Altcoins Breakout Setup: Wedge Since 2018 Could Fuel a 500% “Altcoin Season” Rally
Crypto analyst Cryptollica says the total altcoin market has been compressing inside a large wedge since 2018, including during the prior 2021–2022 altcoin season. He argues the altcoin market bottomed in 2025 and now sits near a potential breakout.
If the wedge breaks, the analyst expects a highly bullish move—over a 500% increase—implying major price upside for majors like ETH and SOL, with broader altcoins making new all-time highs.
To assess timing, the Altcoin Season Index (top 100 altcoins vs BTC) is currently neutral. The index is at 50 (altcoin season typically requires above 75). Bitcoin dominance has fallen below 60% but remains high at 58.8%, which historically is consistent with altcoin season not yet starting.
Key takeaway for traders: the narrative is building for an upcoming altcoin season, but the “when” is not confirmed by BTC-vs-alt relative strength metrics. Watch Bitcoin dominance and the Altcoin Season Index for confirmation of the rotation into altcoins.
Bullish
The article is bullish in tone because it provides a structural setup for the next “altcoin season.” A wedge compression since 2018, a 2025 bottom, and a forecast of 500%+ upside for the total altcoin market are classic ingredients for a later-stage bull-market expansion—similar to how prior altcoin seasons followed periods of long consolidation.
However, it also includes a crucial timing check: the Altcoin Season Index is neutral at 50 and BTC dominance is still high at 58.8%. In past cycles, altcoin rallies typically accelerate only after BTC dominance meaningfully declines and relative performance of top alts vs BTC improves. That suggests this news may drive anticipation and positioning in the short term, but could see choppy price action until the relative-strength indicators flip.
Short-term: traders may buy quality altcoins on “breakout probability” while still watching BTC dominance for confirmation.
Long-term: if the wedge thesis holds, a sustained rotation into ETH/SOL and broader alts could follow, increasing odds of a new multi-year high environment for alt markets.
