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.
I believe the Bitcoin name is just dragged on these things. Criminals will use everything just to do their bidding and sadly, they found Bitcoin or other cryptocurrencies to do their bidding much easier. And this criminal activity associated with Bitcoin was already in the past. We can see Bitcoin now associated with legal merchants and accepted by the open-minded government.
Aside from that, Bitcoin is seen by people not only here in the forum as a mode of payment and I think, there is much more people outside this forum who use it as payment. Btw, isn't fiat currency have higher cases when it comes to corruption and criminal activities?
