Hm, do you mean etanazir was asking about the USD? Then I might have misread the comment.
Edit: Btw, the USD is mostly has value because it's being used (useful), so yes, that's what currencies have going for them. The USD just has it so much easier as it's backed by a government.
I thought etanazir was being facetious, my bad. I guess I underestimated how many people can keep asking the same stupid question that assumes the dollar has intrinsic value while bitcoin does not. Usefulness is in the eye of the beholder.
If these people keep running around with blindfolds on, it might be time to put up some bumper walls.
