Crypto market observatory: what the numbers actually say
Everyone has an opinion about crypto volatility. We have the data. This page runs 54 days of real OHLCV data (CoinGecko) on Bitcoin, Ethereum and Solana through a few simple calculations: which asset moves most, how tightly they track each other, which days of the week are wild, and the period's records. Every figure is recalculated automatically as our daily data grows.
Comparative volatility: BTC, ETH, SOL
Two complementary measures. The average daily move (absolute value of the close-to-close return) tells you how much the asset changes from one day to the next. The average intraday range (the day's high minus its low) tells you how choppy the day itself is. That is the measure that matters if you trade intraday.
| Asset | Average daily move | Average intraday range | Green days | Period perf. |
|---|---|---|---|---|
| Bitcoin (BTC) | 1.51% | 3.08% | 36% | -27.0% |
| Ethereum (ETH) | 1.94% | 4.04% | 40% | -31.9% |
| Solana (SOL) | 2.42% | 4.90% | 38% | -20.0% |
How to read this: over the period, Solana's average daily move is 2.42%, against 1.51% for Bitcoin. That matters for position sizing: at equal risk, a SOL position has to be much smaller than a BTC position. It is the correction the position size calculator applies with the 1% rule.
Correlations: holding 3 cryptos is not diversifying
The Pearson correlation of daily returns measures whether two assets move together (1 = perfectly together, 0 = independent, -1 = in opposite directions).
| BTC / ETH | 0.87 |
| BTC / SOL | 0.84 |
| ETH / SOL | 0.87 |
With an average correlation of 0.86 between the three assets, splitting your capital across BTC, ETH and SOL barely reduces risk: the day Bitcoin drops hard, the whole portfolio goes with it. What actually protects you is sizing and stops, not spreading across three coins that move as one. We cover this in detail in the risk management guide.
Volatility depends on the day of the week
Aggregate the intraday ranges of all three assets by day of the week (UTC) and the pattern is obvious: weekdays move, weekends are quiet.
| Day (UTC) | Average intraday range (BTC+ETH+SOL) |
|---|---|
| Thursday | 5.00% |
| Friday | 4.83% |
| Monday | 4.76% |
| Tuesday | 4.42% |
| Wednesday | 3.86% |
| Saturday | 2.87% |
| Sunday | 2.53% |
On average, Thursday shows 2 times more range than Sunday. Crypto trades 24/7, but liquidity follows institutional desk hours. It is the same mechanism behind the Killzones intraday: trading on a Sunday means tight ranges and breakouts that fail more often.
The period's records
- Bitcoin: best day +3.93% on June 8, 2026, worst day -6.60% on June 3, 2026.
- Ethereum: best day +7.54% on June 8, 2026, worst day -10.7% on June 6, 2026.
- Solana: best day +6.56% on June 8, 2026, worst day -8.83% on June 3, 2026.
The worst single day of the period belongs to Ethereum, at -10.7% on June 6, 2026. Keep that number in mind when sizing a leveraged position: days like that hit with no warning, and they are what blows up over-exposed accounts (see how liquidations work).
Methodology
Source: CoinGecko daily OHLCV data (open, high, low, close, volume), collected every day by our pipeline and archived in our daily Bitcoin analyses (Ethereum, Solana). Daily returns are computed close to close; the intraday range is (high − low) / low; correlations are Pearson correlations of daily returns; the day-of-week statistics aggregate the ranges of all three assets in UTC. Covered period: May 9, 2026 to July 1, 2026 (54 days). The figures on this page are regenerated automatically with every data update, so they can differ slightly from one snapshot to the next. That is expected.

Frequently asked questions
Which crypto is more volatile: Bitcoin, Ethereum or Solana?
Over the last 54 measured days (May 9, 2026 to July 1, 2026), Solana is the most volatile of the three, with an average daily move of 2.42% (close to close), versus 1.94% for Ethereum and 1.51% for Bitcoin. In other words, Solana moves about 1.6 times more than Bitcoin on an average day.
What day of the week is the crypto market most volatile?
Over the measured period, Thursday is the most volatile day, with an average intraday range of 5.00% (BTC+ETH+SOL average), while Sunday is the quietest (2.53%). That is a gap of roughly 2 times. On weekends, without institutional flows, ranges shrink hard.
Are Bitcoin, Ethereum and Solana correlated?
Yes, strongly. Over the measured period, the correlation of daily returns is 0.87 between BTC and ETH, 0.84 between BTC and SOL and 0.87 between ETH and SOL. In practice, holding all three barely diversifies anything: when Bitcoin drops, the rest drops with it.
Where does the data behind this observatory come from?
From daily OHLCV data (open, high, low, close, volume) provided by CoinGecko, collected every day by our automated pipeline and archived in our daily analyses. Returns are computed close to close, and intraday volatility uses the range (high minus low, relative to the low). Every statistic on this page is recalculated automatically whenever the data is updated.
How often are these statistics updated?
The underlying data is collected daily and the page is recomputed on every site deployment. The covered period is shown at the top of the page; latest data point included: July 1, 2026.
