Bitcoin dominance sits at 59.25%, signaling BTC continues to command the lion's share of crypto market capitalization. This metric measures Bitcoin's percentage of total crypto market value — when it rises, capital concentrates in BTC; when it falls, funds rotate into altcoins, often triggering "altcoin season."

At 59.25%, we're in a Bitcoin-favored regime. Historically, altcoin seasons ignite when dominance drops below 50%, sometimes into the mid-40s. Current levels suggest risk-off sentiment — investors prefer BTC's relative safety over speculative alts. This doesn't mean alts can't rally, but broad-based, explosive altcoin moves typically wait for dominance to break key support.

Actionable insight: Watch the 58% and 55% levels on the BTC.D chart. A weekly close below 58% with rising total market cap (excluding BTC) would signal early rotation. Until
