Altseason Confirmed After BTC Dominance Rejection
Bitcoin dominance hit its upper resistance trendline in early July 2025 before reversing—a pattern seen in 2017 and 2021. Each rejection at this level historically marked the start of altcoin rallies. Key observations:

Golden Cross on Altcoin Market Cap
A rare golden cross (50-day MA above 200-day MA) appeared on the altcoin market cap—a setup last seen in 2021, preceding 123x rallies. Context strengthens this signal:
- Follows a prolonged accumulation phase with higher lows since Q1 2025.
- Spot market activity suggests organic capital inflow, not speculative hype.
$OTHERS.D Retests 2014 Trendline
The $OTHERS.D chart (dominance excluding BTC/ETH) retested a decade-long trendline in 2025—a level that triggered multi-month altcoin rallies in 2016 and 2020. This bounce aligns with:
- Broad capital rotation into mid- and small-cap altcoins.
- Early signs of market share recovery outside BTC/ETH.
Historical Patterns and Projections
Comparing 2025 to past cycles:
- 2019 and 2021 fractals suggest breakout phases precede exponential gains.
- Altseason cheat sheets project expansion paths into 2026 based on past symmetry.
