A significant security vulnerability in Coldcard, a well-known Bitcoin hardware wallet manufacturer, became a leading topic in the cryptocurrency sector last week. The firmware exploit, which affected some Coldcard devices, reignited industry discussions about the importance of self-custody and operational security for digital assets.

AAPLInstitutional inflows to Bitcoin ETFs rise sharply
While debates over security and custody intensified, institutional investors continued to allocate capital to US spot Bitcoin exchange-traded funds (ETFs). Data from the Bitcoin For Corporations ETF Dashboard revealed that across seven trading days, spot Bitcoin ETFs in the US recorded $790.6 million in net inflows. During this period, over $1.0 billion flowed into the funds, while $212.7 million exited, marking one of the strongest weekly inflow periods in recent months.
The inflow statistics do not directly explain investor motivations for purchasing Bitcoin. However, despite ongoing headlines about hardware wallet risks, large investors appeared to favor regulated Bitcoin investment products.
Positive momentum outweighs single outflow session
The seven-day flow patterns demonstrated resilience. On July 31, spot Bitcoin ETFs experienced $212.7 million in net outflows, representing the only day of negative flow in the week. Buying resumed almost immediately, with the next four trading sessions each showing gains: $170.1 million on August 3, $207.8 million on August 4, $241.6 million on August 5, and $99.4 million on August 6.
By week’s end, the cumulative inflows had more than offset the mid-week outflows, highlighting the continued demand for these products.
| Trading Day | Net Inflow/Outflow |
|---|---|
| July 31 | -$212.7M |
| August 3 | +$170.1M |
| August 4 | +$207.8M |
| August 5 | +$241.6M |
| August 6 | +$99.4M |
During a week dominated by security news, institutional capital steadily flowed into regulated Bitcoin ETFs, with net inflows totaling $790.6 million.
BlackRock’s IBIT drives majority of inflows
BlackRock, the global asset management giant, once again led the ETF inflows through its iShares Bitcoin Trust (IBIT). Over the seven-day reporting period, IBIT secured $757.5 million in rolling net inflows, extending its streak to four consecutive days of gains. On the final trading session alone, IBIT accounted for $128.3 million in positive flow.
Other ETF providers also contributed. Fidelity’s Wise Origin Bitcoin Fund (FBTC) brought in $11.2 million during the same session, while Bitwise’s BITB saw $1.7 million in net inflow. Some funds did record modest outflows, but these were small compared to IBIT’s strong performance.
IBIT maintained its position at the forefront of US Bitcoin ETF inflows, with other issuers such as Fidelity and Bitwise also registering gains.
The overall effect was sustained positive movement into Bitcoin ETFs, with broad participation across several major funds.
ETF flows indicate robust institutional demand
ETF flows provide a clear measure of institutional activity in Bitcoin markets. Although they do not clarify the underlying reasons for investor behavior, they do reflect actual capital movement. Throughout the week marked by security concerns, institutional appetite for Bitcoin—channeled through regulated ETFs—remained resilient.
The Coldcard firmware exploit highlighted specific operational risks associated with hardware wallets, but ETF investors appeared focused on their longer-term strategies and risk management via regulated platforms.
Mini dictionary: Coldcard is a hardware wallet developed by Coinkite, designed for secure offline storage of Bitcoin. Hardware wallets use physical devices to safeguard private keys, reducing the risk of remote hacks but requiring careful operational security by users.
This divergence reinforces that a security incident affecting one custody approach may not always have immediate or broad impact on institutional adoption of Bitcoin via ETFs.
Tracking ETF flows in real time
Daily flow data remains one of the most important metrics for analyzing institutional adoption of Bitcoin. The Bitcoin ETF Dashboard, compiled by Bitcoin For Corporations, offers a transparent view of daily net inflows and outflows, issuer performance, and market concentration metrics. These indicators help investors monitor capital allocation trends, distinguish between temporary headlines and lasting market shifts, and make data-driven decisions.
As new data becomes available each trading day, these dashboards provide up-to-date insights into institutional sentiment and behavior in US spot Bitcoin ETFs.
