Bitcoin ETFs bled $326.7 million last week while Ethereum and smaller cryptocurrencies pulled in fresh capital. The shift marks a dramatic reversal from early July, when spot Bitcoin products dominated inflows. By month's end, the pattern flipped entirely, with outflows consistently outpacing new money.
BlackRock's IBIT took the biggest hit, shedding $186.3 million in a single week. Bitcoin ETFs saw three days of outflows against just two days of inflows. The picture for Ethereum looked marginally better, with ETH products capturing $27.42 million across the week despite a $32.9 million outflow day. Still, Ethereum also ended underwater on a net basis. BlackRock's ETHA fund, however, pulled $36.6 million inbound.
Smaller coins stealing the show
The real story plays out in the altcoin space. Solana ETFs attracted $2.82 million while XRP products drew $14.85 million. Dogecoin ETFs registered zero flows. Yet the HYPE ETF, tracking smaller-cap cryptocurrencies, captured $14.75 million. More tellingly, when measured against market capitalization, HYPE flows have accelerated far faster than Bitcoin, Ethereum, Solana, or XRP products. Lower absolute dollars into smaller coins translate to outsized percentage gains on their market values, explaining why Bitcoin has struggled to maintain momentum as capital rotates elsewhere.
The altcoin index hit 53, confirming what traders already sense, altcoin season has officially arrived. When smaller cryptocurrencies outperform on an inflow basis relative to their market caps, institutional money is voting with its feet.
Price action versus inflow mechanics
Bitcoin tumbled from roughly $64,000 to $62,556 over the week, a 4% slide. Ethereum and most altcoins followed similar downward paths. For Bitcoin, price weakness fed into ETF outflows, a typical correlation. For altcoins, the dynamic inverted entirely. Ethereum and smaller coins continued attracting inflows even as prices fell, suggesting buyers viewed the dips as entry points rather than sell signals.
The week coincided with the 30-year U.S. Treasury yield climbing to 5.234%, its highest since 2007, before retreating to 5.185%. Rising yields typically pressure risk assets like crypto, yet altcoin ETFs shrugged off the headwind. Michael Saylor from MicroStrategy argued Bitcoin had entered a bottoming phase, though the ETF data tells a different story for now, one where smaller cryptocurrencies hold the upper hand.
