Derive.xyz Market Update: ETH $4.5K odds soar as BTC volatility stays muted
July 29, 2025 by Dr. Sean Dawson
In the last 24 hours, prices have been mostly stable across the board. ETH briefly rallied up to $3,950 before pulling back to $3,780, while BTC has dropped slightly from $119.5K to $117.8K.
BTC is expected to be more volatile over the next 90 days than the next 30. Meanwhile, ETH was predicted to have lower short-term volatility earlier this month, but this has since reversed.
This shift is evident in the 30-90 day at-the-money implied volatility (IV) spread. The spread for ETH (red line) is now consistently higher than BTC’s (blue line). A positive IV spread suggests traders expect more near-term volatility relative to longer-term (90-day) volatility.

Since May, ETH has been on an absolute tear relative to BTC. The ETH/BTC ratio has almost doubled from 0.018 BTC per ETH to 0.0325. The rise of ETH treasury companies like Bitmine and Ethermachine signals growing institutional alignment and could mark the start of a new alt season heading into Q3 2025.
