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.
Are you expecting at least one 10-fold move this year, though?
I think it is certainly
possible for it
not to happen (in which case this would be a lame year of anything between 500-3000% growth

) but considering:
1. bitcoin adoption rates even now,
2. and the spread of information rate,
3. and the ease of developing Bitcoin-services,
4. and the superiority of bitcoin over all the competitors
5. and the upstartness of altcoins etc etc
Everything points to me a violent upmove once the profit-taking consolidation ends.
