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.

According to @rovercrc, the Altcoin Season Index has climbed above 75, indicating strong altcoin momentum versus Bitcoin in recent performance data, source: @rovercrc on X (Sep 13, 2025). As defined by Blockchain Center, a reading above 75 means at least 75% of the top 50 altcoins outperformed BTC over the last 90 days, which qualifies as Altcoin Season, source: Blockchain Center Altcoin Season Index methodology. This reading confirms broad-based altcoin outperformance versus BTC over the recent quarter, a condition the index is explicitly designed to identify, source: Blockchain Center Altcoin Season Index.

According to Milk Road, current price action does not qualify as a classic altseason because BTC has moved down while most altcoins remain flat; the real altseason begins when BTC rises and altcoins outperform BTC, driving outsized gains.

According to @rovercrc, BTC has already rallied and ETH is currently rising, and he expects altcoins to move next as the crypto market cycle repeats, source: @rovercrc on X. For confirmation, traders commonly watch a sustained decline in Bitcoin dominance BTC.D and a rising ETHBTC pair, which are associated with phases when altcoins outperform, source: Binance Academy. If BTC dominance continues to rise, altcoins typically lag on a relative basis, source: Binance Academy. Risk management remains critical during rotation attempts, including position sizing and stop losses to control volatility risk, source: Investopedia.

According to @rovercrc, more than $4B has flowed into ETH ETFs this month while BTC ETFs saw $624.48M in outflows, signaling a sharp demand rotation between the two assets (source: @rovercrc on X, Aug 30, 2025). According to @rovercrc, this divergence hints at a potential altseason, implying potential relative-strength upside in ETH/BTC and higher-beta altcoins if the reported flow trend persists (source: @rovercrc on X, Aug 30, 2025). According to @rovercrc, traders can focus on tracking daily net flows of ETH vs BTC ETFs and watch ETH/BTC for breakouts as confirmation before increasing altcoin exposure (source: @rovercrc on X, Aug 30, 2025).

According to @CryptoMichNL, ETH is up 9% in the current move, signaling strong momentum in the Ethereum market cycle.

According to @milesdeutscher, altcoins have broadly outperformed BTC over the last three months, signaling the start of altseason (source: @milesdeutscher on X, Aug 14, 2025). The author shared a ranked list of relative performance versus BTC that traders can use to identify top outperformers and construct a focused watchlist of high relative-strength altcoins (source: @milesdeutscher on X, Aug 14, 2025). To express this theme, prioritize entries on strong BTC pairs from the author’s list and manage risk tightly given the altseason regime identified by the author (source: @milesdeutscher on X, Aug 14, 2025). Confirm the trend by monitoring whether these leaders continue closing weekly candles stronger than BTC, aligning with the author’s altseason call (source: @milesdeutscher on X, Aug 14, 2025).

According to @milesdeutscher, BTC dominance looks extremely weak for the first time since 2024, which the source states has historically triggered altcoin season. According to @milesdeutscher, traders monitoring market rotation can use BTC dominance as a timing gauge for potential altcoin outperformance and volatility shifts.

According to @rovercrc, Ethereum's open interest dominance is now leading the market, indicating a significant shift in trading trends. This suggests that traders are increasingly focusing on ETH derivatives, which historically precedes periods of strong altcoin performance. The source notes that as the market cycle progresses, altcoins are likely to deliver even greater returns, making the current environment particularly favorable for altcoin traders.

According to @rovercrc, ETH is significantly outperforming BTC in Q3 2025, with trading data showing Ethereum's market strength over Bitcoin at this stage of the quarter (source: @rovercrc on Twitter). This trend suggests heightened interest and momentum for ETH traders, indicating potential for continued gains relative to BTC.

According to Cas Abbé, implied volatility on BTC and ETH options is rising, which historically indicates that altcoins may outperform as traders shift to higher beta assets. The increased volatility suggests traders should expect sharp price swings and manage position sizes carefully over the next four weeks (source: Cas Abbé).

According to Michaël van de Poppe (@CryptoMichNL), despite widespread commentary that the 2025 cycle is a Bitcoin-only (BTC) run, historical trends from the 2020 cycle show that altcoins eventually outperformed Bitcoin after similar initial narratives. This suggests that traders holding altcoin portfolios may be positioning for potential outperformance as market rotations develop, a strategy supported by previous cycles (Source: Twitter/@CryptoMichNL).

According to Milk Road (@MilkRoadDaily), the cryptocurrency market was the top performer over the past month, with the total crypto market capitalization growing at a faster pace than Bitcoin itself. This led to a slight decrease in Bitcoin's dominance, indicating that altcoins outpaced BTC in gains. Most notably, crypto nearly doubled the returns compared to major stock indices and gold, highlighting robust investor momentum and risk appetite in digital assets (source: Milk Road Twitter, June 8, 2025). These trends suggest increased capital inflows into the broader crypto market, signaling potential opportunities for traders seeking higher volatility and growth beyond Bitcoin.

According to @AltcoinGordon, 57 of the top 100 altcoins have outperformed Bitcoin (BTC) over the past month as of May 19, 2025 (source: Twitter). This trend highlights growing investor interest in alternative cryptocurrencies and suggests increased capital rotation from BTC into high-performing altcoins. Traders should closely monitor altcoin price action and volume, as continued outperformance may signal a bullish altcoin cycle. Keeping an eye on altcoin market capitalization and BTC dominance metrics can help inform portfolio allocation strategies for maximizing gains in the current environment.

According to Michaël van de Poppe (@CryptoMichNL), Bitcoin is currently testing its price highs and may enter a final consolidation phase before attempting a breakout past its all-time high. During this anticipated consolidation, altcoins are expected to outperform Bitcoin, offering traders potential opportunities for higher short-term returns in the altcoin market. This trend is significant for crypto market participants seeking to rotate capital for maximum gains, as historical patterns indicate that periods of Bitcoin consolidation often coincide with strong altcoin rallies (source: Michaël van de Poppe, Twitter, May 10, 2025).
