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
They are certainly both good especially for us who uses bitcoin, because we need to convert bitcoin with USD and that is what the bitcoin is depending its value. And if we will just combine them both they will going to be a very powerful type of currency that has being used worldwide. I hope to see that bitcoin was being used by billions of people living in this world.
combining both is impossible because both are currencies which getting used in different world,and you don't really need to always convert your bitcoin to USD,just convert it directly to your local fiat on your local exchangers and everything should be fine
