According to @rovercrc, altcoins just wicked to their lowest levels against BTC since the 2021 COVID crash, source: @rovercrc. According to @rovercrc, that 2021 setup was followed by a massive altseason, which market participants may view as a rotational precedent rather than a guarantee, source: @rovercrc. According to @rovercrc, the trading takeaway is that extreme lows on ALT/BTC pairs have historically preceded altcoin outperformance phases, prompting close monitoring of the ALT/BTC ratio for potential rotation signals, source: @rovercrc.

According to @rovercrc, the Altcoin Season Index stands at 59 on August 31, 2025, highlighting current market positioning relative to BTC, source: @rovercrc. Per BlockchainCenter’s methodology, Altcoin Season is defined when 75% of the top 50 coins outperform BTC over the last 90 days, implying an index reading of 75 or higher, source: BlockchainCenter. A reading of 59 is below that threshold and therefore does not meet the site’s Altseason definition, source: BlockchainCenter. The author frames this level as a discounted entry window for altcoins, which is an opinion rather than a confirmed signal, source: @rovercrc.
