According to the source, do not call altseason until two signals appear: Bitcoin (BTC) dominance breaks down and the Others/BTC ratio surges, which are flagged as the confirmation triggers for broader altcoin strength (source: X post on Sep 16, 2025). The post adds that these signals are what a referenced trader watches before rotating into lower-cap altcoins outside ETH and SOL, highlighting a potential market shift once both conditions align (source: X post on Sep 16, 2025).

According to @CryptoMichNL, many altcoins are positioned for a major breakout on higher timeframes, signaling improving momentum for a potential rotation into alts.

According to @rovercrc, ETH is breaking above its previous cycle all-time high and mirrors BTC’s 2020 setup, implying a similar market phase; source: @rovercrc. Traders may watch for confirmation via weekly closes above the prior-ATH zone, retests holding as support, and ETH/BTC strength to gauge potential altcoin rotation; sources: @rovercrc, Investopedia (support and resistance, breakout confirmation), Binance Academy (Bitcoin dominance and altcoin cycles).

According to the source, Bitcoin dominance has been sliding for weeks and a continued downtrend could target 44%, the same level seen at the peak of the 2021 altcoin cycle, signaling potential relative outperformance by alts if reached, source: @MilkRoadDaily. The source states the altcoin market cap excluding BTC and ETH is pressing against its 2021 highs, where a breakout would signal a new expansion phase and the largest rotation of this cycle, source: @MilkRoadDaily. The source reports the Altcoin Season Index is at 78, firmly in altseason territory, source: @MilkRoadDaily. The source highlights a macro headwind with ISM stuck at 48 and in contraction for 30+ months, noting that markets have often turned higher while ISM was below 50 and that gold and the S&P 500 are pushing all-time highs, but the strongest rallies usually begin when ISM returns above 50, source: @MilkRoadDaily. The source adds that tomorrow’s Fed rate decision is pivotal; a cut could help push ISM back above 50, unlock rotations from $7.4T in money market funds into risk assets like crypto, and become the final catalyst for a full-scale altcoin breakout, source: @MilkRoadDaily. For trading, the source suggests watching BTC dominance toward 44%, an altcoin market cap breakout over 2021 highs, Altcoin Season Index sustainability above 75, and the Fed decision as key triggers for rotation into alts, source: @MilkRoadDaily.

According to @rovercrc, the author publicly asked which altcoin could be next to make a large move but did not provide a token name, timeframe, catalyst, or chart, so the post does not constitute an actionable trading signal on its own.

According to @MilkRoadDaily, BTC dominance has been in a 13-week downtrend, reflecting sustained rotation away from Bitcoin (source: @MilkRoadDaily, X, Sep 15, 2025). @MilkRoadDaily reports the current dip in dominance is larger than the decline seen at the end of 2025 (source: @MilkRoadDaily, X, Sep 15, 2025). @MilkRoadDaily adds the Altcoin Season Index is now above 80, indicating broad altcoin outperformance versus BTC pairs (source: @MilkRoadDaily, X, Sep 15, 2025).

According to @rovercrc, the current crypto cycle can be mapped to a 9-phase altseason rotation where strength moves from BTC to ETH, back to BTC, then ETH breaking all-time high, followed by large caps, BTC making a new all-time high, ETH and large caps hitting all-time highs, then mid caps and finally low caps, outlining a sequential allocation roadmap for traders.

According to @MilkRoadDaily, the Altcoin Season Index has reached 84 and was characterized as bullish; source: @MilkRoadDaily on X, Sep 13, 2025. An index reading above 75 qualifies as altcoin season by definition, which assesses whether at least 75% of the top-50 altcoins have outperformed BTC over the last 90 days; source: BlockchainCenter Altcoin Season Index methodology. Traders tracking this signal often monitor alt/BTC pairs and BTC dominance to gauge rotation strength between BTC and altcoins; source: Binance Academy explanation of Bitcoin Dominance as a capital rotation gauge.

According to the source, altseason tends to perform best when the ISM Manufacturing PMI is above 50 and cites an unusually long period of sub-50 readings as context (source: the source). ISM defines PMI values above 50 as expansion and below 50 as contraction and publishes the index monthly on the first business day at 10:00 ET (source: Institute for Supply Management). For trading, monitor the next PMI print alongside crypto breadth indicators such as Bitcoin dominance (BTC.D) and Total3 to confirm rotation into altcoins and adjust beta accordingly (source: TradingView market indices).

According to @rovercrc, the Altcoin Season Index has reached 84, its highest level since last year, signaling strong altcoin outperformance versus BTC (source: @rovercrc on X, Sep 13, 2025). Per Blockchain Center’s methodology, a reading above 75 defines Altseason, meaning at least 75% of the top 50 coins have outperformed BTC over the last 90 days (source: Blockchain Center Altcoin Season Index methodology). Traders typically monitor BTC dominance (BTC.D) and alt/BTC pairs during Altseason as leadership rotates from BTC to altcoins and momentum broadens (source: Binance Academy, What Is Altseason). Such periods historically feature higher volatility and risk, making position sizing and liquidity management more critical for crypto portfolios (source: Binance Academy, What Is Altseason).
