I am a strong believer in HODL. I expected bitcoin volatility decreases as time goes by, I totally didn't expect such big price change in the past several days.
Is bitcoin volatility here to stay and not decrease?
The volatility is often measured in comparison with another asset. Often, the other asset is a fiat currency. Today's fiat currencies are usually open to monetary policy like adapting the money supply in order to protect the interests of the nation or union that issues them. Given this fundamental difference between most fiat currencies and Bitcoin, I see no way of the volatility going away when measuring it this way.
