Irish authorities recover another 500 BTC from lost Bitcoin of convicted drug trafficker Clifton Collins
The Irish Criminal Assets Bureau (CAB) stated that it has recovered another 500 BTC, worth nearly $31 million, from the lost crypto assets of convicted drug trafficker Clifton Collins. To date, the agency has recovered a total of 1,500 BTC in this case, valued at over $92 million at current prices.This operation was supported by Europol's European Cybercrime Centre. Europol stated that it organized operational meetings at its headquarters in The Hague and provided investigators with complex technical support and decryption resources to help them access the relevant wallet assets.The case involves 12 Bitcoin wallets accumulated by Collins from the proceeds of selling and cultivating cannabis, which initially held a total of 6,000 BTC. Previously, Irish authorities had recovered 500 BTC each in March and May.Arkham data shows that approximately 4,500 BTC remain in dormant wallets, valued at over $275 million.
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. Currently, the market value of Nakamoto’s Bitcoin holdings has declined by over 35%, and its stock price has plunged 99.4%, falling from $1,000 (post-split adjusted) to $5.60. 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. His wealth primarily stems from his BitMEX equity, his family office Maelstrom fund, and potential undisclosed token investments. 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. Despite navigating regulatory controversies, he remains influential in the crypto industry, particularly active in innovating perpetual swaps and sharing market perspectives.Overall, Arthur Hayes is still regarded as a key opinion leader in the crypto market, with his asset structure closely correlated to market cycles.

A wallet dormant for 2 months has reactivated, accumulating over $100,000 worth of ANSEM in 7 hours
According to Arkham monitoring, a wallet that had been dormant for about 2 months has recently reactivated. It transferred over $100,000 in funds from Ethereum to Solana via a cross-chain bridge. Subsequently, within just 7 hours, the address accumulated a total of 529,160 ANSEM tokens. The current value of its holdings is approximately $101,450, representing 0.05291% of ANSEM's total supply. This makes it the 130th largest holder of the token. Analysis indicates that this large-scale buying activity by the address may signal the start of a new round of capital deployment, although it is currently too early to confirm whether it represents a broader accumulation trend.

According to Odaily, monitored by Stalkchain, a group of addresses suspected to belong to a whale accumulated a total of 10.34 million $ANSEM through 6 wallets over the past few days, with an investment of approximately $2.551 million. All holdings were subsequently sold today, resulting in a final loss of about $60,700.On-chain tracking data from Arkham and other platforms shows that the wallet cluster initially built its position through 4 addresses in batches:3 days ago, address Eo3ck...EhWQ purchased 827,000 $ANSEM, valued at approximately $225,000;Address CzZF7...RE74C bought 668,000 tokens, valued at about $191,000;Address FY8nW...b9L5Ag acquired 758,000 tokens, valued at approximately $215,000;2 days ago, address BMRse...25rHT purchased 641,000 tokens, valued at about $184,000.The aforementioned 4 wallets held a cumulative total of 2.894 million $ANSEM (approximately $814,600), all of which were subsequently transferred to the main wallet GFsqy...26SM.This main wallet then further purchased 7.535 million $ANSEM, valued at approximately $1.737 million, bringing the total holdings of the entire wallet cluster to 10.34 million tokens, worth about $2.551 million.However, the whale subsequently began to unwind its position:The main wallet sold 6.938 million $ANSEM, receiving approximately $1.943 million;The remaining 3.491 million tokens were transferred to wallet 62dT...LrUE;About 2 hours later, this wallet sold all 3.491 million $ANSEM, receiving approximately $546,900.Ultimately, the wallet cluster completed its full liquidation. Based on on-chain transaction data, this trading activity resulted in a loss of approximately $60,700.
The US government transferred $288 million in seized BTC and ETH to Coinbase Prime
Odaily News According to on-chain tracking platform Arkham, the US government on Monday transferred a total of $288.33 million in seized BTC and ETH to Coinbase Prime, including approximately 3,800 BTC valued at $235 million and around 30,000 ETH valued at $53 million. The assets originated from criminal cases involving Brian Krewson, BTC-e, and Ryan Farace. Tim Sun, Senior Researcher at HashKey, stated that Coinbase Prime serves as the custodian for the US government, and it remains unconfirmed whether these transfers are preparation for sale or merely for the consolidation and custody of seized assets. Arkham tracking shows that the US government wallet still holds $20.6 billion in crypto assets, including 324,552 BTC. (Decrypt)
SpaceX Moves Bitcoin for First Time in Six Months, Sparking Attention, But On-Chain Data Shows No Signs of Selling
according to Arkham Intelligence monitoring, SpaceX recently conducted Bitcoin wallet activity for the first time in approximately six months. However, the transfers were extremely small in scale, and no BTC was sent to exchange addresses, indicating that the company is not selling Bitcoin.Data shows that three transfers were made from SpaceX-related wallets. The largest was 0.00213 BTC, valued at approximately $135; another transfer was 0.00139 BTC, worth about $89. Additionally, the Coinbase Prime custody service replenished 0.000738 BTC, worth around $47, to a SpaceX address, likely to cover on-chain transaction fees.Currently, SpaceX still holds approximately 18,712 BTC, with a total value of about $1.16 billion. Analysts believe that such small transfers are typically wallet maintenance operations, such as replenishing Gas fees, consolidating address funds, or testing signing processes, rather than typical asset-selling behavior.SpaceX completed its IPO on June 12, becoming one of the largest IPOs in history, and disclosed its Bitcoin holdings in a public filing for the first time. Previously, Arkham Intelligence could only track approximately 8,285 BTC belonging to SpaceX, but the company's disclosed holding of 18,712 BTC is more than twice the amount previously identified on-chain. According to the disclosure, SpaceX's Bitcoin purchase cost was approximately $661 million, with an average cost of about $35,000 per BTC.Six to seven months prior, SpaceX wallets had conducted a larger transfer, where the company moved approximately 1,000 BTC in batches between its own wallets and the Coinbase Prime custody address. However, that transfer similarly did not send funds to exchanges.Currently, Elon Musk's companies SpaceX and Tesla collectively hold over 30,000 BTC. The market generally believes that only if SpaceX transfers Bitcoin to known exchange deposit addresses in the future could it potentially signal an adjustment to its BTC treasury strategy or a potential sale.

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)
