current status is changed.Bitcoin was spread among the wide range of people in this world.Even Amazon accept the bitcoin for their payment.They come to know the value of bitcoin.So like wise Bitcoin will replace the entire Dollar system in a couple of months.
