I bought more near the peak that I've have liked (I'll blame that on severe Dwolla delays) but the worst thing I could do now is to sell.
Think in terms of months, not days. Your money is most likely fine. We "double" all the time, it would be ludicrous if that didn't work the other way and "halve" occasionally as people cash out en masse. Speculators spreading obvious FUD were just after your money guys.
