I'll go out on a limb and contend a double standard exists which contributes towards crypto currencies acclaimed volatility in contrast to the exaggerated stability of fiat money. There are no fundamental nor intrinsic reasons why fiat should inherently be considered less volatile or deemed more stable. Examples of this are the current venezuelan bolivar and zimbabwe dollars of ages past. Fiat currencies have displayed far greater negative price volatility than bitcoin has in its history.
One thing we can be certain of is bitcoin should theoretically be more stable than the US dollar or any fiat due to its printing being algorithmically limited. The impossibility of bitcoin and some alts being printed out of thin air without limit should make them less volatile and more stable however there are contributing factors and unknowns which prevent that from happening. Someday perhaps when bitcoin is a more established and known phemonea, it may be recognized as exhibiting greater stability than fiat for reasons mentioned above. Crypto currencies are in their infancy and markets have a ways to go before they reach maturity.
