Do you really think that those big companies that are affected by the virus will be paying bitcoins to decrypt their infected files? I think they just get specialist to remove the ransomware, but I am not sure if that is even possible with this big infection from last week
If the files are encrypted, that will be next to impossible (as others have said already)
Regarding big companies paying the ransom, it doesn't as much depend on the size of the company as on the importance of files encrypted, though it would be strange for a big company not to regularly backup their important data. As the saying goes, there are two kinds of people, those who create backups and those who don't yet. Apart from that, how many big names have been really affected by this piece of ransomware?
Almost $32k received based on the current btc rate.
That's nothing in terms of impact on Bitcoin price
