According to @CoinMarketCap, heavy Q2 2025 accumulation propelled a Q3 breakout above the Altseason Index 75 threshold, marking a brief Altcoin Season, source: CoinMarketCap on X, Dec 11, 2025. A tariff-driven liquidity unwind and ETF outflows then triggered a sharp reversal, collapsing the Alt Szn Index to roughly 19 by year-end and flipping conditions back to full Bitcoin Season, source: CoinMarketCap on X, Dec 11, 2025. Traders should tilt exposure toward BTC and monitor ETF net flows and tariff headlines for timing given the reported regime shift, source: CoinMarketCap on X, Dec 11, 2025.

According to the source, roughly $150 billion was added to total crypto market capitalization today. Based on this source-reported surge, traders can seek confirmation via increased spot volumes and sustained bid in BTC and ETH before pressing momentum. With the source-reported inflow, watch BTC dominance versus altcoin breadth to decide between large-cap trend continuation and altcoin beta exposure. If the source-reported aggregate gains lose follow-through into the close, short-term mean-reversion setups in high-beta altcoins may emerge while keeping risk anchored to BTC and ETH liquidity.

According to @CoinMarketCap, BTC dominance has not dipped below 50% in 2025, ended 2024 at 56.7%, and currently stands at 58.8% as of Dec 8, 2025 (source: CoinMarketCap tweet on Dec 8, 2025). Based on CoinMarketCap’s dominance metric, this implies altcoins collectively account for about 41.2% of total crypto market capitalization at present, indicating a larger market share concentration in BTC relative to altcoins for 2025 (source: CoinMarketCap dominance data on Dec 8, 2025).

According to CoinMarketCap, the Altcoin Season Index printed 20 today, indicating the market remains in Bitcoin season (source: CoinMarketCap, Twitter, Nov 28, 2025). By Blockchain Center’s methodology, Altcoin Season requires at least 75% of the top 50 altcoins to outperform BTC over the last 90 days, so a reading of 20 implies BTC has outperformed most large-cap altcoins recently (source: Blockchain Center Altcoin Season Index). Until the index trends materially higher toward 75, momentum positioning favors BTC over broad altcoin baskets due to continued relative strength (source: Blockchain Center Altcoin Season Index). A sustained rise in the index toward 75 would signal increasing rotation risk into altcoins and warrants reassessing allocations (source: Blockchain Center Altcoin Season Index).

According to @CoinMarketCap, BTC dominance slipped while altcoins bounced, with BNB Chain market cap down 6.3% and WLFI up 13% this week, source: @CoinMarketCap on X, Nov 27, 2025. @CoinMarketCap reports small-cap tokens and new infrastructure on BNB Chain continued to show strength as Orbs and THENA shipped new tools, source: @CoinMarketCap on X, Nov 27, 2025. @CoinMarketCap also states that VanEck is eyeing a BNB ETF, source: @CoinMarketCap on X, Nov 27, 2025.

According to @cas_abbe, the Federal Reserve is set to end quantitative tightening next week, and when QT ended in September 2019, BTC fell nearly 65% before recovering with QE while altcoin/BTC pairs rallied about 90%, with many alts down in USD but outperforming in BTC terms (source: @cas_abbe). He adds that most altcoins have been in a bear market since December 2024 and argues that high-confluence alts could outperform BTC on a relative basis if a similar rotation unfolds (source: @cas_abbe). For traders, he implies the focus should be on alt/BTC pairs over USD pairs if QT ends as expected (source: @cas_abbe).

According to @CryptoMichNL, altcoins have broadly underperformed and "completely vanished" versus Bitcoin in recent sessions, indicating a deep altcoin drawdown relative to BTC. According to @CryptoMichNL, Bitcoin (BTC) fell roughly 20–25% while the ETH/BTC pair stayed flat over the past two weeks, signaling relative strength for Ethereum (ETH) against Bitcoin. According to @CryptoMichNL, he expects altcoins to rebound more strongly than BTC once BTC finds a low and consolidates, making ETH/BTC a key rotation gauge to watch.

