I still think the google trends for "bitcoin" searches to be a good leading indicator, a methodology that's been rigorously examined for flu and other health trends. Search volume this week is almost 50% higher than the last peak two weeks ago. Add in the 5500 person approval queue at Gox, the re-launching of Tradehill for accredited investors only, and the fact that people love round numbers like $100, and I think we'll be at $120 in the next week, with $100 as the new floor. In short, I don't think this is a bubble yet.
Another round of articles will happen when the $1B market cap is passed at $91. And in other news, today Apple dropped from an open of $456 to $452, losing about $4B in market cap this morning.
