On June 4, 2025, the cryptocurrency market witnessed significant institutional activity as Bitcoin and Ethereum ETFs recorded substantial inflows, signaling strong investor confidence in digital assets. According to data shared by Lookonchain, a well-known on-chain analytics platform, 10 Bitcoin ETFs reported a net inflow of 3,302 BTC, equivalent to approximately $345.62 million, as of the close of trading on June 4 at 16:00 UTC. Notably, ARK21Shares led the pack with an inflow of 1,317 BTC, valued at $137.84 million, bringing its total holdings to 46,614 BTC, or roughly $4.88 billion at current market prices. Simultaneously, 9 Ethereum ETFs saw a net inflow of 38,478 ETH, worth about $100.43 million, with BlackRock’s iShares ETF accounting for the lion’s share at 29,360 ETH, or $76.63 million, as of the same timestamp. This surge in ETF inflows coincides with a broader stock market rally, particularly in tech-heavy indices like the NASDAQ, which gained 1.2% on June 4 by 16:00 UTC, driven by optimism around inflation cooling and potential Federal Reserve rate cuts. The correlation between traditional markets and crypto assets is evident, as institutional investors appear to be rotating capital into risk-on assets like Bitcoin and Ethereum. This cross-market dynamic highlights how stock market sentiment can directly influence crypto inflows, especially through regulated investment vehicles like ETFs. For traders, this event underscores a growing trend of institutional adoption, potentially setting the stage for sustained bullish momentum in both BTC and ETH markets over the coming weeks.

From a trading perspective, the ETF inflows reported on June 4, 2025, present actionable opportunities for crypto investors. The $345.62 million inflow into Bitcoin ETFs suggests a strong demand for exposure to BTC, which could drive spot prices higher in the short term. On June 4 at 16:00 UTC, Bitcoin was trading at approximately $104,700 per coin, based on the inflow valuation, while Ethereum traded near $2,610 per coin. These inflows, particularly BlackRock’s dominant $76.63 million allocation to ETH, indicate that institutional money is favoring Ethereum as a diversification play alongside Bitcoin. For traders, key pairs to watch include BTC/USD, ETH/USD, and BTC/ETH, as relative strength between the two assets may shift based on ETF-driven volume. Additionally, the stock market’s positive performance on June 4, with the S&P 500 up 0.8% by 16:00 UTC, suggests a risk-on environment that often benefits cryptocurrencies. This correlation implies that any continued strength in equities could spill over into crypto markets, creating buying opportunities. However, traders should remain cautious of potential reversals if stock market gains falter, as profit-taking in equities often leads to sell-offs in high-risk assets like crypto. Monitoring institutional flows via ETF data will be critical for gauging momentum, especially as these inflows reflect sustained capital allocation rather than speculative retail buying.

Delving into technical indicators and volume data, Bitcoin’s trading volume spiked by 18% on June 4, 2025, reaching $42 billion across major exchanges by 16:00 UTC, reflecting heightened activity post-ETF inflow news, as reported by on-chain analytics sources. Ethereum saw a similar uptick, with a 15% increase in volume to $18 billion during the same period. On the charts, BTC/USD tested resistance at $105,000 on June 4 at 14:00 UTC, with the Relative Strength Index (RSI) hovering near 68, indicating bullish momentum but approaching overbought territory. ETH/USD showed strength around $2,620, with a key support level at $2,550 holding firm as of 15:00 UTC. Cross-market correlation remains strong, as Bitcoin’s price movements mirrored the NASDAQ’s intraday gains, with a correlation coefficient of 0.85 observed over the past week. Institutional money flow into crypto-related stocks, such as MicroStrategy (MSTR), also saw a 3.5% uptick on June 4 by 16:00 UTC, reflecting parallel interest in crypto exposure via equities. For traders, these metrics suggest a potential breakout if ETF inflows continue, but volume confirmation will be key. The risk appetite in traditional markets, bolstered by ETF-driven capital, points to a favorable environment for long positions in BTC and ETH, provided stock market stability persists.

In terms of stock-crypto market correlation, the June 4, 2025, data underscores how institutional investors are increasingly viewing cryptocurrencies as part of a broader risk-on portfolio. The inflows into Bitcoin and Ethereum ETFs align with gains in tech stocks, suggesting that capital is flowing freely between asset classes. This dynamic creates opportunities for traders to capitalize on correlated movements, such as pairing BTC longs with tech stock ETFs like QQQ. However, the risk of sudden shifts in sentiment remains, as any negative stock market news could trigger outflows from both equities and crypto. Overall, the institutional adoption signaled by these ETF inflows highlights a maturing crypto market, with significant implications for long-term trading strategies.
