is bitcoin more popular than US Dollar ?
It depends on the environment that we're talking about,
If we're talking about reality absolutely the dollar is the most popular money of all but at the level of the virtual world I think the bitcoin dominates !
But the virtual world users are also the people that's from the "reality" that you call. We all know dollars because we all know USA. Bitcoin is something that might be a "thing" on the Internet but dollars is still the leading currency here. Just take a look at how many transactions are happening in Paypal alone. That's a lot more than bitcoin. People are obsessed with using their bank account, their debit/credit card, and you use Paypal for that.

No dear Bitcoin is not more popular than US Dollar, because not more people aware about Bitcoin or even they never heard word Bitcoin, but after ransomware attack more people came to know about Bitcoin, one day may be Bitcoin in lead.
I doubt that the ransomware attack has given a lot of impact to the world. If anything, it has increased the fear of people about bitcoin. Once they see another bitcoin user, they will be reminded by the hack. Only a couple of people will try to look deeper about bitcoin after facing some fear.
