The Nasdaq-listed company relies largely on staking rewards to fund operations, while its 0G holdings were valued 91% below their recorded costs.

The company also posted an $82.5 million fair value loss on digital assets and a net loss of $61.3 million for the first half of 2026. ZeroStack said its 75.1 million Zero Gravity (0G) tokens had an aggregate cost of $163.3 million and a fair value of $15.2 million as of June 30, leaving the holdings valued about 91% below their recorded costs.

The persistent discount suggests US spot buyers have remained less aggressive than overseas traders even as US Bitcoin ETF inflows turned positive in July. Bitcoin fell under $63,000 on Monday as the Coinbase Premium Index, a proxy for US institutional demand for Bitcoin, reached its 77th day in the red. Bitcoin has traded at a persistent discount on Coinbase relative to international exchanges since May 19, with the latest premium rate at -0.1369%, according to Coinglass.

The five-year bug escaped detection because auditors verified that the intended random number generator existed, but not that it was being called. Coldcard’s five-year seed-generation flaw has exposed a broader weakness in how hardware wallets are independently tested, according to Kraken chief security officer Nick Percoco. In an X post on Sunday, Percoco said the incident should be a “wake-up call” for hardware-wallet makers, calling for independent testing to verify that the approved source of randomness is the one actually used by production firmware. “Consumers are asked to trust a manufacturer’s implementation of the single most critical function in the system, with no independent verification that the approved entropy path is the one actually executing,” said Percoco.

Stablecoins have been flowing out of South Korean exchanges for 18 consecutive months as regulators weigh tighter oversight of cross-border crypto activity. South Korea saw 560.3 billion won ($367 million) in stablecoin outflows to overseas exchanges in June, extending the country’s streak of monthly net stablecoin outflows to 18 consecutive months. The figure comes from Financial Supervisory Service (FSS) data obtained by Yonhap News Agency through People Power Party lawmaker Lee Jong-wook. South Korea’s five major crypto exchanges — Upbit, Bithumb, Coinone, Korbit and Gopax — transferred 2.7 trillion won ($1.81 billion) in stablecoins offshore in June and received 2.2 trillion won ($1.44 billion) from foreign platforms. Market participants cited by Yonhap attributed the transfers to demand for products restricted or unavailable on domestic exchanges, such as overseas derivatives, tokenized real-world assets (RWAs), decentralized finance and staking products.

The “sickening” loss of $90 million of Bitcoin from cold storage weighs heavily on sentiment, as the Clarity Act stalls with just five days left to hold a Senate vote. After $90 million in Bitcoin was drained from Coldcard wallet users, small hodlers desperately sought refuge on centralized exchanges and via alternative custody methods. Bitcoin transfers below 1 BTC climbed to their highest daily level since 2022 on Friday, with 39,600 BTC moved, according to data shared by CryptoQuant head of research Julio Moreno on Saturday.

Galaxy Research, the research arm of crypto investment company Galaxy Digital, reported Saturday that the third wave of attacks on users of the hardware wallet on the weekend brought estimated losses to 1,367 BTC ($88.6 million) across 4,585 addresses.
