## When to prefer this

Use this endpoint when you need to identify potential cycle bottoms in Bitcoin or Ethereum markets by combining supply-in-profit dynamics with price volatility. It is ideal for on-chain macro analysis, risk assessment at market lows, or systematic bottom-detection strategies. Prefer this over generic price feeds when you need a composite exhaustion signal backed by Glassnode's proprietary on-chain data.
