Arkham: Nakamoto’s unrealized loss exceeds 35%, making it the worst-performing Bitcoin treasury company to date
Arkham posted on X stating that Nakamoto purchased approximately $679 million worth of Bitcoin at an average price of about $118,000 per BTC and has held it long-term without selling—except for a sale of 284 BTC at roughly $70,000 per BTC three months ago, resulting in cumulative losses of approximately $224 million. It is thus far the worst-performing Bitcoin treasury company.

Its actual peak stock price reached only around $30, subsequently dropping below $0.20, prompting a 1-for-40 reverse stock split to comply with Nasdaq listing requirements.
Arkham: Arthur Hayes' Net Worth Estimated Between $200 Million and $350 Million
Arkham has disclosed that BitMEX co-founder Arthur Hayes' estimated net worth in 2026 could range between $200 million and $350 million, with verifiable on-chain assets totaling approximately $42 million.

Although BitMEX has significantly declined from its 2019 peak (with an annual trading volume exceeding $1 trillion and a valuation of around $3.6 billion), its current valuation stands at approximately $500 million, yet it still constitutes a core component of his asset base.Arthur Hayes was previously sentenced in 2022 for violating the Bank Secrecy Act and was later pardoned by Donald Trump in 2025.

Taiko bridge attack may result in losses up to $1.7 million
Ethereum Layer 2 blockchain Taiko has stated its chain state verification mechanism has been compromised, and the security assumptions of all bridges deployed on Taiko can no longer be relied upon. It urges users to immediately withdraw funds from the relevant bridges. Taiko says it is coordinating with partners to control the incident and has suspended the affected systems.Crypto security firm Blockaid stated that the root cause appears to be a flaw in the way Taiko's bridge validates source signals. Attackers can submit message proofs on Ethereum that lack legitimate proof from the Taiko chain, thereby registering and withdrawing fraudulent bridge messages. This leads to the unauthorized release of assets from the ERC20 treasury. Blockaid estimates at least $1 million was stolen, while Lookonchain and PeckShield believe the value of stolen assets could be as high as $1.7 million.PeckShield reported that the attacker has transferred approximately 1.99 million TAIKO tokens to MEXC, valued at around $189,000. Data from blockchain intelligence firm Arkham shows that the Taiko attacker's wallet holds approximately $1.5 million in assets, primarily in Ether. (Cointelegraph)
