Bitcoin ETFs bled cash Monday while every other crypto ETF gained

US spot bitcoin ETFs lost a net $64 million on Monday, even as spot ETFs for ether, XRP, Solana and Hyperliquid all pulled in fresh cash. On the surface, that looks like a clean rotation out of bitcoin and into everything else.

Ether funds gained $22.5 million, Hyperliquid funds $17.2 million, and the XRP and Solana funds about $2.8 million each. That tracks Monday’s price action, where the alts ran well ahead of bitcoin, with XRP up about 7%, Solana 6% and Hyperliquid 11% on the day. The flows followed the tape.

It is worth keeping the scale in mind. Bitcoin ETFs still hold about $83 billion in assets, against roughly $10 billion for ether and around $1 billion each for the XRP, Solana and Hyperliquid products.

The bitcoin number needs a second look. The outflow was not broad, as BlackRock’s IBIT, the largest fund, actually took in $66 million. The net loss came almost entirely from Grayscale’s GBTC, the high-fee legacy trust that has been shedding assets since these funds launched, which lost $124 million on the day.

The real question is durability. If the altcoin ETFs keep drawing inflows once GBTC’s drag fades, the rotation is real. If not, Monday was a blip dressed up as a trend.
