The VCs who have peddled this garbage are going to look like a bunch of frauds and fools. Not that it will materially affect them. The Cassandras who have been warning about Bitcoin will continue to be ignored, the press will still beat a door to put a microphone in front of these snake oil peddlers. With the talk of a bubble - if there is any sign of a bubble, it is a bunch of useless hashes like Bitcoin becoming worth $5-12 billion.
I suggest anyone who bought Bitcoins go read the Bitcoin FAQs of why Bitcoins are worth anything. It is complete nonsense. Moreover it is not falsifiable. It is basically "they are worth something because people think they are worth something". So even if Bitcoin crashes, that theory can still stand, since it can not be falsified. That stripe of value theorist can just say people stopped thinking Bitcoins were valuable, so their price fell.
Wise people can take the rise and fall of Bitcoin and ask real questions about where the value of commodities come from. The answer of the Bitcoin theorists, which is not that far off from mainstream economists, is a far cry from what economists like Benjamin Franklin, David Ricardo, Adam Smith thought the value of commodities came from.
I already mentioned how precious metals have retained value over millenia. Some Bitcoin advocates point to the dollar and say if the dollar retains value, why can't Bitcoin? This is a complex issue which would take too long to go into here. For one thing, the dollar does not retain its value - a dollar from today is worth much less than a dollar in 1978. Also, the conspiratorial gold bugs who say the dollar is about to collapse are probably overstating the immediacy of the problem - but that does not mean there is not a kernel of truth to their worries about paper currency. Just look at the history of currency from antiquity up until the Weimar Germany Mark to see why. No magic bullet has been found since then making the dollar bullet proof. Their worries may well be found to be correct, although probably are nothing to worry about for several decades.
