BTC dominance (BTC.D) shows Bitcoin’s share of the total crypto market capitalization. This note is meant for a quick check: after a BTC.D move, is there “altseason” confirmation in Total3 and in ALT/BTC breadth? For calculation details and what the metric includes, see BTC dominance as a metric: what exactly it measures.
Goal: provide a practical way to distinguish a BTC.D decline from a situation where most altcoins are actually outperforming BTC on a relative basis.
✅ Quick check using Total3 and ALT/BTC breadth
Three steps to see whether the market confirms the move
- Compare the direction of Total3 and BTC.D over the same time window.
- Check ALT/BTC breadth across a basket of liquid altcoins and estimate what share of coins is outperforming BTC.
- Review derivatives conditions for the main alt pairs using OI and funding, and compare them with moves in Total3 and ALT/BTC.
What counts as confirmation
Confirmation for an alts scenario appears when Total3 is rising and ALT/BTC is strengthening for most coins over the same interval.
BTC.D is used as a trigger, while the decision rests on Total3 and ALT/BTC breadth.
