While I believe that the initial floor of $2 a couple of months ago, and the following slow rises to $3 or so are justifiable based upon fundemental metrics related to the bitcoin economy; the most recent spike to $6+ is unfounded and indicative of a rising mania. The growth of the bitcoin economy simply hasn't had the time to keep up with that kind of runnup.
I sympathize with your sentiment. I would love to see Bitcoins trade and grow in value in a slow, steady way. But as the last week as shown, the Bitcoin market is really based on speculation and manipulation.
You can go with the flow and hope to make out when she skyrockets into double digits, or you can sit it out and preserve USD if and when Bitcoins comes tumbling down.
I got out recently and made some profit. You had to know the $7.20 plateau was not going to sustain. The last time we had a 1/2 day of steady pricing we were at $6.20. Maybe we are still correcting into a new trading range, but this recent volatility is keeping some folks out, me included.
