According to Cas Abbé, the May 2025 Altseason lasted just three weeks, despite significant events such as a US-China trade resolution, increased M2 money supply growth, Bitcoin reaching a new all-time high (ATH), and a peak in BTC dominance. Abbé notes that while these bullish macro and crypto-specific catalysts occurred, the Others/BTC trading pair hit a new cycle low, signaling persistent weakness in altcoins. Abbé emphasizes that until Bitcoin consolidates above its ATH, traders should not expect a sustainable Altseason, highlighting the importance of BTC price action and dominance for altcoin market timing (Source: Cas Abbé on Twitter, May 31, 2025).

According to Milk Road (@MilkRoadDaily) and insights from CarlKVogel, Bitcoin dominance is rising as institutions increasingly use BTC as collateral to build new financial products, potentially signaling the end of the current altcoin season. The discussion highlights a shift in institutional strategy from direct Bitcoin purchases to leveraging BTC for innovative financial infrastructure. Traders should note that increased Bitcoin dominance often results in weaker altcoin performance, and the quiet expansion of Bitcoin-based instruments by institutions could further suppress altcoin rallies in the near term (source: Milk Road Twitter, May 28, 2025).

According to Miles Deutscher, the cryptocurrency market is not yet ready for an 'alt season,' as evidenced by the lack of relative strength in altcoins whenever Bitcoin ($BTC) retraces. Deutscher highlights that this trend is typical during Bitcoin's expansionary phase, suggesting that traders should remain cautious when allocating to altcoins until stronger relative performance is observed. This analysis indicates that Bitcoin dominance remains a central trading focus and that altcoin rallies may be delayed, impacting portfolio strategy and risk management for crypto traders (source: @milesdeutscher, Twitter, May 24, 2025).

According to Mihir (@RhythmicAnalyst), Bitcoin (BTC) dominance is dipping today, which is providing a noticeable boost to altcoins. This shift in market dominance suggests capital rotation from BTC to various altcoins, creating new trading opportunities and increased volatility in the altcoin sector. Traders are advised to monitor leading altcoins for breakout patterns, as the decline in BTC dominance often signals a favorable environment for short-term altcoin gains (source: @RhythmicAnalyst on Twitter, May 22, 2025).

According to Milk Road (@MilkRoadDaily), Bitcoin ($BTC) has recently surpassed its all-time highs (ATHs), drawing significant attention from traders and impacting the altcoin market. As $BTC breaks new records, historical data shows that capital often rotates from Bitcoin to altcoins, leading to increased volatility and potential trading opportunities across alternative cryptocurrencies (source: Milk Road, May 22, 2025). Traders should monitor altcoin price movements closely, as these assets may experience sharp corrections or rallies in reaction to Bitcoin's dominance. The current BTC rally could trigger liquidity flows and affect market sentiment across the broader crypto sector.

According to Adrian (@adriannewman21) on Twitter, several experienced crypto market participants anticipate Bitcoin dominance reaching as high as 80% during the current cycle, effectively equating the broader crypto market with Bitcoin itself (source: Twitter, May 22, 2025). Adrian highlights skepticism towards RWA-linked coins, noting OG perspectives that real world asset (RWA) projects may succeed but their tokens lack strong investment rationale. For traders, this signals a potential continued capital concentration in Bitcoin at the expense of altcoins, increasing the risk of underperformance for non-BTC assets unless altcoins show strong independent momentum. This dominance shift may also impact liquidity and trading volumes across altcoin pairs, particularly those without direct institutional or utility-driven demand.

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 Crypto Rover on Twitter, the market is on the verge of entering Altcoin Season, a period historically marked by significant outperformance of altcoins compared to Bitcoin (source: Crypto Rover, Twitter, May 16, 2025). For traders, this indicates a potential shift in capital flows from Bitcoin into major altcoins, often resulting in increased trading volumes and volatility across assets such as Ethereum, Solana, and Cardano. Monitoring volume spikes and BTC dominance metrics can help identify optimal entry points. The anticipated altcoin rally could influence liquidity, trading strategies, and portfolio allocations in the broader cryptocurrency market.

According to Cas Abbé (@cas_abbe) on Twitter, Bitcoin dominance has peaked after breaking down from its 6-month rising wedge pattern and is now trending lower (source: Twitter, May 16, 2025). This technical breakdown signals a potential shift in market momentum, with a likelihood of a short-term fakeout rally before a larger decline. Historically, such patterns have preceded significant outperformance by altcoins, suggesting traders should monitor altcoin market caps and rotations closely. For crypto traders, this could indicate a favorable environment for altcoin trading strategies, as capital may flow out of BTC and into other digital assets (source: Twitter, May 16, 2025).

According to @BTC_Analysis, Bitcoin dominance is rebounding from a key support level, signaling renewed pressure on altcoins as capital flows favor BTC over alternative cryptocurrencies. Traders should monitor BTC.D charts closely, as historical patterns suggest that rising Bitcoin dominance often coincides with altcoin underperformance and increased volatility in the altcoin sector (source: @BTC_Analysis on Twitter, June 2024). This shift may prompt portfolio rebalancing and risk-off approaches for altcoin-heavy investors.

