The parallel buying streaks come after a period of heavy institutional accumulation.

BlackRock's iShares Bitcoin Trust (IBIT) supplied $209 million of the $338 million that poured into Bitcoin ETFs on Aug. 24. On the same day, its Ethereum fund ETHA accounted for $90.92 million of the $116 million Ethereum ETF total.

Bitcoin traded near $80,000 on Thursday, up 2.12% over 24 hours. Ether changed hands near $2,480 over the same period.

Total net assets across spot Bitcoin ETFs stood at $79.16 billion. Trading volume across the category reached $8.23 billion, according to CoinGlass data.

The two categories also posted their biggest combined week since October last week, drawing $2.3 billion between them. That run suggests institutions are building positions across both assets rather than rotating between them.

The current streak traces back to Aug. 17, when both categories began a run that reached four days by Aug. 20. It has continued uninterrupted through Aug. 27.

Smaller crypto funds joined the advance. Spot Solana (SOL) ETFs added $60.91 million, and spot Hyperliquid (HYPE) ETFs drew $24.42 million, both on Aug. 27.

Both smaller funds remain far behind Bitcoin and Ether in scale. The same-day gains suggest institutional demand extends beyond the two largest crypto assets.

Sustained ETF demand can matter beyond the daily headline. Steady inflows reduce available supply on spot exchanges, a dynamic that has historically supported price during past accumulation phases.

Nine straight days of buying across both major categories signals broad, not narrow, institutional appetite. Whether that appetite holds into next week may depend on whether Bitcoin and Ether can extend their recent price gains.
