Bitcoin's 90-day realized volatility registered 38 percent as of Thursday, matching Nvidia's 37 percent volatility and signaling the cryptocurrency is now moving in sync with major technology stocks.

The metric measures annualized standard deviation of daily returns. Higher percentages indicate larger price swings and increased risk perception.

Bitcoin's volatility towers over traditional assets. Gold trades at 23.5 percent, the S&P 500 at 11 percent, and EUR/USD at 4.6 percent—meaning Bitcoin is roughly eight times more volatile than the world's most liquid fiat pair.

The stabilization represents a dramatic shift from Bitcoin's historical baseline. Since January 2020, the cryptocurrency averaged 58 percent 90-day volatility. It peaked at 134 percent in June 2020. The calmest reading came in September 2025 at 27.5 percent, a period when Bitcoin's price surpassed $100,000.

The convergence with Nvidia-level volatility matters for portfolio construction. Professional investors have long treated Bitcoin as uncorrelated to equities, but this data suggests that narrative is aging. A mega-cap tech stock's volatility now describes the largest cryptocurrency—a marker of how institutional capital has embedded itself into the asset class.
