The "fundamental" value is probably no more than 30. Most of the value is speculative, which is fine; future adoption of bitcoin is looking more and more bright
I agree that sounds about right to me.
As for Google searches, there are Google searches for Bitcoin because it has been a crazy ride and everyone is talking about it. However, I wouldn't expect that to mean another big spike. Most people even who don't invest will look at the volatility today $105-$266 and not even think about such a risky endeavor. It would be great if they were worth $1000 and a lot of larger holders sold out for profit. Then it would make manipulation and speculation more difficult. Sadly I believe that is a long time away. If Bitcoins were worth $1000 a piece then the actual usage of them at places like Silk Road would have already driven the price there. I'm curious if anyone bought and sold goods today with Bitcoin. I'm not sure how that would work but it sounds like a huge win or loss for one party or the other and not anything I'd want to do.
