Crypto Biz: Bitcoin’s $116M self-custody wake-up call
A $116 million Bitcoin wallet exploit puts self-custody under scrutiny as ETF inflows rebound, Strategy eyes more BTC and miners chase billions in AI deals.

A $116 million hardware wallet exploit has reopened one of Bitcoin’s oldest debates: Is holding your own keys worth the risk? Days later, US spot Bitcoin ETFs recorded their strongest inflows since April, prompting Bloomberg analyst Eric Balchunas to wonder whether security scares could eventually push more investors away from self-custody and toward ETFs.
Elsewhere, Strategy is preparing to resume Bitcoin purchases after a rare bout of selling, Riot Platforms is reportedly turning its mining infrastructure into a $9 billion AI deal, and Trump Media is rethinking its crypto treasury strategy after a $238 million quarterly loss.
Strategy CEO says company will resume Bitcoin accumulation this year
Strategy CEO Phong Le said the company plans to resume Bitcoin accumulation later this year, seeking to reinforce its long-term strategy after a series of relatively small sales drew scrutiny over its once-firm “never sell” stance.
Le told FOX Business that Strategy bought roughly 175,000 BTC and sold about 7,000 BTC this year — about 25 times more buying than selling. The company now holds more than 840,000 BTC, making it the largest institutional holder, but has sold Bitcoin on four occasions since May, most recently unloading 1,690 BTC to support preferred dividends, buybacks and its dollar reserve.
Those sales have highlighted the competing demands facing Strategy as it balances its Bitcoin accumulation strategy with obligations to common and preferred shareholders. The treasury model has also come under pressure. According to Novaque Research, when companies trade below Bitcoin net asset value, raising capital becomes increasingly dilutive and the financing cycle harder to sustain.

Bitcoin ETF demand rebounds as self-custody risks come into focus
US spot Bitcoin ETFs attracted roughly $1 billion in net inflows for the week, signaling renewed institutional demand even as Bitcoin’s price remains subdued and a major hardware wallet exploit puts fresh attention on the risks of self-custody.
Bloomberg ETF analyst Eric Balchunas said it was the third-best week since October, a period he described as Bitcoin’s “silent IPO,” a term popularized by investor Jordi Visser. The theory holds that early investors have been selling into growing ETF and institutional demand, creating enough supply to keep Bitcoin subdued despite fresh capital entering the market.
The rebound also followed a Coldcard hardware wallet exploit linked to faulty key generation that drained about $116 million in Bitcoin. Balchunas said the incident could ultimately bolster ETFs’ appeal among investors concerned about self-custody risks, pointing to post-hack inflows as a possible, though unproven, connection.
He cautioned that correlation does not imply causation, but added that “long-term I can’t imagine there aren’t some who migrate over.”

Anthropic reportedly struck a $9 billion compute deal with Bitcoin miner Riot
Anthropic reportedly struck a $9 billion deal with Riot Platforms for 191 megawatts of capacity from the Bitcoin miner’s Texas campus, highlighting how access to power is becoming increasingly valuable as AI data centers face capacity constraints.
Riot said it secured a 20-year agreement to supply 191 megawatts from its Rockdale campus to a “leading frontier AI” company, which Bloomberg identified as Anthropic. The deal follows Anthropic’s $19 billion TeraWulf data center lease and adds Riot to a growing list of Bitcoin miners expanding into AI, including Bitdeer, CleanSpark, MARA Holdings, Core Scientific, Hut 8 and IREN.
Riot shares fell 5.4% Monday before rising 21% overnight and are up roughly 50% year-to-date. The fourth-largest Bitcoin miner has a $7.33 billion market capitalization, while Bernstein said partnerships between AI companies and miners could help address the power crunch constraining data center expansion.
Trump Media to revamp crypto treasury strategy after $238 million Q2 loss
Trump Media said it will revamp its digital asset treasury strategy after unrealized losses on crypto and securities helped push the company to a $238 million second-quarter net loss, highlighting the balance-sheet risks of corporate crypto holdings.
The company reported $190.4 million in unrealized losses across its digital assets, and pledged digital assets and equity securities in the second quarter. It held 9,477.16 Bitcoin as of June 30, down from 9,542.16 the prior quarter. In July, it sold $159.6 million in Bitcoin-related securities and used the proceeds to buy more Bitcoin, bringing its holdings to about 14,139 BTC worth $890.5 million by July 31.
Trump Media warned that generating additional income from its Bitcoin holdings could expose it to counterparty risk, particularly if a partner should default or become insolvent. In some cases, the company could be unable to recover Bitcoin committed under unsecured arrangements. It also plans to direct more resources to Truth Social, Truth+ and other media operations as part of a broader shift in capital allocation.
