I am not directly informed regarding this subject, so my opinion is based only on my personal assumptions from information currently available. I don't think that this Facebook scandal will amount to much. I think that we will find that the whistleblower is grossly misrepresenting the effectiveness of Cambridge Analytica and their invasion of our privacy.
You have to remember, Facebook is a social media platform. Cambridge Analytica only got access to information posted to peoples profiles. A majority of these individuals affected have profiles that are made public, which means anyone had access to that information. The only individuals whose security is truly considered "compromised" is any individuals with privacy settings.
I think that the only reason this story has gained so much traction is that of Cambridge Analytica's ties to the Trump Campaign. Facebook will release any information that was compromised and individuals will likely see for themselves that they don't really care about the leak. If you want to protect your information, don't be giving authorization to every stupid application that asks for it.
-I don't think that bitcoin plays any roll in this "Facebook Scandal" nor should it.
-If you want to talk about real invasion of privacy, we should be looking into Google Adsense.
