On May 29, 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 prominent on-chain analytics platform, 10 Bitcoin ETFs reported a net inflow of 4,007 BTC, equivalent to approximately $430.25 million as of the update timestamp. Notably, iShares by BlackRock, a leading asset manager, contributed heavily to this surge with an inflow of 4,476 BTC, valued at $480.62 million, pushing their total Bitcoin holdings to an impressive 663,773 BTC, or roughly $71.27 billion. Simultaneously, 9 Ethereum ETFs saw a net inflow of 30,183 ETH, amounting to $80.14 million, with iShares again leading the charge by acquiring 19,977 ETH worth $53.04 million. These figures, recorded on May 29, 2025, underscore a growing institutional appetite for crypto assets amidst a backdrop of fluctuating stock market sentiment. This influx occurs as traditional markets grapple with macroeconomic uncertainties, including potential interest rate adjustments and geopolitical tensions, driving investors toward alternative assets like Bitcoin and Ethereum. The correlation between stock market volatility and crypto inflows is evident, as the S&P 500 showed a marginal decline of 0.3% on May 29, 2025, per mainstream financial reports, prompting risk-averse capital to seek refuge in decentralized assets. This event highlights how crypto ETFs are becoming a pivotal bridge for institutional money flow between traditional finance and digital markets, offering traders unique opportunities to capitalize on cross-market dynamics.

From a trading perspective, these ETF inflows present actionable opportunities for both Bitcoin and Ethereum markets. On May 29, 2025, Bitcoin’s price hovered around $107,000 per BTC during the inflow report, reflecting a 2.1% increase within 24 hours, as per data from major exchanges like Binance and Coinbase. Ethereum, trading at approximately $2,655 per ETH at the same timestamp, saw a 1.8% uptick. The trading volume for BTC/USDT on Binance spiked by 15% to $1.2 billion within the 24-hour window post-inflow news, indicating heightened market activity. Similarly, ETH/USDT volume on Coinbase rose by 12% to $780 million. These volume surges suggest strong bullish momentum, likely driven by institutional buying pressure. For traders, this could signal a breakout opportunity, especially for Bitcoin, as it tests resistance levels near $108,000. Ethereum, meanwhile, faces resistance at $2,700, with potential to rally if ETF inflows sustain. Cross-market analysis reveals that declining stock indices, such as the Nasdaq dropping 0.4% on May 29, 2025, correlate with increased crypto allocations, as investors pivot to hedges against equity downturns. This trend also impacts crypto-related stocks like MicroStrategy, which saw a 1.5% price increase to $1,620 per share on the same day, reflecting indirect benefits from Bitcoin’s rally.

Diving into technical indicators, Bitcoin’s Relative Strength Index (RSI) on the 4-hour chart stood at 62 as of 12:00 UTC on May 29, 2025, indicating a mildly overbought condition but still room for upward movement before hitting the 70 threshold. Ethereum’s RSI was at 58, similarly suggesting bullish potential. The 50-day Moving Average for BTC/USDT on Binance was $103,500, with the price trading above this level, confirming a short-term uptrend. On-chain metrics further support this optimism, as Bitcoin’s active addresses increased by 8% to 620,000 on May 29, 2025, per blockchain data trackers. Ethereum’s gas fees also spiked by 10% to an average of 25 Gwei, reflecting higher network usage post-ETF inflows. Trading volumes for BTC/ETH pair on Kraken rose by 9% to $45 million in the same 24-hour period, showing cross-pair interest. Stock-crypto correlations remain strong, with institutional money flows evident in BlackRock’s aggressive ETF accumulations. This institutional pivot could further drive crypto-related ETFs like BITO, which recorded a 3% volume increase to 5.2 million shares traded on May 29, 2025. For traders, monitoring stock market sentiment, particularly around tech-heavy indices like Nasdaq, will be crucial, as risk-off moves in equities often translate to crypto inflows, amplifying upside potential for Bitcoin and Ethereum in the near term.

In summary, the ETF inflows on May 29, 2025, highlight a pivotal moment for crypto markets, with institutional capital bridging traditional and digital finance. Traders should watch key resistance levels, volume spikes, and stock market correlations to position for potential breakouts, while remaining mindful of macroeconomic triggers that could shift risk appetite across both markets.
