The analysis focuses on the relationship between Bitcoin dominance and the ETH/BTC trading pair, two metrics that have historically signaled capital rotation from Bitcoin to alternative cryptocurrencies. Bitcoin dominance has approached a long-standing diagonal resistance line, while the ETH/BTC pair trades near cyclical lows, according to the chart data.
Historical patterns show that when Bitcoin (BTC) dominance reversed from similar resistance levels while ETH/BTC bottomed at support zones, multi-month altcoin rallies followed in both 2017 and 2021. The chart marks these reversal points with red circles, each corresponding to the start of periods identified as altcoin seasons.
The ETH/BTC pair currently sits at what the analysis identifies as a historical support area. Bitcoin dominance, measured as Bitcoin’s share of total cryptocurrency market capitalization, is showing signs of potential reversal from resistance levels, according to the technical indicators presented.
Previous altcoin seasons, marked in green zones on the chart, began when Bitcoin dominance broke down and the ETH/BTC pair moved upward from oversold territory. The current positioning of both indicators resembles those earlier turning points, the analysis states.
The cryptocurrency market has experienced selling pressure across major assets in recent weeks, with liquidity conditions remaining challenged. Bitcoin dominance and ETH/BTC alignment patterns have preceded significant capital rotation in past cycles, though no guarantee exists that historical patterns will repeat, according to market observers.
Technical analysts note that market rotations have historically occurred during periods of negative sentiment. The indicators suggest a potential setup for capital movement from Bitcoin to alternative cryptocurrencies if Bitcoin dominance reverses from current levels, similar to previous cycle transitions.
