thank you very much for your good presentation.
during the last three month bitcoin's price volatility is low, but we see chinese policy December last year and MT.Gox caused price breakdown.  All of this attributes to goverment regulation, at these situition, its price is not stable at all. it will happen again.

if the bitcoin market keeps the pace of recent two month, BTC will make a big step to be a stable currency.
another hand, lots people suggest there will not be this kind of stable, and they have reasons because the limited bitcoin supply, they(include me) think the price will rise steadily in the long term.

expectation of steady rise and stable in price is a contradiction?
