Shares of major Bitcoin miners like Riot Platforms, MARA Holdings, and CleanSpark fell 5-6% following Strategy's disclosure of selling 1,690 Bitcoin at a loss and 6.59 million common shares to boost cash reserves. This move breaks Strategy's previous 'never sell' stance and adds pressure on the crypto sector amid Bitcoin's ongoing price decline, currently down 27% year-to-date. The CoinShares Valkyrie Bitcoin Miners ETF also dropped 5%, reflecting broader sector weakness. Investors are advised to watch Bitcoin's price stability and any further sales disclosures from Strategy, as sentiment remains fragile in the mining sector.
