BTC dominance is the most reliable macro clock in crypto and right now it deserves close attention.

Bitcoin dominance measures BTC market cap as a share of total crypto market cap. Historically, it follows a predictable cycle:

1. Bear market bottom: BTC dominance rises as capital flees altcoins, parking in relative safety
2. Early bull: BTC leads the charge, dominance stays elevated or climbs further
3. Mid bull: ETH starts outperforming, dominance peaks and begins rolling over
4. Late bull: dominance collapses as capital cascades into mid and small caps

The critical signal is not the absolute dominance number. It is the rate of change. When BTC dominance breaks below a rising support line with real volume behind it, that is historically one of the cleanest altcoin season entry signals available.

What makes this cycle unique: spot ETF inflows have structurally elevated $BTC perceived safety premium. Institutional buyers defaulting to Bitcoin as their first on-ramp means dominance may stay elevated longer than prior cycles before the rotation trade opens up.

For $ETH and $SOL holders: patience matters more than ever. Rotation will come, but the trigger is a genuine dominance breakdown, not just altcoins moving sideways while Bitcoin grinds higher.

Watch the dominance chart. It tells you where we are in the cycle before price does.
