Two views of relative strength

Bitcoin dominance measures Bitcoin's market capitalization as a share of the broader cryptocurrency market. ETH/BTC measures the price of Ether in Bitcoin terms. They answer related but different questions.

Dominance is broad: it responds to Bitcoin, Ether, stablecoins and the long tail of digital assets. ETH/BTC is narrow: it isolates the relative price performance of the two largest established crypto networks.

Reading Bitcoin dominance

Rising dominance means Bitcoin's share of aggregate crypto market value is increasing. That can happen because Bitcoin is rising faster, falling more slowly, or because other assets are contracting. The direction alone therefore does not identify the market's absolute trend.

Reading ETH/BTC

A rising ETH/BTC ratio indicates Ether is outperforming Bitcoin over the selected interval; a falling ratio indicates Bitcoin is outperforming Ether. Moving averages help separate persistent relative trends from daily noise.

Relative-strength charts describe where performance is concentrating. They do not tell us whether the entire asset class is rising or falling.

Using them together

When Bitcoin dominance rises while ETH/BTC falls, relative leadership is clearly concentrated in Bitcoin. When dominance falls and ETH/BTC rises, participation is broadening toward Ether and potentially other assets. Mixed readings are common and often signal that market breadth is less clear.

Limitations

Market-cap estimates vary across providers, token supply definitions can change, and stablecoins can materially influence total crypto capitalization. ETH/BTC itself reflects only one relative pair. obsila therefore treats both as market-structure indicators rather than deterministic “altseason” signals.
