Current BTC dominance: 58.37% - this is relatively high. Historically, altcoin season tends to happen when BTC dominance drops below 50% or even 45%. At 58.37%, we're still in BTC-dominated territory.

Let me write this out and count words.

Draft:

Bitcoin dominance at 58.37% signals the market remains firmly in BTC's grip. This metric measures Bitcoin's share of total crypto market cap — when it rises, capital flows into BTC as a safe haven; when it falls, traders rotate profits into altcoins seeking higher beta.

At current levels, we're far from classic altcoin season territory. Historical patterns show alt seasons typically ignite when dominance breaks below 50%, often accelerating under 45%. With BTC holding near 2021 highs, the rotation gate stays closed. ETH at 11.49% dominance also reflects muted alt appetite — the second-largest asset isn't leading a broad rally.

This doesn't mean alts are dead. Selective opportunities exist in narratives with real traction (AI, RWA, DePIN). But broad-based alt rallies need dominance erosion first.

Actionable insight: Watch the 56% level on weekly closes. A decisive break below with rising total market cap (ex-BTC) confirms rotation momentum. Until then, size alt positions smaller and keep stablecoin
