NYC Firefighter, Mugged And Stabbed For Bitcoin

What does this mean for bitcoin?

Nothing at all. Thieves take valuable things. Bitcoin is valuable. Nothing new there.

Do you think Bitcoin has reached so far that one have to steal the cryptocurrency physically?

It's been happening for years. Thieves will take things using any method they can.

Do you think Bitcoin is nearing the mainstream acceptance?

Just because someone was robbed? That's a strange way to determine "mainstream acceptance".

Lol...I guess If lots of ppl r being robbed off BTC..I guess BTC is becoming Mainstream. :p
