Bitcoin’s recent weakness is being driven by more than ordinary market noise. A security incident tied to Coldcard wallets, uneven spot ETF demand, and a fresh sale from Strategy are combining to pressure sentiment and price at the same time.
What is unsettling the market first
The most urgent issue is the hardware wallet exploit linked to Coldcard. Coinkite has warned that some users may be exposed if their seed phrases were created on specific vulnerable firmware versions, which means the problem is limited to a defined group rather than every device in circulation.
The scale of the incident has grown quickly, and the numbers are hard for traders to ignore:
- Early reports suggested close to $40 million in BTC had been taken from affected wallets.
- Two more attack waves were reported after the initial disclosure.
- Total losses later climbed to 1,367.05 BTC, or about $88.6 million.
- Alex Thorn of Galaxy Digital said he saw a fourth coordinated wave, arguing that the transaction pattern matched vulnerable Coldcard UTXOs.
- Thorn also estimated that roughly 449 BTC could still be exposed and urged affected holders to move funds immediately.
That kind of event does more than remove coins from circulation. It also damages confidence, especially among retail traders who often respond quickly to security scares. According to Santiment, the ratio of positive to negative Bitcoin sentiment across X, Reddit, and Telegram fell to its lowest level since the company began tracking the data, which suggests that fear has become part of the trade.
ETF demand is no longer one-way
Spot Bitcoin ETFs have been one of the strongest institutional access points for the asset, but the flow picture has turned uneven. June was the weakest month on record for the category, while July began with a rebound of nearly $200 million in net inflows during its first week.
That improvement did not hold steadily. The pattern later shifted as follows:
- Inflows slowed in mid-July.
- A stronger stretch then followed, with seven straight days of net inflows from July 14 to July 22.
- After that run ended, outflows returned and erased part of the earlier rebound.
- SoSoValue has not yet released August flow data, so the newest trend remains unconfirmed.
This matters because ETF products are still the preferred route for many cautious investors, including pension funds, hedge funds, and other institutions that want regulated exposure without direct custody. In a period marked by a wallet exploit, that preference can tilt attention toward issuers such as BlackRock, Fidelity, Bitwise, and Franklin Templeton, even if overall demand remains inconsistent.
Strategy is no longer purely accumulating
A third pressure point came from corporate treasury activity. Michael Saylor, co-founder and Executive Chairman of Strategy, said the company raised its USD Reserve by $250 million and completed an $81 million buyback of STRC shares.
The market also noticed a less prominent detail in the same period: Strategy sold 1,637 BTC for roughly $105 million between July 27 and August 2. That reduced its holdings from 843,775 BTC to 842,138 BTC.
The change is small relative to the company’s overall stack, but the signal matters. Strategy built its reputation as one of the most aggressive corporate buyers of Bitcoin, so any net sale, even a modest one, stands out to traders watching for changes in treasury behaviour.
Why the price has stayed under pressure
Seen together, the security breach, the fading ETF bid, and Strategy’s sale provide a clear explanation for Bitcoin’s softer tone. None of these developments alone would necessarily define the market, but in combination they create a more fragile setup.
- Spot price: about $63,600, according to CoinGecko
- Weekly move: roughly down 1%
Seasonality adds another layer. August has often been a difficult month for Bitcoin, finishing lower in 9 of the past 13 years. That history does not guarantee a repeat, but it does matter when the market is already dealing with weaker sentiment, choppy ETF flows, and a high-profile treasury sale. For now, the path of least resistance still looks volatile rather than calm.
