Yes the actual volatility calculation is better but my numbers illustrate my point which is that the price is by no means stable in an absolute sense. We are in a "quiet period" relative to what happened during a massive bitcoin bubble but even the site you linked indicates that the volatility is twice that of gold and approximately three times that of major currencies even though we're in a quiet period. Also note that the site is measuring historical volatility instead of implied volatility as is customary for most financial instruments so it can't be compared one-to-one with VIX or similar measures.
