Why would one sell Bitcoin for Fiat right after a Mt. Gox Fueled Panic Sell-Off?

I believe Bitcoin HOLDING to even 50$ currently (and climbing), while crashing from 266$ a few days back(yes, to a 50$ low), shows the immense popularity and interest in BTC.
As soon as a few high net-worth people invest a mere 1% of their capital into BTC - watch what will happen to the price!

Hold, and be patient. And do not invest more than 1-2% of your capital, for now. As we all know, Bitcoin is still Beta.
