Barring a disastrous technological or legal black swan (Gox robbed again, ECDSA broken, Bitcoin outlawed, &c), I can't imagine dipping below $5 and am willing to bet we won't dip below $12 either.
Anything else, well, we'll see. Other than
the kodiak in the room, news has generally been bullish; how these forces will play out - and whether the next major correction will take minutes or months to materialize - is anyone's guess at this point.
Except if Bitcoin is outlawed. Everything that has been outlawed in the history of human civilization has gone up in price. I expect that to hold true in case of Bitcoin as well.