According to Milk Road (@MilkRoadDaily), Bitcoin dominance may have reached its peak, signaling a potential shift in capital flows from BTC to altcoins (Source: Twitter, May 15, 2025). This development is critical for traders as historical data shows that when BTC dominance tops out, altcoins often experience increased price action and market share. Monitoring BTC dominance charts can help traders identify early signs of an altcoin season and adjust their portfolios accordingly.

According to glassnode, BTC dominance in the crypto market peaked at 64.4% on May 8, 2025, with ETH market share increasing to 9.75% (+3%) and altcoins to 22.35% (+2%) since then, while stablecoins dropped to 6.3%. Despite this shift, both ETH and altcoins remain significantly below their previous dominance peaks of 18% and 28.5% respectively, reinforcing that the current crypto cycle is still driven by Bitcoin. For traders, this continued BTC leadership suggests that altcoin rallies may be limited until a more substantial rotation occurs. Source: glassnode (May 15, 2025)

According to Crypto Rover, BTC dominance is experiencing a significant decline while ETH dominance is rising, signaling the textbook beginning of a massive Utility Season (source: Twitter @rovercrc, May 15, 2025). This shift in market share indicates increased trader interest in Ethereum and other utility-focused altcoins, which historically correlates with stronger performance in DeFi, NFT, and Layer 2 tokens. For crypto traders, monitoring these dominance metrics is essential for identifying early momentum shifts and sector rotations. Such changes can result in increased volatility and trading opportunities across altcoins, as liquidity flows out of Bitcoin and into high-utility assets.

According to QCPgroup, both BTC and ETH initially experienced price dips but have since stabilized at approximately $103K and $2.4K respectively, indicating a period of relative calm in major cryptocurrencies. The notable decline of BTC dominance below the 63% threshold, as reported by QCPgroup, highlights early signs of market rotation, with ETH beginning to outperform BTC. This shift suggests traders are reallocating capital from BTC into ETH and potentially other altcoins, which could fuel increased volatility and new opportunities in the altcoin sector. Monitoring BTC dominance alongside ETH price action may be critical for traders seeking to anticipate momentum shifts in the wider cryptocurrency market. (Source: QCPgroup on Twitter, May 13, 2025)

According to Cas Abbé on Twitter, Ethereum (ETH) must maintain the $2,500 support level to sustain its upward momentum. In March, the $2.5K level served as a major resistance, causing the price to fall to new lows. However, current trading conditions have improved, with two significant bullish catalysts: recent trade deals announced between the US and China, and visible weakness in Bitcoin (BTC) dominance. These factors could support ETH's price stability and potential for gains, as traders monitor the $2.5K level for confirmation of a bullish trend continuation.

According to Mihir (@RhythmicAnalyst) on Twitter, BTC dominance has executed a textbook move by flipping a key resistance level into new support, as detailed in the initial post of his thread (source: @RhythmicAnalyst, May 12, 2025). This technical pattern indicates growing Bitcoin strength relative to altcoins, suggesting potential capital inflow into BTC and possible pressure on altcoin valuations. Traders should monitor BTC dominance charts closely, as this structural shift often precedes major market rotations and impacts crypto portfolio allocation strategies.

According to Mihir (@RhythmicAnalyst) on Twitter, Bitcoin (BTC) dominance has declined for the third consecutive day as of May 10, 2025. This trend is fostering increased trading opportunities for altcoins, as a lower BTC dominance often signals capital rotation into alternative cryptocurrencies. Traders are monitoring this shift closely, as historical patterns suggest that sustained decreases in Bitcoin dominance can trigger altcoin rallies and higher volatility in the broader crypto market (source: @RhythmicAnalyst on Twitter).

According to Milk Road (@MilkRoadDaily), the 2025 altseason has just begun as Bitcoin dominance remains high at 63%. This level of BTC dominance historically indicates that capital may soon rotate into altcoins, potentially leading to significant gains in major altcoin markets such as Ethereum, Solana, and Avalanche. Traders are closely monitoring dominance charts and altcoin volume spikes, as increased altcoin activity often signals the early stages of a broader rally. Source: Milk Road Twitter (May 10, 2025).

According to Cas Abbé on Twitter, BTC plus stablecoin dominance has just reached its multi-cycle resistance level and faced rejection (source: @cas_abbe, May 10, 2025). This technical event signals that while traders often monitor BTC dominance as a cue for altcoin rotation, the combined BTC and stablecoin metric offers deeper insights into capital allocation across the crypto market. A rejection at this resistance suggests limited new capital inflow, raising the potential for increased volatility and sharper moves in altcoins if BTC dominance drops. Active traders should watch this metric closely to anticipate shifts in liquidity and potential altcoin rallies (source: @cas_abbe, May 10, 2025).

According to Crypto Rover, the BTC Dominance (BTC.D) to OTHERS Dominance (OTHERS.D) ratio is moving lower, signaling a shift in market capital from Bitcoin to altcoins (source: Crypto Rover on Twitter, May 10, 2025). This trend often indicates growing strength in the altcoin sector, potentially leading to increased altcoin trading volumes and volatility. Traders should monitor this ratio closely, as a continued decline may present new opportunities for altcoin investments while signaling a possible Bitcoin consolidation phase.
