Bitcoin’s latest slide is being driven by a tight cluster of negative forces: a hardware wallet security problem, softer demand from spot exchange-traded funds, and fresh selling from Strategy. Together, they explain why price action has stayed weak even as some buyers remain on the sidelines.
1. Coldcard’s vulnerability is the first shock
The most immediate concern is the Coldcard hardware wallet issue tied to Coinkite. The warning does not mean every Coldcard device is exposed; it applies to a specific set of wallets whose seed phrases were created on vulnerable firmware. That distinction matters because the incident is targeted, not universal.
Losses linked to the exploit have grown in stages. Early estimates pointed to nearly $40 million in bitcoin being drained, and later reports added two more attack waves. The total has now reached 1,367.05 BTC, or about $88.6 million. Galaxy Digital’s Alex Thorn later flagged a fourth coordinated wave, saying the transaction pattern matched vulnerable Coldcard UTXOs and that the activity gave him high confidence that another attack was underway. His message to affected users was blunt: move the coins immediately, since roughly 449 BTC may still be at risk from that wave alone.
The damage is not only financial. Santiment says the incident pushed Bitcoin’s positive-to-negative sentiment ratio across X, Reddit, and Telegram to its lowest level since the firm began tracking the data. That kind of mood shift often shows up when short-term traders become less willing to buy dips.
2. ETF demand has lost momentum
Institutional demand through spot Bitcoin ETFs has also turned uneven. June was the weakest month on record for the category, but July started with a rebound of almost $200 million in net inflows during the first week. That suggested institutions were stepping back in after a soft patch.
The recovery did not hold its pace. Inflows slowed by mid-month, then seven straight days of net buying ran from July 14 to July 22, which was the longest such streak since April. After that, the trend flipped again and net outflows returned, taking some of the earlier strength out of the market. SoSoValue had not yet published August flow data at the time of the latest reading, so the current picture is still incomplete.
This matters because spot ETFs are the main route for conservative capital that wants regulated exposure without direct custody. That includes pension funds, hedge funds, and other institutional allocators. With the Coldcard issue still unfolding, the appeal of regulated products from issuers such as BlackRock, Fidelity, Bitwise, and Franklin Templeton may stay elevated for those investors.
3. Strategy has added more selling pressure
A third source of pressure came from Strategy, where Michael Saylor said the company raised its USD reserve by $250 million and completed an $81 million buyback of STRC shares. Buried beneath those updates was a more market-sensitive move: the firm sold 1,637 BTC for about $105 million between July 27 and August 2.
That reduced Strategy’s holdings from 843,775 BTC to 842,138 BTC. The drop is small in percentage terms, but it stands out because the company has long been viewed as a persistent accumulator rather than a seller. Even a modest reduction can affect sentiment when traders are already watching for signs of weaker corporate demand.
- The security incident weakened confidence among retail holders.
- ETF flows shifted from rebound to outflow.
- Strategy’s sale added another source of supply.
Bitcoin was trading near $63,600, according to CoinGecko, which put the weekly change at roughly minus 1 per cent. Seasonality does not help either. August has finished lower in 9 of the past 13 years, so the month has a weak track record even before the current mix of negative catalysts is added. For now, the market looks more vulnerable to volatility than to a fast recovery.
