A crypto analyst is flagging a potential turning point for altcoins after identifying an eight-year convergence pattern on the Ethereum–Bitcoin (ETH/BTC) chart that could presage a major altcoin season.
Analyst CW shared the thesis on X, pointing to a multi-year structure on the weekly ETH/BTC chart that has been forming since mid-2017. The pattern looks like a large descending triangle or wedge: a long, sloping resistance line that began when ETH/BTC hit a peak around 0.16, and a flat horizontal support that has held roughly near the 0.020 zone. Over the past cycle ETH/BTC failed to clear the upper trendline during the 2021 rally and subsequently slid lower. Now, CW notes, the pair is compressing into the apex of that structure—around the 0.029 area—suggesting the eight-year compression could be reaching a climax.
Why it matters: a decisive breakout from this wedge would imply a shift in market leadership away from Bitcoin and toward Ethereum — and potentially into the broader altcoin market. CW argues that such a breakout could kick off an altcoin season that eclipses the 2021 cycle and approaches the breadth and ferocity of the 2017 boom, when altcoins produced the widest and most aggressive gains across the market.
CW bolsters the technical view with on-chain/exchange data. He reposted a CryptoQuant chart tracking the CEX volume ratio of non-BTC assets versus Bitcoin (excluding stablecoins), showing sustained altcoin trading activity that has been elevated for longer this cycle than during the 2021 run. That persistent volume, he suggests, increases the odds that a technical breakout in ETH/BTC would be accompanied by broad capital rotation into altcoins.
Bottom line: traders and analysts will be watching the weekly ETH/BTC structure and centralized-exchange altcoin volumes closely. If CW’s read plays out, the end of this long compression could mark the start of a powerful altcoin season in 2026 — though, as always, technical patterns are probabilities rather than guarantees.
