https://bitcointalk.org/index.php?topic=179943.0IMHO the recent "bubble" as it's been called, was from Venture Capital and other wealthy investors and they got a bit hyper. Since crash was caused by MtGox lag, they did what any reasonable person would do: wait a week and see if MtGox lag recurs. Lag is fixed, so it's back to normal slow steady rise. If we are at 140 by April 26 that's a doubling every month. Any faster and I expect more corrections.
