If the OP is correct then why does silver (a market which is about 5% that of gold) have daily volatility about 800% of that compared to gold (silver's relative beta is 8.0 compared to gold).
Larger markets are less volatile markets.
How do you think the exchange rates between major currencies pairs have so little volatility? Any guess on how huge the forex market is? Got a guess. I will give you a benchmark. The world GDP is $75 trillion .... got your guess now (you probably aren't even close) scroll down.
It is ~$1,800 trillion. That's right 1.8 quadrillion dollars annually to stabilize a global economy of $75 trillion. There are no small stable markets ever. Small and stable never go together. Bitcoin even at $10B is tiny compared to even silver ($550B) and silver is considered highly volatile as a "small" market compare to gold which is nearly 16x larger (~$8,000B) or 800x larger than Bitcoin. When Bitcoin is 800x larger it will take tens of billions of dollars to move the market a couple % and as result outside of huge events it won't move more than a couple percent.
edit: Having said this. We must be diligent to use the tools of math to find our own "realistic value" of Bitcoin. Rolling averages help with that.