According to @BullTheoryio, BTC is down 24.15% in November while the ALT/BTC ratio is up 9.44%, a rare divergence that signals altcoin seller exhaustion based on their chart analysis. According to @BullTheoryio, daily RSI is the lowest in 2 years, weekly RSI is back to January 2023 levels, and daily MACD has hit its lowest reading on record, readings the author says typically mark local bottoms. According to @BullTheoryio, when BTC transitions to sideways or a slow reversal, altcoins historically outperform in both BTC and USD pairs as positioning resets, leverage is cleared, and seller pressure fades. According to @BullTheoryio, traders should watch ALT/BTC breaking up from its base, BTC approaching major support with deeply oversold indicators, and BTC dominance struggling to rise during the dump as signals that liquidity is rotating toward higher-beta assets.

According to @CryptoMichNL, BTC dominance has broken down, and if this weakness continues over the coming weeks it would not signal a bear market in his view (source: X post by Michaël van de Poppe, Nov 20, 2025). For trading, BTC.D tracks Bitcoin’s share of total crypto market capitalization and is widely monitored to assess rotations between BTC and altcoins (source: TradingView BTC.D index). Traders can focus on confirmation of follow-through in BTC.D and adjust BTC versus altcoin exposure only after confirmation aligns with the stated view of ongoing weakness (source: X post by Michaël van de Poppe, Nov 20, 2025; source: TradingView BTC.D index).

According to @MI_Algos, the latest BTC drawdown reflects a leverage flush and weak-hand capitulation across BTC, ETH and altcoins rather than a confirmed structural breakdown, highlighted by mass liquidations and extreme fear readings, which have historically presented opportunity zones for disciplined traders, source: @MI_Algos. According to @MI_Algos, a 50-day and 200-day SMA death cross is imminent and has historically aligned with macro bottoms in BTC, with the path hinging on whether price can hold support within the larger structure, source: @MI_Algos. According to @MI_Algos, the critical pivot is the Yearly Open near 93.3k, where weekly and monthly closes below that level would open risks for a 50 to 60 percent drawdown, while holding and reclaiming the 50-day SMA into the weekly close would favor stabilization, source: @MI_Algos. According to @MI_Algos citing Chainalysis, North America processed 2.3 trillion dollars in crypto transactions from July 2024 to June 2025 with 45 percent in transfers over 10 million dollars, indicating elevated institutional participation, source: Chainalysis via @MI_Algos. According to @MI_Algos citing industry observations, large institutions are building custody and settlement rails, consistent with ongoing enterprise adoption trends, source: EY via @MI_Algos. According to @MI_Algos, traders should monitor BTC dominance versus TOTAL3 for rotation signals, USDT dominance for risk-on or risk-off, and whether BTC can recapture the 50-day SMA to neutralize the immediate death-cross risk and set up a later golden cross, source: @MI_Algos. According to @MI_Algos, the author’s scenarios are worst case a breakdown below the Yearly Open into a 50 to 60 percent bear market, base case fear and greed at 8 to 11 with consolidation above the Yearly Open and recovery toward price discovery in 2026, and best case a quiet institutional bid that averts major downside, source: @MI_Algos. According to @MI_Algos, the actionable approach is range trading with predefined levels, watching liquidity and dominance flows, and letting the chart data, not narratives, drive execution, source: @MI_Algos.

According to @ReetikaTrades, current Crypto Twitter warnings that the cycle might be over are late because many altcoins are already effectively at zero, underscoring heavy drawdowns in smaller coins (source: @ReetikaTrades on X, Nov 13, 2025). According to @ReetikaTrades, these warnings are not about Bitcoin and she implies few commentators actually own BTC, reinforcing a BTC-over-altcoins bias in positioning and sentiment (source: @ReetikaTrades on X, Nov 13, 2025). For traders applying this view, risk concentration appears highest in illiquid altcoins while BTC may serve as the relative-strength benchmark to prioritize for allocation and risk management (source: @ReetikaTrades on X, Nov 13, 2025).

