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 !
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.

Let me deviate a bit from the speech by asking you if you please explain to me the story of "the ransomware attack", really every day I hear some echo about this last, I read articles and I watched videos without having a clear vision, please help me!
