Yes, there are chances that it will become popular when more people are using it and already year after year many people start buying bitcoin. It only indicates that the price of bitcoin is kept increasing because new people entering into bitcoin community.
No, bitcoin is not popular like dollar, and bitcoin can't comparison with the dollar.
Every child know about the dollar but not every young man know about the bitcoin.
I give your example, in my country only 1% people know about bitcoin out of 100%.
But dollar is too much popular in my country.
Therefore, i can't think that now and also in future bitcoin will be more popular than US Dollar.
Bitcoin Price is high, it is other reason.
