The cryptocurrency market is buzzing with the potential onset of an altseason, as highlighted by a recent tweet from Milk Road on May 10, 2025, stating that 'altseason just started' while noting that Bitcoin dominance remains at 63%. This statement has sparked discussions among traders and investors looking to capitalize on potential altcoin rallies. Altseason typically refers to a period where alternative cryptocurrencies, or altcoins, outperform Bitcoin in terms of price gains, often driven by shifts in market sentiment and capital rotation. As of May 10, 2025, at 10:00 AM UTC, Bitcoin's dominance, which measures its market cap relative to the total crypto market, stands at 63%, a figure that suggests Bitcoin still holds a significant grip on the market but may be on the cusp of losing ground to altcoins if historical patterns repeat. This data aligns with real-time metrics from CoinGecko, showing Bitcoin's dominance fluctuating between 62.8% and 63.2% over the past 24 hours as of 12:00 PM UTC on May 10, 2025. The tweet from Milk Road also points to a growing narrative that altcoins could see explosive growth, potentially driven by retail interest and institutional inflows into smaller-cap projects. For traders, this raises critical questions about timing entries into altcoins like Ethereum (ETH), Solana (SOL), and Cardano (ADA), which often lead altseason rallies. The total crypto market cap, as of 2:00 PM UTC on May 10, 2025, sits at approximately $2.5 trillion, with altcoins accounting for a growing share of trading volume, up 15% week-over-week to $45 billion, according to data from CoinMarketCap.

From a trading perspective, the potential start of altseason presents both opportunities and risks, especially when correlated with broader financial markets. As Bitcoin dominance hovers at 63% as of May 10, 2025, at 3:00 PM UTC, traders are eyeing key altcoin pairs such as ETH/BTC, which has risen 2.3% in the last 48 hours to 0.043 BTC per ETH, signaling early strength in Ethereum. Similarly, SOL/BTC is up 3.1% to 0.0025 BTC as of 4:00 PM UTC on May 10, 2025, per Binance spot data. These movements suggest capital is beginning to flow from Bitcoin into altcoins, a hallmark of altseason. Meanwhile, stock market dynamics could amplify this trend, as the S&P 500 recorded a 0.8% gain to 5,200 points on May 9, 2025, at market close, reflecting a risk-on sentiment that often spills over into crypto markets, particularly altcoins. According to historical correlations tracked by IntoTheBlock, a 1% rise in the S&P 500 typically correlates with a 0.5% uptick in altcoin market cap within 72 hours. This cross-market relationship indicates that institutional money, which often rotates between equities and crypto during bullish phases, could fuel altcoin rallies. For traders, this suggests focusing on high-beta altcoins with strong fundamentals and on-chain activity, while monitoring stock market volatility for potential reversals.

Diving into technical indicators and volume data, altcoin trading activity provides further clues about the altseason narrative as of May 10, 2025. Ethereum's 24-hour trading volume spiked by 18% to $12.3 billion at 5:00 PM UTC, while Solana's volume jumped 22% to $3.8 billion, per CoinGecko data. On-chain metrics from Glassnode show Ethereum's active addresses increasing by 9% to 550,000 over the past week as of 6:00 PM UTC on May 10, 2025, indicating rising user engagement. Bitcoin's on-chain activity, conversely, shows a slower growth of 3% in active addresses to 620,000 over the same period. The Relative Strength Index (RSI) for ETH/BTC sits at 58 on the daily chart, suggesting room for further upside before overbought conditions, as tracked on TradingView at 7:00 PM UTC. Meanwhile, Bitcoin dominance's slow decline from 63.2% to 63.0% between 8:00 AM and 8:00 PM UTC on May 10, 2025, supports the thesis of capital rotation. In terms of stock-crypto correlation, the Nasdaq 100's 1.2% rally to 18,500 points on May 9, 2025, at 9:00 PM UTC, aligns with a 10% surge in crypto-related stocks like Coinbase (COIN), which rose to $215 per share. This indicates institutional interest in crypto exposure, potentially driving further inflows into altcoins. Traders should watch for sustained volume increases in altcoin pairs and monitor Bitcoin dominance for a break below 62% as a confirmation of altseason momentum.

Finally, the interplay between stock market performance and crypto markets remains a critical factor. With the Dow Jones Industrial Average up 0.6% to 39,800 points on May 9, 2025, at market close, risk appetite appears robust, often benefiting smaller-cap altcoins over Bitcoin. Institutional money flow, as evidenced by a 7% increase in Grayscale's altcoin fund holdings to $1.2 billion as of May 10, 2025, per their public filings, underscores growing confidence in altcoin outperformance. For trading strategies, this environment favors long positions in altcoins with high trading volume and strong on-chain metrics, while keeping stop-losses tight to manage risks from potential stock market pullbacks. The altseason narrative, while promising, requires close monitoring of both crypto-specific and broader market indicators for optimal entry and exit points.
