Volatility refers to the percentage change in the price of a financial instrument over a certain timeline. In finance, it corresponds to an index that measures the uncertainty of the performance of an asset or any asset to which a price is assigned. The term was later adopted in the cryptocurrency market to describe the unstable performance of certain virtual currencies. For example, Bitcoin is highly volatile. Since it is not controlled by institutions, its price depends solely on the supply and demand of actors within the market. Stablecoins are cryptocurrencies that aspire to avoid volatility through different kinds of pegging methods.
