US spot Bitcoin exchange-traded funds (ETFs) saw their largest-ever single-day outflow on Thursday amid a devastating crypto market bloodbath, with Bitcoin and other major digital coins shedding a chunk of their recent gains as the market continues a correction that began on Wednesday following the FOMC meeting. BTC ETFs Snap 15-Day Positive Flow Streak Roughly $671.9 million exited spot BTC exchange-traded funds on Dec. 19, ending a period of net inflows that started 15 days ago, according to data tracked by Farside Investors. Fidelity’s FBTC led the negative flows, with $208.5 million leaving the fund. Grayscale’s Bitcoin Mini Trust logged $188.6 million in outflows and ARK and 21Shares ARKB recorded $108.4 million in outflows. Grayscale’s Bitcoin Trust (GBTC) and Bitwise’s BITB also posted withdrawals, with GBTC losing $87.9 million and BITB shedding $43.6 million. BlackRock’s IBIT, the biggest spot Bitcoin ETF by assets under management, recorded zero flows yesterday. WisdomTree’s BTCW was the only ETF among the dozen funds to post positive flows, attracting $2 million in investor money. BTC ETF Investment Inflows Coincide With Crypto Sell-Off The spot Bitcoin ETF outflows aligned with a massive sell-off in Bitcoin’s price following a hawkish FOMC where Federal Reserve Chairman Jerome Powell hinted at only a few rate cuts in 2025. Powell then said at a post-FOMC press conference that the central bank wasn’t allowed to own any Bitcoin under current laws — in response to a question about President-elect Donald Trump’s strategic BTC reserve promises. According to CoinGecko , Bitcoin nosedived to a current price of $93,550, just days after rocketing to a new historic peak above $108,000. The benchmark crypto is now down 9% on the day — but other high-cap digital assets are experiencing bigger losses. Ethereum has plummeted by nearly 13% on the day at a current price of $3,217, while the Ripple-promoted XRP has almost matched its crash with a 12.4% dip, changing hands for $2.10 at press time. Meanwhile, the industry’s oldest and largest meme coin Dogecoin (DOGE) is down 22% over the last 24 hours, trading at $0.2838. And Solana’s SOL has collapsed below the psychologically important $200 line, sinking by 12.1% to a current price of $183.23.
