peak for ALTs at around July/August of 2026

That's a long time away, and in previous cycles alts finished around the same time as BTC?

could take another year for ALTs to peak

I doubt it. Last cycle we saw a final wave after 1 year of consolidation (eg XRP big leg up, 1 year sidewas, final wave, we are doing the same as we speak), which went very fast in 1 month and went into top distribution for 6 months, considered a bullish continuation. I expect we are in our final wave in my opinion. BTC dominance only needs 2-3 months to come down to support, and for alts to make their final wave.
