Bitcoin spot ETFs hemorrhaged roughly $64 million in net outflows on June 15, while Ethereum, Solana, and XRP funds collectively pulled in about $28 million.
Ethereum led the altcoin charge with approximately $22.5 million in net inflows. Solana and XRP each attracted around $2.8 million apiece.
Grayscale’s GBTC product continues to be a major contributor to Bitcoin’s outflow problem. The converted trust has been a persistent source of selling pressure since its spot ETF conversion, and the pattern showed no signs of breaking on this particular trading day.
Meanwhile, XRP’s price climbed roughly 7% and Solana gained about 6%. Cumulative inflows for XRP spot ETFs have surpassed $1.44 billion since their launch in late 2025.
The combined $28 million flowing into altcoin ETFs on a single day, while Bitcoin shed $64 million, creates an interesting dynamic. For every dollar going into altcoin ETFs, more than two dollars left Bitcoin funds.
