According to data collected by Bloomberg Intelligence analyst James Seyffart, the 10 spot bitcoin ETFs (GBTC included) saw a net outflow of $158 million on Wednesday. Day-to-day flows can, of course, be mercurial. Numbers compiled by CoinDesk from the issuers’ websites shows total bitcoin held by all of the spot ETFs (GBTC included) as of Jan. 24 of 642,458 versus 660,540 a week earlier, a decline of more than 18,000 tokens.
