Bitcoin News Today: Altcoin Season Index Rises to 51 as Bitcoin Dominance Dips to 61%

Changpeng “CZ” Zhao, founder of Binance, has signaled growing optimism in the cryptocurrency market, noting that CoinMarketCap’s Altcoin Season Index is rising. In a post on X, Zhao wrote, “Not sure how accurate it is, but it is ticking up. FOMO season soon…” [1], referencing the index that measures whether altcoins are outperforming Bitcoin over a 90-day period. The index currently stands at 51 out of 100, up from 38 last week and 16 a month ago, reflecting a shift in market dynamics [2]. A reading above 75 is considered an official “Altcoin Season,” where at least 75 of the top 100 altcoins outperform Bitcoin [3].

The index’s upward trajectory aligns with broader market trends. Bitcoin’s dominance has dropped to 61%, its lowest since March and the sharpest decline since June 2022, according to TradingView [4]. This decline coincides with a 23% surge in total crypto market capitalization over three weeks, reaching $3.8 trillion [5]. Ethereum and meme coins like BONK and FLOKI have led altcoin gains, with Ethereum up 110% over 90 days and BONK surging 148.7% [6]. Lower-cap projects such as PENGU and M have also seen over 500% gains [7].

Historical patterns suggest a typical market cycle: Bitcoin initially drives liquidity and sentiment, followed by a shift to altcoins fueled by speculative narratives and protocol innovation [8]. For example, in 2021, altcoins posted 170% gains while Bitcoin rose just 2% during the same period [9]. However, some analysts remain cautious. X user Henry noted that while retail investors are declaring an altcoin rally, key metrics like Bitcoin dominance (61%) and the Altcoin Season Index (51) have yet to meet traditional bull market indicators [10].

The Altcoin Season Index’s methodology excludes stablecoins and wrapped tokens, focusing instead on price performance among the top 100 coins on CoinMarketCap [11]. This metric aims to help investors assess whether the market is transitioning from Bitcoin-led growth to broader altcoin participation. Zhao’s commentary adds to a growing narrative of market rotation, though traders are advised to monitor Bitcoin’s dominance and technical indicators for confirmation of a sustained altcoin-driven phase [12].
