The question of what happens with bitcoin if a "great recession" happens is an interesting one, since it hasn't been tested yet. I have a feeling that if a global meltdown occurs and mass unemployment is a component of that, people are going to sell bitcoin en masse and the price will probably fall significantly--and all of the altcoins that people are now hoping to get rich on today? They're going to fare even worse.
I don't see bitcoin as a safe-haven asset like gold or silver. It's way too volatile for investors looking to preserve the value of their money when markets go haywire, and if we do get an economic disaster a-knockin' at our door my bet is that metals will start rising again.
