ETH/BTC Ratio

Glossary · Macro & Cycles

The ETH/BTC ratio is the price of one ether in bitcoin. It rises when Ethereum outperforms Bitcoin and falls when it lags, regardless of what either does in dollars. Because Ethereum leads the smart-contract sector, the ratio is a widely watched proxy for risk appetite inside crypto and for the start of alt seasons.

"When ETH/BTC turns up, the market is saying it wants more than just Bitcoin. When it grinds down for months, alts are dead money no matter how green the dollar charts look."

The ratio compresses two prices into one relative-strength line: ETH at $2,500 and BTC at $80,000 is 0.03125. It has ranged from below 0.02 to above 0.15 across cycles, and the multi-month trend matters more than any level — alt seasons have historically begun with a sustained turn up in the ratio while Bitcoin itself was consolidating. A break of a long ETH/BTC downtrend is one of the few macro signals with a track record inside crypto.

How to use it: as a regime filter for alt exposure. Falling ETH/BTC means Bitcoin is absorbing the flow and alt breakouts fail more often. Rising ETH/BTC widens the set of coins worth a look. Do not trade the ratio itself unless you can hold both legs; trade the regime it describes.
