According to @rovercrc, a breakdown in Bitcoin dominance ($BTC.D) is looming, which they claim would trigger a rotation of capital into altcoins. Source: https://twitter.com/rovercrc/status/1965808233831895141 BTC.D tracks Bitcoin’s share of total crypto market capitalization, making it a widely used gauge for potential altseason dynamics when it trends lower. Source: https://www.tradingview.com/symbols/CRYPTOCAP-BTC.D/ Traders commonly confirm rotation by monitoring BTC.D losing key support while CRYPTOCAP:TOTAL2 trends higher and major alt/BTC pairs (e.g., ETHBTC) break up.

According to @rovercrc, BTC.D is hinting a massive altseason, signaling potential rotation from BTC to altcoins, source: X post by @rovercrc on Sep 8, 2025. Traders often view a sustained decline in Bitcoin dominance, the BTC.D chart, as confirmation that altcoins are outperforming, source: TradingView symbol BTC.D. The post did not include chart levels, timeframe, or confirmation metrics, so confirmation would require observing BTC.D trending lower alongside strength in ETHBTC and total altcoin market cap ex BTC and ETH often tracked via TOTAL3, source: X post by @rovercrc on Sep 8, 2025 and TradingView symbols ETHBTC and TOTAL3. If BTC.D instead rises, the altseason thesis weakens and BTC could continue to outperform, source: TradingView symbol BTC.D. Traders can consider waiting for clear BTC.D breakdowns with concurrent higher highs in ETHBTC or TOTAL3 before increasing altcoin exposure, source: TradingView symbols BTC.D, ETHBTC, TOTAL3.

According to @cas_abbe, if the pattern persists into Q4 2025, BTC is expected to break to new highs first, ETH to advance once BTC stabilizes, and altcoins to rotate later with their strongest gains at the end of the liquidity cycle. Source: @cas_abbe. For trading, this sequence favors early focus on BTC breakout setups, a pivot to ETH as BTC volatility compresses, and late-cycle momentum positioning in altcoins.

According to @rovercrc, the Altseason Index is at 59 and he expects a huge altcoin comeback soon, source: Crypto Rover on X dated Sep 5, 2025. An index reading of 59 is below the 75 threshold that defines an Altcoin Season, indicating altcoins have not yet broadly outperformed BTC over the last 90 days, source: BlockchainCenter Altcoin Season Index methodology. For traders, a higher-probability confirmation typically involves the index breaking above 75 alongside declining Bitcoin dominance and a strengthening ETHBTC pair before rotating heavily into altcoins, source: BlockchainCenter and Binance Academy.

According to @ThinkingUSD, ETHBTC is expected to keep trending lower, which implies BTC outperforming ETH on the cross pair. source: @ThinkingUSD on X, Sep 2, 2025; source: Binance Academy, What Are Crypto Trading Pairs For execution, traders can express a bearish ETHBTC view via relative-value positioning using perpetual futures while checking funding rates, order book depth, and fees before entry. source: Binance Academy, Perpetual Futures Funding Rate Explained; source: Hyperliquid documentation, Perpetual Markets and Fees The post explicitly mentions Hyperliquid as the preferred venue but provides no price levels or timeframe, so the signal is directional sentiment rather than a full setup. source: @ThinkingUSD on X, Sep 2, 2025

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 @MilkRoadDaily, Bitcoin dominance (BTC.D) is falling and they frame this as an altseason rotation setup, source: @MilkRoadDaily on X, Aug 31, 2025. They cite March 2021 when BTC.D fell nearly 20% in two months and capital first rotated into ETH, which rose from 1,500 to 4,300 US dollars in 50 days, before moving into other majors like SOL, source: @MilkRoadDaily on X, Aug 31, 2025. The trading takeaway presented is to watch the BTC.D trend and the sequence of capital flow from BTC to ETH and then to large-cap alts such as SOL, as outlined by the source, source: @MilkRoadDaily on X, Aug 31, 2025.

According to Crypto Rover (@rovercrc), a Satoshi-era whale sold 2,000 BTC (about $221M) to buy 49,850 ETH (about $219M), indicating a direct allocation shift from BTC to ETH, source: Crypto Rover (@rovercrc) on X, Aug 30, 2025.

According to Miles Deutscher, in the past two crypto cycles ETH’s most bullish phase occurred after BTC had already peaked for the cycle, pointing to a historical post-peak rotation dynamic favoring ETH; source: Miles Deutscher on X, Aug 28, 2025. He added that altcoins are more reflexive to ETH than to BTC, underscoring ETH’s leadership in driving altcoin beta during cycle transitions; source: Miles Deutscher on X, Aug 28, 2025. For trading, this thesis centers on monitoring a BTC cycle peak as a trigger, then tracking ETH’s relative strength and alt performance as potential follow-through, consistent with the author’s stated pattern; source: Miles Deutscher on X, Aug 28, 2025.

According to @rovercrc, Bitcoin (BTC) looks exhausted while Ethereum (ETH) looks extremely bullish, indicating a straightforward momentum bias in favor of ETH over BTC (source: @rovercrc). According to @rovercrc, traders should avoid overcomplicating the setup and focus on ETH strength versus BTC weakness for near-term positioning (source: @rovercrc).

According to @QCPgroup, BTC dominance slipped from 60% to 57% while still remaining above the sub-50% levels seen in 2021, highlighting a shift in market share that traders track for rotation signals. According to @QCPgroup, the move is fueling speculation that whales expect ETH to outperform, particularly if ETH staking ETFs secure approval later this year.

According to @Excellion, ETHBTC has only been significantly above 0.03 for about seven days, indicating the rally window has been brief and potentially fragile (source: @Excellion). According to @Excellion, traders may need to wait roughly three weeks to sell, highlighting a timing and execution risk that can constrain exits (source: @Excellion). According to @Excellion, this creates a big-door-in, small-door-out dynamic, signaling a liquidity bottleneck that can elevate slippage for ETH/BTC rotations (source: @Excellion).

According to @milesdeutscher, Ethereum’s market cap has historically peaked near 35 percent of Bitcoin’s during major bull runs, with 2017 around 35 percent and 2021 around 36 percent, source: @milesdeutscher citing @YashasEdu.

He notes ETH is still lagging but starting to catch up, highlighting a potential relative strength shift traders can monitor through ETH’s share of BTC market cap, source: @milesdeutscher.

According to @Excellion, there is a notable absence of ETHBTC price predictions from Ethereum analysts, drawing attention to caution around the ETH/BTC cross and public forecasting reluctance.
