You're letting the massive speculative bubble up to $30, and the subsequent fall, cloud your judgement.
I don't believe that I am to a great degree. It's likely that a lot of us are allowing our hope for the solution and disgust at the current 'official' monetary systems to cloud our judgement. I try to avoid that as well.
The price falling to current levels is indicative of a change in speculative assessment, not fundamental assessment. It takes a wise, patient investor with nerves of steel to understand this and act accordingly - buying when the speculative value has dropped the market price below the fundamental value.
As I said, I continue to fill in to the USD amount I've chosen to convert. I may even up the amount (again) as I have more disposable USD and the Bitcoin network remains sound and unexploited (in a technical way.)
I am actually more than comfortable with the appearance of morbidity for Bitcoin for the simple reason that it would, hopefully, induce the crooks who have obtained their coin through theft to liquidate and create a period of time when a higher percentage of people are interested in Bitcoin were so on the basis of theory (technical and/or monetary theory that is.) More like it probably was back in the good old days a year or two ago.
