In today's date USD is very powerful.bitcoin is gaining power though.USD and Bitcoin cant be compared as of now.bitcoin us very young but is developing at a fast rate.USD has consolidated its position in the world.
I agree, we should not compare these currencies. This is an unequal comparison. The dollar has existed for a very long time and it is the currency that the whole world enjoys. And bitcoin is a new currency, which was only born and still very few people know.
