Bitcoin Mining ETF WGMI down 43%, worst performer of 2025

CoinShares' Valkyrie Bitcoin Mining ETF (WGMI) is the worst-performing ETF of 2025, down 43% year-to-date, largely due to steep losses in top holdings like IREN, Core Scientific and Cipher Mining, according to CoinDesk. Rising Bitcoin network difficulty and low transaction fees have squeezed miner profits, while WGMI lags behind strong-performing metals ETFs, especially those focused on gold.
