There's always a new entrant into any bubble, thinking this would be "the" ideal time :)
That said, I love the concept of BTC and could see using it at some point for some thing or other, the "investments" just give me such a sour taste that I don't even want to own any at any minor cost.
Price stability is the only way to lose the interest of the investment crowd. I think it will happen eventually, but it might be so far away that another similar currency might become preferred for exchange first.
