This follows comments last night by Peter Thiel who compared Bitcoin to gold...

"...but the one use-case of cryptocurrency as a store of value may actually have quite a bit of a ways to go. I would be long bitcoin and neutral to skeptical of just about everything else at this point, with a few possible exceptions.

The question with something like bitcoin is whether it can become a store of value. And the thing it would replace is something like gold. The analogy is it's like bars of gold in a vault that never move and you get it and it's a hedge of sorts against the whole world falling apart."

Perhaps fear of falling apart is sparking a bid?
