Altcoin Market Cap Repeats Expansion Pattern Across Identical 91-Day Cycles

• Both 91-day altcoin cycles showed identical market structure and duration, each spanning 13 weekly bars.
• Volume rose from $8.7T to $11.8T between cycles, confirming increased accumulation before breakout.
• The market stayed above a multi-year ascending trendline, signaling consistent structural support through each phase.

The altcoin market has followed a precise 91-day structure in two separate cycles, according to a new analysis. These cycles tracked the total crypto market capitalization excluding Bitcoin and Ethereum (TOTAL3), over a weekly timeframe. In both phases, market structure, volume, and expansion patterns aligned across identical time intervals, suggesting a consistent structural repetition.

Market Follows Fixed 91-Day Cycle With Matching Structure

According to analysis prepared by Sykodelic, the first cycle unfolded over 13 weekly bars, lasting exactly 91 days. During this phase, the market cap transitioned from a flat range into a breakout move. That period saw a cumulative volume of $8.7 trillion. In a mirrored structure, the second cycle followed the same 91-day length and also included 13 bars. 

However, the second period recorded a higher total volume of $11.8 trillion, marking an increase in accumulation activity. Despite similar timeframes, the second cycle delivered stronger upward movement. Expansion was sharper, with price action accelerating more aggressively than in the earlier phase. No retracement patterns were recorded across the final weeks of either cycle.

Multi-Year Support Trendline Remains Intact

An ascending trendline dating back to mid-2022 has acted as support during both accumulation periods. The trendline connects multiple market lows, extending through early 2024. Each correction phase respected this level. No breakdown occurred during consolidation, keeping the upward channel structurally sound.

Throughout both 91-day cycles, the market consistently traded above the trendline. The pattern remained uninterrupted despite temporary pullbacks in volume and price action. The most recent data confirms that the TOTAL3 market cap now exceeds $1.3 trillion. This is among the largest increases recorded outside of Bitcoin and Ethereum since late 2021. The upward candles show vertical movements with limited retracement, echoing the expansion behavior seen in the previous cycle.

Market momentum during the current cycle has matched that of the prior 91-day run. The structure, volume, and timing remain aligned across both cycles. This points to a recurring model rather than isolated movements.

Rising Volume Confirms Increased Accumulation Activity

Between the two cycles, total volume grew from $8.7 trillion to $11.8 trillion. This shows a clear rise in accumulation during the same structural timeframe. Each 91-day period reflected an identical progression in terms of duration, number of bars, and directional momentum.

The upcoming week marks the 92nd day of the second cycle. The structure remains consistent with no deviation from the earlier phase. As of now, the trendline support and identical duration continue to frame the expansion behavior. The current breakout reflects earlier movement patterns based on identical cycle timing, market structure, and volume growth .
