That's incredibly stupid. They present no evidence, and here's the quote they lead with:
> “If I was looking for a store of value, I'd buy gold, wouldn't I?” Edward Castronova, a professor of telecommunications, and an expert on virtual worlds and currencies, told Ars. “It's a hell of a lot safer than Bitcoin.”
Castronova, have you ever heard of things like 'margins' or 'fungibility' or 'walking and chewing bubblegum'? You know, people can buy both bitcoins and gold - shocking as this may seem. The question is not 'are people physically on the island of Cyprus who would be buying gold instead buying bitcoins?', the question is 'on the margin, are people worldwide buying bitcoins because of Cyprus?'
Nor is pointing out the recent rise an objection. The rise over the past months to $30 was relatively slow and gradual. The rise to $50 and then $105 has been meteoric and directly correlates with the sudden Cyprus crisis. Bitcoin literally started with criticism of bank failures and bailouts (check out the first block, by Nakamoto, in the blockchain) and immunity to this sort of shit is one of its main selling points. The burden of proof is on anyone who thinks that Bitcoin has suddenly just sorta accidentally tripled for no reason at all relating to Cyprus.
