Wrong. There are several legitimate businesses that accept it as a form of tender. And there are more than a few that accept only bitcoin.

That's patently incorrect.
And it isn't safe given hacking of it.
Repeat after me. Bitcoin has not been hacked. There have been no instances of Bitcoin itself being hacked. The exchanges and markets have been hacked, yes. But that's a problem for people who didn't store their funds safely. It's like saying that the dollar isn't safe because some people had their funds stolen from/by an investment firm.

anything, truth be told.
Deal in the unadulterated facts, and if you don't know the facts and aren't willing to do research on it, then you aren't qualified to weigh in.
