I think no.USD is still over to bitcoin in terms of popularity.USD is the basis of almost all currencies around the world and its been managed by governments.Although bitcoin have many subscribers and users usd is still more popular than bitcoin.Bitcoin industry is still depending on usd currency.
USD is still better than the bitcoin, because if calculated, the USD more than the bitcoin, and not everyone knows about bitcoin. but in terms of multiplying, I prefer bitcoin, because it is easier
USD is still more used and popular but of course it will be really hard to know what will happen later in the future with Bitcoin but it is becoming more popular indeed.
But it wont take over the USD because there are still many people that dont even know what Bitcoin is and that is the problem.
