BlackRock's iShares Bitcoin Trust (IBIT) registered no new inflows on Monday, while U.S. Bitcoin (BTC) spot ETFs collectively lost $263 million that day. The downturn ended a nine-day streak of inflows.

The turning point came at a tense time for the largest spot Bitcoin product. IBIT's flows have been largely unchanged for six months. Interested investors seem to have lost their appetite, even though BTC trades close to recent highs.

The nine-day Bitcoin ETF streak ends.

Data from SoSoValue shows that U.S. Bitcoin spot ETFs collectively lost $263 million on April 27. This broke a nine-session streak of inflows. The funds had collectively gained about $767 million the week before.

BlackRock's IBIT dodged the drive sell-off. But the fund's net flow has been flat for about six months. This standstill occurs while Bitcoin continues to trade below the psychological level of $80,000.

U.S. Ethereum (ETH) spot ETFs lost $50.48 million on the same day. Almost all funds in the category reported outflows.

BlackRock's Staked ETH ETF, with ticker ETHB, was the only product in the group that attracted new investments. This distribution suggests that investors may prefer staked exposure over passive holdings as Ethereum's yield rises.

Solana (SOL) ETFs also saw a slight drop with a net sell of $1.21 million, despite a strong weekly performance. Meanwhile, the seven-day window for BTC ETFs remains positive with $283 million.

For BlackRock, the contrast between IBIT's inactivity and ETHB's lone inflow indicates where institutional risk appetite is heading.

Investors apparently prefer yield-bearing products over passive Bitcoin exposure as the second quarter nears its end.
