Remember that never before in the history of mankind a new currency came on the market so suddenly and right there for everyone to pick up for a bargain. Once the banks and governments of this world find this out, there will be a race to get in on it as fast as possible. This will be the tipping point, where we can expect to see an exponential increase in value. As long as this point has not been reached, it is incredibly silly to worry over a few dollars in a few weeks.
You may well be right in most of what you say here but your time-scales will probably be well wrong. Mega-banks and govt.s are not going to be hopping on to any "crypto-currency" band-wagon any time soon and the infrastructure does not yet exist inside bitcoin world to support them anyway. That is not to say that they never will however.
The great thing about this experiment is the little people can enter first, and to the fullest they wish to risk, but the big guys have to wait ....
".... it is easier to fit a camel through the eye of a needle".
Just by the logistics involved, the system will grow naturally and the size of entrants to the system will be commensurate to the size of the system at the time.
It will look like an exponential singularity if it all pans out, but you will have to look back from 2035 and scale the chart accordingly.
On the little details, I think we are in a rather powerful wave 3 of 2, heading for a re-test of $32 June 2011 high from first wave up. I'm expecting a blow-off to the $25.88 area and collapse back to re-base around $20.8 region ... fwiw. (Longer term in an unknowable time-frame waves 4 of 2 and 5 of 2 should takes us past the $32 to finally top out around $51.7.)
