Market structure

The ETH/BTC price ratio — the canonical alt-vs-BTC internal-rotation gauge (rising = ETH outperforming BTC, the usual 'risk-on within crypto' tell).

How to read Where capital sits between the two majors right now — a rising ratio describes ETH (and, by extension, the broader alt complex) outperforming BTC.

Descriptive — strip the 'ETH/BTC rotation predicts alt-season' overlay; it describes the present internal lean, it does not forecast it.

Aggregate stablecoin circulating supply ($bn) and the Stablecoin Supply Ratio — Bitcoin's market cap divided by that stablecoin supply.

How to read The stablecoin float is present crypto-side dry powder; a rising float describes liquidity entering the system. SSR describes BTC's size relative to that buying power (low = lots of dry powder vs BTC, high = the opposite).

Descriptive — strip the 'low SSR = bottom' / 'stablecoin inflows pump price' timing overlays. Stablecoin supply is from DefiLlama's free Open API; SSR uses an approximate BTC supply.
