We are in the "early/pricing" stage of an exponentially growing (later: S-growing) phenomenon. If everything goes as it has done in several bubbles before, the great bubble will form when 1-2% of the population had adopted the technology. For Bitcoin, this means about 50 million adapters that actually use bitcoin for something. This "something" has so far been lagging, though.

I withdrew my prediction for $300 for 2013, but this does not mean that I was sure it will not happen. In 2014 it will happen for sure. Or some 1.5-sigma event happens.

The great moves have been able to push the price up roughly by an order of magnitude. We need 4 such moves and the rest of this year is not long enough time. April-June 2014 is now my target.

Current price I would just buy as much as I can.
