Security concerns are hitting confidence first
Bitcoin’s recent weakness is being driven by more than ordinary profit-taking. A hardware-wallet issue tied to Coldcard has become the clearest source of stress, because the warning from manufacturer Coinkite applies to users who generated seed phrases on specific vulnerable firmware builds rather than to every device in circulation. That distinction matters, but the market has still treated the disclosure as a broad warning sign.
The incident has escalated quickly. Initial estimates pointed to almost $40 million in bitcoin being removed from affected addresses, then two more attack waves followed. The latest tally puts cumulative losses at 1,367.05 BTC, or roughly $88.6 million. Alex Thorn, head of firmwide research at Galaxy Digital, later identified a fourth coordinated wave and said the transaction pattern matched vulnerable Coldcard UTXOs, giving him high confidence that another round of theft was underway. He also said affected holders should move funds immediately, with about 449 BTC still exposed in that wave.
The damage is not just financial. Santiment reported that Bitcoin’s positive-to-negative sentiment ratio across X, Reddit, and Telegram fell to its lowest level since the firm began tracking that data. That kind of sentiment break often matters because it shows retail enthusiasm fading at the same time as price pressure builds.
ETF demand improved, then lost momentum again
Spot Bitcoin ETFs have offered a mixed signal. June was the weakest month on record for the category, but July began with a strong recovery, including nearly $200 million in net inflows during the first week. That suggested institutional buyers were returning after a soft stretch.
The rebound did not hold in a straight line. Inflows slowed by mid-month, then improved again during a seven-day stretch from July 14 to July 22, which was the longest run of net inflows since April. Since that streak ended, however, outflows have returned and have erased much of the mid-month strength. SoSoValue has not yet released August flow data, so the current direction remains unconfirmed.
This matters because spot ETFs are the main route for cautious institutional money. Pension funds, hedge funds, and other regulated allocators often prefer that structure because it avoids the complexity of direct custody. With the Coldcard issue still unfolding, the appeal of products from BlackRock, Fidelity, Bitwise, and Franklin Templeton may stay elevated for that investor base.
Strategy’s sale added more pressure
A third weight came from corporate treasury activity. Strategy, led by co-founder and Executive Chairman Michael Saylor, said it increased its USD Reserve by $250 million and completed an $81 million buyback of STRC shares. Buried in the same disclosure was a sale of 1,637 BTC for about $105 million between July 27 and August 2.
That move trimmed Strategy’s holdings from 843,775 BTC to 842,138 BTC. The change is small in percentage terms, but it still stands out because the company has long been viewed as a persistent accumulator rather than a seller. Even limited distribution from a major corporate holder can affect market tone when sentiment is already fragile.
- The security scare weakened confidence and pushed social sentiment lower.
- ETF flows improved briefly, then slipped back into net outflows.
- Strategy’s sale reinforced the idea that large buyers are not absorbing supply as quickly as before.
Bitcoin was trading near $63,600 according to CoinGecko, with the weekly move sitting at roughly 1% lower. Seasonal history also deserves attention: August has ended lower in 9 of the past 13 years, which does not guarantee another weak month, but it does add context to the current setup. With a security shock, softer ETF demand, and corporate selling all landing at once, near-term volatility remains the most important risk to watch.
