On June 15, Bitcoin spot ETFs experienced $64.8 million in outflows, mainly due to Grayscale's GBTC losing $124 million in a single day. However, other Bitcoin funds gained about $59 million, partially offsetting the losses. Meanwhile, altcoin ETFs attracted fresh capital, with Ethereum ETFs gaining $22.5 million, Solana $2.7 million, and XRP $2.8 million. This shift indicates institutional investors are diversifying from Bitcoin into altcoins, with XRP notably accumulating over $1.4 billion since launch, signaling growing confidence in altcoin ETFs as portfolio holdings.
