According to @CryptoMichNL, the Bitcoin dominance chart (BTC.D) is still tracking the 2019 pattern [source: @CryptoMichNL on X, Jan 1, 2026]. @CryptoMichNL notes there has been no sustained break above the 21-week moving average, and even a temporary break would be consistent with 2019 behavior rather than a reversal of dominance [source: @CryptoMichNL on X, Jan 1, 2026]. @CryptoMichNL states the trend in BTC dominance is down, indicating ETH has taken over leadership versus BTC [source: @CryptoMichNL on X, Jan 1, 2026]. For traders, @CryptoMichNL’s view emphasizes ETH relative strength and the 21-week MA on BTC.D as the key rotation gauge [source: @CryptoMichNL on X, Jan 1, 2026].

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 @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 Michaël van de Poppe (@CryptoMichNL), Bitcoin dominance (BTC.D) remains comparable to the 2019 cycle and has been rejected at the weekly 20-MA, with the next move he expects being a drop, source: @CryptoMichNL on X, Nov 14, 2025. Traders are watching the BTC.D weekly 20-MA rejection as a signal for potential downside follow-through in dominance, per @CryptoMichNL on X, Nov 14, 2025.

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.

According to the source, a weakening in Bitcoin dominance (BTC.D) could indicate the start of an altcoin season, implying potential rotation from BTC into large-cap alts such as ETH, source: X post dated Nov 9, 2025. Traders often seek confirmation via a sustained downtrend in BTC.D below key moving averages and prior swing lows on daily or weekly timeframes, source: TradingView; Investopedia. Concurrent strength in ETH/BTC and an upswing in TOTAL2 (total altcoin market cap) typically reinforce the rotation signal, source: TradingView. Rising positive funding for major altcoin perpetuals alongside neutralizing BTC funding further supports breadth of the move, source: Coinglass. Increased exchange inflows and on-chain activity shifting toward altcoins versus BTC can add confirmation, source: Glassnode.

According to @CryptoMichNL, Bitcoin dominance (BTC.D) remains in an uptrend but is close to breaking lower, mirroring the Q4 2019 setup as posted on Nov 4, 2025; source: @CryptoMichNL. He identifies a drop below the 20-month moving average as the confirmation trigger and notes that if BTC.D loses that level it would be “party time,” signaling a major move; source: @CryptoMichNL. For traders, this frames the 20-month MA on BTC.D as a key level to monitor for positioning decisions; source: @CryptoMichNL.

According to Cas Abbé, Bitcoin never peaks when BTC dominance is at its highest. Source: Cas Abbé on X, Nov 4, 2025.

According to @AltcoinGordon, a Bitcoin dominance crash is coming and altseason has been postponed, not canceled, outlining a rotation thesis between BTC and altcoins shared on X on Nov 2, 2025, source: @AltcoinGordon on X, Nov 2, 2025. For trading, this view suggests caution on altcoins until a confirmed reversal in BTC dominance, with focus on BTC.D, ETHBTC, and TOTAL3 to validate any shift toward altseason, source: Binance Academy, TradingView charts BTC.D, ETHBTC, TOTAL3. The post includes no timeframe or price/level targets, so confirmation may rely on observable signals such as a lower high and breakdown in BTC.D alongside strength in ETHBTC and broad-based gains in TOTAL3 before rotating into alts, source: @AltcoinGordon on X, Nov 2, 2025; TradingView. Rising BTC dominance historically aligns with BTC outperforming altcoins, while falling dominance often precedes altseason, making the BTC.D trend a key risk indicator for allocation decisions, source: Binance Academy.

According to the source, traders asking when altseason starts should track six objective signals that have historically preceded altcoin outperformance, with each tied to verifiable data sources. 1) BTC dominance (BTC.D) rollover: Altseason historically begins when BTC.D tops and enters a downtrend; use breaks below 50D/200D moving averages and lower highs to confirm. Source: Binance Research, Bitcoin dominance studies (2020–2021); TradingView BTC.D index. 2) ETH/BTC trend reversal: Sustained ETH/BTC uptrend (higher highs, closes above the 200D MA) typically leads broader alt strength. Source: Kraken Intelligence, Altcoin season research (2021); Binance Research, factor and beta studies (2021); TradingView ETHBTC. 3) Derivatives rotation: Rising share of open interest and volume in altcoin perpetuals versus BTC, alongside steadily positive alt funding while BTC funding normalizes, has preceded alt rallies. Source: Glassnode Insights, Derivatives and leverage reports (2023); Binance Futures Research, funding and basis (2022); Deribit Insights, perpetual markets notes (2022). 4) Stablecoin dry powder: Increasing aggregate stablecoin supply and rising stablecoin exchange balances, as well as a falling Stablecoin Supply Ratio (SSR), indicate deployable capital into alts. Source: Glassnode, Stablecoin Supply Ratio (SSR) metric documentation (2020); CryptoQuant, stablecoin flow metrics documentation (2021). 5) Market breadth: A majority of top-100 alts closing above their 200D MA with expanding volume signals healthier breadth needed for altseason. Source: TradingView Screener methodology; Binance Research, market breadth and cross-sectional momentum studies (2021). 6) On-chain profit rotation: Elevated realized profits in BTC with a declining short-term holder supply share, followed by increasing alt exchange inflows, suggests rotation risk. Source: Glassnode Insights, realized profit/loss and HODL wave analyses (2021–2023). Trading approach: Wait for at least three of the above triggers to align, then scale into ETH/BTC and a diversified alt/BTC basket; invalidate if BTC.D makes new highs or if ETH/BTC loses its 200D MA on closing basis.
