I too am curious to know why a rise in price is perceived as a problem.
Use as a medium of exchange is critical to Bitcoin's long-term success. Instability in value makes a currency harder to use as a medium of exchange. Imagine, for example, if you placed a large purchase on a Bitcoin credit card and the value of Bitcoins doubled. Or imagine if your rent was in Bitcoins and then the value of Bitcoins doubled.
Part of using something as a medium of exchange is you hold those things to plan for future purchases. If you're paying rent in BTC and holding dollars, you're doing it wrong imo.
Anyways, Bitcoin is used by a tiny amount of people right now. You're not gonna get to the point of "long-term success" without it going up a bunch.
