Outflows from US spot Bitcoin exchange-traded funds accelerated sharply on Sept. 10, with total net redemptions reaching $282.7 million, according to data cited by Blockcast from Farside Investors. That marked the third consecutive trading day of net outflows and was more than double the $120.2 million recorded a day earlier. Over the three trading days from Sept. 8 to Sept. 10, cumulative net outflows reached about $449.5 million. ARK Invest and 21Shares’ ARKB posted the largest single-day outflow at $164.3 million. BlackRock’s IBIT also turned negative, recording $24.5 million in net outflows. Other funds, including Fidelity’s FBTC, Bitwise’s BITB, VanEck’s HODL, and Grayscale’s GBTC, also saw money leave, showing that redemptions were no longer limited to one product. The report said Bitcoin was also under pressure during the Sept. 11 Asian trading session, hovering near $77,000 after having recently moved back above $80,000. Blockcast said markets were contending with elevated US Treasury yields, rising energy prices, and a more hawkish outlook for Federal Reserve policy. It added that the latest ETF outflows may reflect a broader risk-off move rather than a shift confined to crypto markets.

Bloomberg ETF analyst Eric Balchunas said on X that GLD and IBIT, which he described as store-of-value assets, have moved back into the 10 most actively traded ETFs. The shift comes after semiconductor ETFs dominated the leaderboard through the summer, with some of those funds now falling in the rankings. Balchunas said the change points again to a debasement trade starting to replace the AI-driven frenzy in market attention and trading activity. He added that semiconductor ETFs are still trading above what their asset size would normally suggest, though that gap is no longer as pronounced as it was earlier. The update highlights a change in ETF trading leadership rather than a full collapse in semiconductor activity, with store-of-value products regaining visibility among the market’s busiest funds.

Bitcoin and Ether exchange-traded funds recorded a combined $1.1 billion in net inflows last week, according to BlockBeats, marking a break from the mostly persistent outflow trend seen through much of 2026. The report said institutional money had started moving back into crypto assets through ETF products. BlackRock’s spot Bitcoin ETF, IBIT, was the dominant source of demand. It accounted for about 80% of total inflows into Bitcoin ETFs during the week, making it the largest single channel for fresh capital entering the segment. Even with the rebound in fund flows, trading activity remained weak. BlockBeats said weekly BTC ETF trading volume fell to its second-lowest level since October 2024, showing that stronger inflows did not translate into a broad pickup in market turnover. The report also noted that both BTC and ETH ETFs had previously faced sustained outflow pressure before the latest reversal in flows.

Bloomberg ETF analyst Eric Balchunas said in a post on X that Robbie Mitchnick stated on a program that Bitcoin holders can now convert BTC into IBIT through an in-kind process with a minimum amount of $1 million. Balchunas added that the previous minimum had been $25 million. The update points to a lower entry threshold for this type of IBIT conversion than before, based on the details shared in his post.

Coldcard users are posting detailed accounts of drained wallets after a firmware flaw made some seeds generated by the hardware wallet guessable, according to TheDefiant. The report says attackers have swept about 1,816 BTC, valued in the article at roughly $114 million, from more than 5,200 addresses in four coordinated waves. Victims say they followed standard self-custody practices: buying from a well-known manufacturer, generating seeds offline, engraving backups into steel, and never entering seed phrases on internet-connected devices. Among the cases cited, Canadian entrepreneur Jonathan Goodman said 18.25 BTC was taken from wallets linked to a Coldcard that had never touched the internet and was stored in a safety deposit box. Other users described racing to recover seed backups while away from home, only to find their balances already at zero. On Reddit and X, posts from affected holders describe losses tied to retirement savings, family wealth plans, and years of bitcoin accumulation. Coldcard maker Coinkite has released patched firmware for all models, paused shipments, and destroyed remaining inventory carrying the affected firmware. CEO Rodolfo Novak, known as NVK, said the team was devastated and urged anyone who generated a seed on a Coldcard to move funds immediately. The open letter did not say whether users whose coins were already stolen would be compensated.
