Bitcoin (BTC) Volatility Runs at 38% Over 90 Days, 8 Times the Euro's 4.6%

38% Realized Volatility, Eight Times the Euro

The 90-day realized volatility on Bitcoin (BTC) stood at about 38% as of Thursday, a reading of how much the Bitcoin price has actually moved over the past three months, and it still leaves the largest cryptocurrency several times more turbulent than the assets institutional portfolios traditionally hold. Gold, bitcoin's oldest rival as a store of value, runs near 23.5%. The S&P 500, the biggest stock index, prints only about 11%, so bitcoin swings a little over three times as much as equities. The steadiest major asset is EUR/USD, the most liquid fiat currency pair, at 4.6%, which makes bitcoin roughly eight times as jumpy as the euro-dollar rate. The gap has persisted through a rough stretch for the euro: the shared currency of 21 countries has slid in recent weeks amid uncertainty over French government debt, yet the pair's realized volatility has stayed in single digits, in line with most fiat pairs, which hold below 10%. The closest match to bitcoin is no longer a metal or a currency but Nvidia (NVDA), the largest stock by market value, whose 90-day realized volatility runs at about 37%, so Bitcoin (BTC) and the AI bellwether now move by almost the same amount. The compression that brought bitcoin this far reflects practice as much as price: hedging and risk management in bitcoin have grown steadily more popular, trimming realized swings and making the asset more palatable to professional investors, a trend our Bitcoin coverage has tracked across cycles. Realized volatility itself is the standard deviation of daily returns, usually annualized, so a higher number means bigger swings and a stronger perception of risk. For anyone deciding whether an asset diversifies a portfolio or raises its risk, that comparison is the one that counts, and on it the claim that a fixed-supply asset already rivals paper money, the core of bitcoin maximalism, still has a long way to run.

Live readings frame where that calm sits in price terms. Spot traded at $81,688 at last check, down 0.2% over 24 hours, with the COINOTAG composite scoring the nearest resistance at $82,335 a full 100 out of 100, where the EMA 20, SMA 50 and pivot point converge, and the nearest support at $80,707 scored 65 out of 100. Positioning stays balanced: the perpetual funding rate runs at 0.0035% and the long/short account ratio reads 2.24, with 69.2% of accounts on the long side. The relative strength index sits near 47 and the trend reads sideways, so the quiet in realized volatility is showing up in the tape as range, not direction.

134% in June 2020, 27.5% Last September

History shows how far the current reading sits from bitcoin's own norm. Since January 2020 the 90-day gauge has averaged about 58%, and it peaked at 134% in June 2020, when pandemic-era liquidity shocks whipped every risk asset at once. The calmest print on record is 27.5%, reached in September 2025 as prices climbed above $100,000, so the present 38% sits closer to that floor than to the long-run average. Investors who simply hodl through drawdowns have done their part, but the bigger change is at desk level: hedging with listed instruments, from futures to the contract trading structures built on them, has become standard practice and feeds directly into the compression of realized swings. The forward-looking gauges now split from equities. BVIV, Volmex's 30-day Bitcoin (BTC) implied volatility index, is the options market's price for turbulence in bitcoin over the coming four weeks, and it remains below its 200-day moving average, pointing to expectations for relative stability in crypto. Unlike realized volatility, which only records what already happened, implied volatility looks forward, priced off demand for options and repriced at each option expiry cycle as contracts roll. The VIX, Wall Street's equivalent gauge for the S&P 500, has climbed above its own 200-day average, a sign traders there are pricing wider swings and more uncertainty in stocks. A below-average BVIV also makes protective puts and covered calls cheaper to structure, which reinforces the same risk-management loop that has been calming realized volatility. The question the divergence leaves open is how long bitcoin can stay this quiet if volatility breaks out on Wall Street.

Between the $80,707 Shelf and $82,335 Ceiling

Our reading: a 38% realized profile puts bitcoin in the same risk bucket as Nvidia, not gold, whatever the digital-gold narrative argues, and it keeps the store-of-value debate, the one Tom Lee reignited with his bitcoin-over-gold call after the $1 trillion metals wipeout, unresolved on volatility grounds. The BVIV-VIX split says the calm should persist near term, since crypto options desks price stability while equity desks pay up for protection. Price-wise, spot near $81,700 sits under the $82,335 resistance and over the $80,707 support; while that shelf holds, the sideways structure Monex Securities sketched in its $78,000 to $85,000 range ahead of the FOMC stays intact, and a daily close above $82,335 would be the first crack in it.
