Altseason Index Decline: The Altseason Index has dropped from a peak of 100 to 67, indicating a cooling sentiment in the altcoin market and a potential shift back towards Bitcoin dominance.
Bullish TOTAL3 Chart: The TOTAL3 chart, which tracks the crypto market cap excluding Bitcoin and Ethereum, shows a bullish cup-and-handle pattern, suggesting a possible rise in market cap towards $2.1–2.75 trillion if it breaks key resistance levels.
Bitcoin Dominance Breakdown: Bitcoin's market dominance has fallen below 58%, signaling a capital rotation towards altcoins, which aligns with the recent trends in the Altseason Index and TOTAL3 breakout.
Caution in the Market: Despite the signs of altcoin strength, the recent cooling in the Altseason Index suggests that caution is returning to the crypto market.
