I think any of the big dumps in the past few days on the exchanges would have caused a panic sell like April if there was not enough support for the price.  We are at the base of an S-curve.  Everyone should be studying exponential growth to get an idea of where we are headed and to get an understanding of why it is increasing so fast.  The more people that find out about Bitcoin the faster the price will rise.  It is common with any new technology adoption.  If we think this is crazy, next year will be even crazier I believe.  Sure, there will be a few bumps in the road here and there but we will never see anything below $100 again at this point.  I would even venture to say that now that we have "stabilized" a bit here in the $400 range for a few days that the $200s are gone for the most part.  Maybe there will be a day when it dips down for a few minutes but those coins will be bought so fast that it will be hard to catch them.  Just my thoughts.
