Key Points
- Authorities successfully accessed a Bitcoin wallet that remained untouched for almost a decade
- Approximately 500 BTC valued at roughly $35 million was transferred to Coinbase on March 24, 2026
- The cryptocurrency belonged to Clifton Collins, a convicted cannabis cultivator who concealed his private keys in fishing equipment
- The access credentials were presumed destroyed when Collins’ possessions were discarded at a waste facility after his 2017 detention
- Law enforcement officials are confident they can apply the same technique to access 11 additional wallets containing over €330 million
The Criminal Assets Bureau (CAB) of Ireland, working alongside Europol, has managed to break into a Bitcoin wallet that remained inactive for close to ten years. The cryptocurrency holdings—500 BTC valued at approximately $35 million—were transferred on-chain on March 24 and deposited into Coinbase.
The digital assets belonged to Clifton Collins, a resident of Dublin who was found guilty of operating large-scale cannabis growing facilities throughout several Irish regions for more than ten years. Prior to his criminal enterprise, Collins maintained employment as both a security professional and apiarist.
Between 2011 and 2012, Collins acquired 6,000 Bitcoin when the cryptocurrency’s value remained in the single-digit dollar range. His cannabis operation profits financed these digital currency purchases.
Collins distributed his 6,000 BTC holdings evenly among a dozen separate wallets, placing 500 BTC in each one. He documented the private keys on one piece of paper and concealed it within fishing rod equipment stored at his leased residence in Galway.
Authorities apprehended Collins in 2017 following the discovery of cannabis during a standard vehicle inspection. Subsequently, his property owner emptied the rental unit and disposed of Collins’ personal items at a municipal landfill.
The fishing rod container—along with the sole copy of the access credentials—was almost certainly eliminated. Collins later indicated that a possible burglary at his residence might have also contributed to the loss.
In 2020, an Irish High Court mandated the forfeiture of the Bitcoin holdings. The 6,000 BTC was valued at approximately €53 million at that time. Current valuations place the total near €360 million.
Despite the judicial directive, CAB possessed no mechanism to retrieve the cryptocurrency without the private keys. Both law enforcement agencies and Collins accepted that the Bitcoin was permanently inaccessible.
The Method Behind the Breakthrough
CAB and Europol have not revealed the specific methodology employed to gain wallet access. Europol stated only that it contributed “highly complex technical expertise and decryption resources.”
One hypothesis suggests Collins may have saved his credentials in an encrypted document secured with an inadequate password, which authorities potentially compromised using brute-force methods.
An alternative explanation involves the possibility that Collins utilized a defective application to create all twelve key pairs. A compromised random number generator could yield predictable credentials, enabling investigators to reproduce them.
Law enforcement personnel have expressed strong confidence that the identical approach will succeed with the remaining eleven wallets.
Remaining Cryptocurrency Holdings
Collins maintains control of 5,500 Bitcoin, currently valued at approximately $389 million based on Arkham intelligence.
According to Arkham, among the 6,000 BTC held by Irish drug dealer Clifton Collins—previously believed to be permanently lost—500 BTC (worth about $35.44 million) were moved on March 24 at 12:51 after nearly 10 years of dormancy and transferred into Coinbase.

Should CAB successfully access all outstanding wallets through the same methodology, the complete 6,000 BTC recovery would represent the bureau’s largest individual asset confiscation to date.
The 500 BTC transaction executed on March 24 represents the first verified access to Collins’ wallet infrastructure since his apprehension nine years earlier.
