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!
I really wouldn't blame you for not understanding what was the ransomware attack because there's not that much people that you can talk to about it. There are some "tech savvy" guys out there that pretend what's going on and they act like they are all familiar about the attack but don't even use bitcoin or encrypt their files. The ransomware attack has encrypted
[1] the files of users (Windows operating system) and you will see a message saying that you have to deposit bitcoins to the given address before they give you the decryption key. It has happened worldwide and was on the local and international news so no wonder why everyone talked about it.
[1] Meaning: You can't use your files unless you decrypt it with the right key. Encrypted files are basically like files that have password that you have to put.
