All thats needed is for major retailers to start accepting bitcoin as a method of payment, once this happens the MSM will have to start covering it more and then the price of BTC will EXPLODE!
Is that really what's best for Bitcoin, though? I'd prefer a lower but rock-solid price to one that was sky-high but fluctuated wildly.
Unless you were arguing the price would go high and then stabilize, which would be the best of both worlds. But once it flies up again, that would attract speculators, which might bring instability along for the ride as a consequence.
