Altcoin season is accelerating as Bitcoin dominance (BTC.D) slips below a long-term rising trendline. This breakdown suggests liquidity is rotating into altcoins, and historical market cycles show alts frequently outperform Bitcoin during such rotations.
What caused the Bitcoin dominance breakdown?
Bitcoin dominance broke a clear rising trendline that had supported BTC.D for nearly two years. The trendline break is a technical confirmation of capital shifting, and it often precedes periods when altcoins gain relative market share versus Bitcoin.
How does capital rotation fuel altcoin season?
Capital rotation occurs when investors reduce Bitcoin exposure and allocate to altcoins, increasing altcoin trading volumes and price momentum. Market indicators, including altcoin season indexes and on-chain flow metrics, show rising alt activity.
Market commentator Merlijn The Trader noted the breakdown and stated that rotation has arrived. Plain-text source mentions: Merlijn The Trader (Twitter). Historical patterns and index readings (CoinMarketCap altcoin indexes) support the interpretation that reduced BTC dominance often leads to multi-stage alt rallies.

Why do large-cap altcoins often lead initially?
Large-cap altcoins typically receive the first wave of rotation because they offer higher liquidity and lower slippage than smaller tokens. As traders seek exposure beyond Bitcoin, they often favor established altcoins, which can then attract momentum traders into mid- and small-cap markets.
Index readings show altcoin season momentum around 61, approaching the commonly watched 75 threshold that historically signifies full altseason. This staged progression—large-cap, mid-cap, then small-cap—matches prior cycles documented in market data (plain text source: CoinMarketCap altcoin indexes).

When should investors consider reallocating from BTC to altcoins?
Investors often consider reallocation after a confirmed BTC.D breakdown, rising altcoin index readings, and increasing alt volumes. Short-term entries can target leading large-cap alts while monitoring momentum and liquidity metrics for safe scaling into mid- and small-cap opportunities.
How to identify favorable entry points during rotation
- Confirm BTC.D trendline break and watch for follow-through closes below the trendline.
- Monitor altcoin index momentum and trading volume increases.
- Use staged allocation: initial exposure to large-cap alts, then incremental exposure to mid/small caps as momentum confirms.
Frequently Asked Questions
How long does an altcoin season typically last?
Altcoin seasons vary, lasting weeks to several months depending on macro liquidity, on-chain flows, and market sentiment. Historical cycles show staged expansions that can continue while BTC consolidates.
Is this rotation bullish for the overall crypto market?
Rotation from Bitcoin into altcoins is often bullish for the broader market as liquidity redistributes and more tokens see price discovery. However, risk and volatility typically increase during deep altcoin rallies.
Key Takeaways
- Trendline break matters: BTC.D breaking a long-term trendline confirms rotation into altcoins.
- Staged rallies: Large-cap alts tend to lead, then mid- and small-cap tokens accelerate as momentum builds.
- Monitor indicators: Use BTC.D, altcoin index readings, and trading volumes to time allocations and risk management.
Conclusion
Bitcoin dominance falling below key support signals an active altcoin season, with liquidity rotating into altcoins and early opportunities appearing in large-cap altcoins. Track BTC.D, alt indexes, and volume metrics to manage risk and position for potential multi-cap rallies. COINOTAG will continue monitoring these signals and publishing updates.
