Is Bitcoin the new gold?

Some former gold bugs certainly think so.

And its value has skyrocketed in recent months.

Robert McNally, an iOS developer at parking payment startup QuickPay, gave the following presentation to last year's Hackers' Conference in Santa Cruz, answering exactly that question.
