Bitcoin (BTC) Dominance broke out above 60% this week, ending an eight-month accumulation phase and targeting the 66% cycle high from June 2025. The breakout signals that capital is flowing back to Bitcoin and away from altcoins.
Momentum indicators on both weekly and daily timeframes confirm the move, while the Altcoin Season Index sits at 37. Together, these signals suggest an altseason will not arrive before the end of 2026.
The weekly chart of Bitcoin Dominance closed at 60.66%, pushing out of the green accumulation box that held price between August 2025 and April 2026. That range followed the June 2025 peak at 66.06%, when BTC.D rejected from its multi-year ascending channel.
Before the accumulation, Bitcoin Dominance respected both the ascending channel and its midline for more than two years. The underlying structure remains bullish, and the recent breakout above the 0.236 Fibonacci level at 59.63% reopens the path to the 0 Fib at 66.06%.
On the daily timeframe, Bitcoin Dominance printed its first clean move out of the 58% to 60% range that held for almost eight months. Price is now testing the resistance box around 61%, with RSI entering overbought for the first time since October 2025. MACD is also flipping green, with rising histogram bars confirming momentum.
A close above 61% would clear the final barrier before the 66.06% target. Such a move would add another 5 percentage points to Bitcoin Dominance and strip capital out of altcoins. A previous BeInCrypto analysis flagged this level as the cycle line in the sand.
Popular analyst Crypto Kaleo shared a long-term ETH/BTC chart showing the pair pressing against a descending trendline that has capped every rally since 2017. The current reading of 0.02980 sits just above the trendline, and Kaleo projects a measured move higher toward the green 0.055 zone and beyond.
His own framing contains the caveat that sinks the bullish case. Altcoins historically need Bitcoin at fresh highs before they rotate, and BTC is trading well below its cycle peak, with several traders calling for further downside into late 2026. Without a Bitcoin leg higher, the ETH/BTC base stays stuck.
