According to @MilkRoadDaily, altcoins have not broken out against Bitcoin this cycle, with the TOTAL3 index still range-bound instead of delivering its usual once-per-cycle surge that signals peak altseason (Source: @MilkRoadDaily). ETF inflows into BTC and ETH have absorbed liquidity that typically rotates into altcoins, muting TOTAL3 momentum and delaying broad altseason breadth (Source: @MilkRoadDaily). @MilkRoadDaily notes that a decisive TOTAL3 range break historically marks the strongest phase of the bull market, with the expected window in Q4 now underway (Source: @MilkRoadDaily). For trading, @MilkRoadDaily highlights a confirmed TOTAL3 breakout as the key trigger for broad-based altcoin strength and risk-on expansion (Source: @MilkRoadDaily).

According to @rovercrc, altcoins are "breaking out now," flagging a live momentum shift that could open short-term breakout setups in ALTs if confirmed by market-wide strength (source: Crypto Rover on X, Sep 21, 2025). Traders can seek confirmation via 1H closes above recent ranges on the total altcoin market cap index (TOTAL3) alongside rising volume, and by monitoring strength on key relative pairs like ETH/BTC and SOL/BTC for breadth follow-through (source: Crypto Rover on X, Sep 21, 2025). Risk management remains critical: if momentum stalls or BTC dominance (BTC.D) turns higher, altcoin upside can fade, so consider using prior breakout lows as invalidation and trim into nearby resistance (source: Crypto Rover on X, Sep 21, 2025).
