RSI trends suggest altcoins may repeat previous supercycle patterns.
The Altcoin Season Index has reached a reading of 41, marking its highest level since February 2025. Simultaneously, Bitcoin dominance has declined to 25, the lowest level since March. This shift suggests growing investor interest in altcoins as capital rotates from Bitcoin.
Data from BlockchainCenter.net confirms that altcoin momentum is strengthening. As Bitcoin lags, alternative assets are capturing increased attention from both retail and institutional investors. Consequently, a transition phase appears to be in motion across the broader crypto market.
Market analysts now expect altcoins to outperform in the short term as historical cycles repeat. This aligns with technical data showing consistent breakouts across altcoin market caps.
Analyst el_crypto shared a long-term chart of the TOTAL2 index, which tracks the market cap excluding Bitcoin. The structure mirrors past altcoin cycles from 2015-2017 and 2018-2021, including similar RSI movements. This consistency adds credibility to the idea that altcoins may be entering a fresh expansion phase.
The RSI breakout mirrors past moments that led to explosive rallies in altcoins. These moves followed long consolidation periods, which tend to precede market-wide upward momentum.
Altcoins are also gaining strength as Ethereum’s market cap rises. ETH now ranks among the top 25 global assets by valuation, surpassing major companies like Costco. Such positioning reflects increased legitimacy and mainstream relevance of crypto assets.
Analyst Michaël van de Poppe suggests the gold market may influence crypto short-term. If gold breaks higher, it could place temporary pressure on altcoins. However, he believes the broader altcoin market is in its strongest bull cycle ever.
Moreover, CryptoGoos notes that BTC/ETH is now in a supply zone, while ETH/BTC shows renewed demand. This ratio movement favors Ethereum and supports the broader altcoin narrative. Market rotations typically begin with strength in ETH before spreading to mid- and low-cap assets.
