ARK 21Shares ETF Inflows Surge Following Coldcard Wallet Breach
Key Facts
Amid escalating concerns over digital asset security, the cryptocurrency sector has witnessed a notable shift toward regulated investment vehicles. The ARK 21Shares Bitcoin ETF recorded substantial inflows totaling $620 million, according to analyst reports. This momentum follows a security breach at Coldcard wallets, which prompted investors to seek safer alternatives to self-custody solutions.
According to available data, the security flaw in Coldcard hardware wallets rattled confidence in traditional cold storage, enhancing the appeal of spot ETFs as institutional-grade options. This shift coincided with major US economic data on July 30, 2026, where the Core PCE Price Index rose by 0.1%, coming in below the 0.2% forecast, providing a backdrop of relative stability in broader financial markets.
Traders should monitor continued liquidity flows into regulated ETFs as a signal of market maturation and institutional adoption. The market also awaits further security updates that may impact risk appetite in the digital asset sector in the coming days.
