I skimmed quickly, but didn't see anyone bring up this point:
Right now, we're dealing with inflation of 50 BTC per 10 minutes.
For the year, we're gonna go from 8 million BTC to 10.5 million BTC (ish), so more than 25% annual inflation, yet the price seems to be stable. This implies that people are obtaining BTC at a pace that keeps up with this inflation.
Next year, inflation will be smaller for two reasons:
1) block reward cut in half to 25 BTC per 10 minutes &
2) For 2013, BTC will go from 10.5 million BTC to 11.75 million (ish), so less than 15% annual inflation.
If people continue to obtain BTC at a pace that keeps up with 25% inflation and yet inflation drops to less than 15%, then this will give upward pressure (where now we see flat or upward pressure on price).
Bottom line is that the economic statistics that give us moderate or even flat price growth could give us higher growth in future years if the underlying behaviors continue. Will they continue? Now that's a question for great speculation
I'm putting my money on yes. and I believe they will even grow, but now back to developing the bitcoin economy...
Someone feel free to post the more accurate numbers; I threw these out off the top of my head, but you get the idea. I'm just trying to show the directional movement.
