What is

The Bitcoin Volatility Index is used for tracking the Bitcoin price volatility in US dollars over different periods of time.

What is volatility and why does it matter?

Volatility is a measure of how much the price of an asset varies over time. Volatility refers to the amount of uncertainity or risk about the size of changes in a finacial asset's value. A higher volatility means that the price of the asset can change dramatically over a short time period in either direction. A lower volatility means that a financial asset's value does not fluctuate dramatically, but changes in value at a steady pace over a period of time. If Bitcoin volatility decreases, the cost of converting into and out of Bitcoin will decrease as well.

How does calculate the volatility?

It uses the standard deviation of the daily closing price for the preceding 30-, 60-, 120- and 252-day windows. These are measures of historical volatility based on past Bitcoin prices.

Which sources are used by this website? currently uses the CoinDesk API for querying data used in the volatility calculation. Furthermore, it uses the BitStamp API for querying the current price. Both sources may change in the future.
