According to Cas Abbé on Twitter, the current altcoin market setup for 2025-26 shows striking similarities to the 2017-18 altseason cycle, with both periods featuring a lack of significant altcoin pumps in Q1 and a comparable macroeconomic context involving a Trump presidency (source: @cas_abbe, May 4, 2025). These parallels suggest traders should monitor historical breakout patterns and rotation flows from Bitcoin to altcoins, as previously seen in the late stages of the 2017-18 cycle. This insight is critical for developing timing strategies and identifying high-probability entry points for leading altcoins as market cycles repeat established behaviors.
