$116M Bitcoin Wallet Exploit Sparks Self-Custody Debate Amid ETF Inflows

A $116 million hardware wallet exploit has reignited an old Bitcoin question: what is the real risk trade-off between self-custody and using regulated products? The debate is heating up as US spot Bitcoin ETFs post strong inflows, suggesting institutional capital may be finding ways to participate in Bitcoin without directly taking on custody and operational risk.

Meanwhile, major companies across the sector are making moves that underline how intertwined Bitcoin, corporate balance sheets, and emerging AI compute demand are becoming. Strategy is preparing to resume Bitcoin purchases after a rare period of selling, Riot Platforms is reportedly pursuing a large AI-focused compute arrangement tied to its mining footprint, and Trump Media says it will rethink its crypto treasury approach after a sizable quarterly loss.

Key takeaways

• A Coldcard-linked hardware wallet exploit drained about $116 million in Bitcoin, adding fresh fuel to the self-custody versus custody-by-others debate.
• US spot Bitcoin ETFs reportedly saw roughly $1 billion in net inflows for the week, with Bloomberg analyst Eric Balchunas calling it one of the strongest periods since October.
• Strategy CEO Phong Le said the firm plans to resume Bitcoin accumulation later this year after selling in multiple quarters to support shareholder-related obligations.
• Riot Platforms is reportedly arranging 191 megawatts of compute capacity for a “leading frontier AI” project at its Texas campus, highlighting the economic pull of power availability.
• Trump Media is revising its digital asset treasury strategy after recording large unrealized losses and reshaping how it funds and manages its Bitcoin exposure.
