The volatility of Bitcoin has witnessed a noticeable decline in recent years, and is currently approaching the level of volatility recorded in Nvidia stock, while it remains about eight times more volatile compared to the EUR/USD pair, according to data from the “CoinDesk” platform.
The data showed that the achieved volatility of “Bitcoin” over 90 days amounted to about 38%, very close to 37% for “Nvidia” stock, which reflects the movement of the cryptocurrency at a pace similar to one of the most prominent technology stocks in the world. The realized volatility index measures the size of an asset’s price movements over a specific period of time based on the standard deviation of daily returns converted to an annual rate. The higher its reading, the greater the severity of the changes and the level of risks associated with holding the asset.
In comparison with other assets, the volatility achieved for gold reached about 23.5% during the same period, which makes Bitcoin more volatile than its traditional haven as a store of value. As for the S&P 500 index, it recorded fluctuations of about 11%, which means that Bitcoin’s movements exceed approximately three times the fluctuations of the US stock index, differences that directly affect portfolio management strategies, diversification and risk decisions.
In terms of traditional currencies, the euro-dollar pair remained the most stable, recording achieved fluctuations that did not exceed 4.6% within 90 days, and thus Bitcoin’s fluctuations exceeded this dice by about eight times, despite the pressures that the euro faced following the French debt crisis. In general, the majority of traditional currency pairs record fluctuations of less than 10%, highlighting the gap that separates “Bitcoin” from the stability of currencies used in daily transactions.
Despite the continued difference with traditional assets, the data confirms a clear improvement in the stability of the cryptocurrency compared to its historical performance. Its average volatility for 90 days reached about 58% since January 2020, recording a peak of 134% in June of the same year, compared to the lowest level of volatility of 27.5% in September 2025, coinciding with the price exceeding the $100,000 barrier.
In a related context, the implied volatility index for “Bitcoin” stabilized for 30 days below its 200-day moving average, which indicates traders’ expectations of relative stability in the market, while the “fear” index on Wall Street exceeded its 200-day moving average, reflecting expectations of increased volatility in American stocks, so that “Bitcoin” eventually stabilized behaviorally near major technology stocks, while keeping it a distance from the stability of gold, currencies, and broad indices.
