So, the exchanges have been keeping a fairly tight band around $5/BTC, I'd like to hear opinions on how much you attribute this to the following factors:


1) Fundamentals: economy is growing at the same rate of the influx of coins from mining so prices stay constant
2) Price stickiness: optimal trade would occur at a different rate but either hoarding or excessive selling is keeping the price up or down
3) Price comfort: easy to think of bitcoin rate as divide USD by 5, works well with our decimal system
4) Other factors, please describe...
