By following this logic so they shall also ban the dollar, euro, pound sterling and so on... But wait, even if it happens then what? They will use another means of payment simple as that. So to continue their trip with acid, silver, gold, copper, the diamond should be banned too.
The mainstream media always needs a boogeyman, and in this case they've found one in bitcoin, or it's a very slow news cycle. What you said is absolutely true, that the medium of exchange is not the evil here, it's the actual evil deed.
That monster Peter Scully who recently got nabbed in the phillipines in one of the worst cases of online child abuse was supposedly linked to bitcoin, though the articles I read about his case did not seem to play that aspect up. Take a look into that if you're in the mood for a horror story, but it's disgusting. Anyway, bitcoin was very early on smeared with the stain of drugs and illegal porn, and that's not likely to wash away any time soon. It's unfortunate but hopefully the average person can use a little bit of critical thinking and realize that crypto isn't a bad thing. It's all the other stuff that is, and the people who partake in it.
