I can see the fear starting to spread as the reality that we won't be right back to $100+ in the short-term. I can feel it myself as I have to convince myself to stay in and do my part for strengthening the ecosystem. It's interesting to be a part of this as there is a faith-based aspect which I don't exercise very often. We all hope (at least most) that the price will rise sooner than later, we just have to make due with what we've got right now.
If I was willing a few days ago to buy at $100, then I can only see this as a good thing. I'm getting the bitcoins that I buy at a MUCH cheaper cost than I was already willing to pay. How valuable they are to me is not dependent upon how valuable they are to the people who are buying and selling at MtGox (or any other exchange). I know how much I'm willing to pay for them. Anything less is a great discount. Anything more and its time to stop buying and just hold on to them or spend them where possible. I adjust my opinion about value based on their security, and utility.
