I followed stories surrounding computer security for a couple of years off twitter for my own amusement, and I have zero faith in computer security and privacy. Somehow, crypto currency doesn't seem appealing to me. Admittely, I don't really understand its appeal so I don't have much to say in that regard.
I swear I've heard some time ago, that with this one OS, at login, pressing the "back" key five times would bypass the login because of bad code implementation or who-knows-what. And in the bushes, lurks the NSA et al, collecting your politician's freaking DNA, finger prints and whatnot.
I truly fear that the future will be a combination of a police state similar of today (imo dubbed "surveillance state" by those that feel more comfortable with using that label as opposed to 'police state') and most things monitored and backdoored.