According to the source, Cathie Wood said stablecoins are replacing the payments role that BTC was expected to fulfill in emerging markets, while Bitcoin’s store-of-value function should have surged. According to the source, this view shifts trading focus toward the digital-gold narrative, suggesting attention to BTC dominance and spot accumulation strategies over payments adoption trades. According to the source, traders should monitor BTC dominance, overall stablecoin supply growth, and on-chain demand indicators to gauge whether the store-of-value narrative strengthens BTC on dips.

According to Miles Deutscher, he has shared a Bitcoin dominance (BTC.D) analysis outlining what needs to happen for altcoins to pump, directing traders’ attention to dominance-driven rotation dynamics. Source: Miles Deutscher on X, Nov 9, 2025. Bitcoin dominance measures BTC’s share of total crypto market value, so a sustained decline in BTC.D mathematically signals capital rotating into non-BTC assets, a key precondition for broad altcoin outperformance. Source: CoinMarketCap Glossary on Bitcoin Dominance. Traders commonly track BTC.D on TradingView and look for lower highs or breakdowns to confirm rotation, as falling dominance historically aligns with stronger altcoin breadth. Source: TradingView BTC.D index. A practical confirmation is BTC.D trending down while the total crypto market cap ex-BTC (TOTAL2) trends up, indicating net inflows to altcoins rather than isolated spikes. Source: TradingView TOTAL2 and BTC.D. When BTC price action stabilizes while BTC.D falls, altcoins typically see relative strength; conversely, rising BTC.D often suppresses altcoin performance as BTC absorbs a larger share of flows.

According to @CryptoMichNL, the market setup resembles Q4 2019–Q1 2020, noting that altcoins lagged before rotating then, and that BTC dominance has made its first pullback with a second decline expected this quarter, implying a possible altcoin outperformance if confirmed (source: @CryptoMichNL on X, Nov 9, 2025). For trading, this view suggests monitoring BTC.D for a second leg lower and tracking alt/BTC pairs for strength and liquidity rotation around that signal (source: @CryptoMichNL on X, Nov 9, 2025).

According to the source, a decline in Bitcoin dominance (BTC.D) is being flagged as a potential early signal for an altcoin season rotation. Source: public X post dated Nov 9, 2025. Historically, sharp drops in BTC.D preceded broad altcoin outperformance in 2017 and early 2021, when BTC.D fell from roughly 85% to 38% (2017) and from about 72% to 40% (2021). Source: CoinMarketCap historical dominance data; TradingView BTC.D.

According to the source, the hypothetical disappearance of Bitcoin focuses traders on liquidity concentration and cross-asset correlations, with BTC representing roughly half of total crypto market capitalization across 2023–2024, implying a large-cap and liquidity shock if removed, source: CoinMarketCap Bitcoin Dominance data. ETH has maintained a strong positive 90-day rolling correlation with BTC, frequently above 0.6 in 2023–2024, indicating ETHUSD and ETHBTC dislocations and higher basis volatility when BTC experiences regime shifts, source: Kaiko correlations research. On centralized exchanges, BTC provides the deepest order books and a large share of spot and derivatives activity, and episodes of BTC-led stress have coincided with wider spreads and thinner depth in altcoin books, implying immediate liquidity deterioration if BTC were removed, source: Kaiko Market Structure reports and CCData Exchange Review 2024.

Stablecoins such as USDT and USDC are the dominant quote assets for altcoins, so trading would likely reroute to stablecoin pairs, but historical structural shifts have shown initial liquidity fragmentation and higher slippage, source: Kaiko stablecoin market share analyses and Binance Research liquidity studies.
