Dude, bitcoin hasn’t been seen as taboo for many years. Most of us here are good people simply using it as a tool for payment & or an investment.
That's just here, on the forum. It's usually associated with the darknet and the darknet is usually associated with "red rooms", "black markets", "hackers" etc. The image most have in their mind when you mention "Bitcoin" out loud is in almost every case one about some criminal activity. Unless you do a bit of research (which is just a Google search really), you'd have this idea from the MSM.
