Bitcoin's 90-day realized volatility has fallen to about 38%, nearly matching Nvidia's swings, according to CoinDesk calculations published 23 October 2026. That matters because steadier price moves make bitcoin easier for professional investors and portfolio managers to hold alongside traditional assets.
What actually happened
Realized volatility measures how much an asset's price swings over a set period, typically 30 or 90 days, annualized to show a full year's expected movement, CoinDesk reports. As of Thursday, bitcoin's 90-day realized volatility stood at about 38%. Gold, bitcoin's traditional rival, sat at 23.5%. The S&P 500 showed 11%, making bitcoin about three times as volatile as the index. The euro-dollar pair was steadiest at 4.6%, meaning bitcoin moved roughly eight times as much. Nvidia, the world's largest stock by market value, registered about 37%, nearly matching bitcoin. Since January 2020, bitcoin's 90-day volatility has averaged 58%, peaking at 134% in June 2020. Its calmest reading, 27.5%, came in September 2025, when prices rose above $100,000 (USD).
How we got here
Bitcoin has long been dismissed as too volatile for mainstream portfolios. Earlier this week, CoinDesk reported that risk management practices are spreading among bitcoin holders, steadily reducing swings as the 'just bet on price' trading style fades. That shift follows years of extreme moves, including bitcoin's 134% volatility spike in June 2020 during pandemic turmoil. Institutional adoption, exchange-traded fund inflows and more hedging tools have gradually smoothed price action since then. The current comparison to Nvidia, itself volatile because of AI spending concerns that recently dragged down the Nasdaq, shows bitcoin now trades more like a high-growth tech stock than a currency.
Why this matters for you
For holders, lower volatility could mean steadier portfolio value and fewer forced liquidations during sharp swings. For institutional investors, a 38% volatility reading, close to a blue-chip stock like Nvidia, may ease approval processes for allocating funds to bitcoin. For builders in wallets, exchanges and AR or smart glasses apps that display live price data, calmer markets mean more predictable user experiences and fewer panic-driven support spikes. Still, bitcoin remains roughly eight times more volatile than the euro-dollar pair, so it cannot yet substitute for a stable currency in everyday payments or merchant settlements. Users expecting bitcoin to behave like cash for daily spending should temper those expectations.
The bigger question
If bitcoin's volatility keeps converging with large tech stocks like Nvidia, does it still function as an alternative to traditional currencies, or has it simply become another high-beta equity substitute? The answer could shape how regulators, pension funds and sovereign wealth managers classify bitcoin going forward, and whether its limited supply alone justifies its place in a diversified portfolio.
What to watch
Watch CoinDesk's 90-day realized volatility gauge for further convergence with, or divergence from, Nvidia and the S&P 500 in coming weeks. Traders should also track the Bitcoin Volatility Index, BVIV, against Wall Street's VIX, since BVIV remains below its 200-day average while the VIX has climbed above it. Bonuz will track how this trend affects demand for real-time price displays on wearable and smart glasses apps.
