What ETH/BTC says today
On October 16, 2026 one ETH buys 0.02979 BTC: Ethereum trades at $2,446.34 and Bitcoin at $82,115. Against Bitcoin, ETH has returned -1.5% over 7 days, -6.0% over 30 days, -1.7% over 200 days, -17.3% over one year.
The 30-day Altcoin Season Index reads 64/100 and Bitcoin dominance is 59.3% on the same date. Most tracked altcoins are ahead of Bitcoin while ETH is not, so the move is being led from outside the largest altcoin.
Since July 14, 2026 the ratio has ranged from 0.02873 (July 18, 2026) to 0.03275 (August 19, 2026).
ETH/BTC is the price of the largest altcoin in Bitcoin terms, so it moves before or without the rest of the market. A rising ratio with a low index means Ethereum alone is outperforming; a rising ratio with a rising index is what a broad rotation looks like.
