Key Highlights
- A cryptocurrency wallet untouched for almost ten years was successfully accessed by Irish authorities with Europol assistance
- Approximately $35 million in Bitcoinâtotaling 500 BTCâwas transferred to Coinbase on March 24, 2026
- The digital assets belonged to Clifton Collins, a cannabis cultivator who concealed access keys inside a fishing rod case
- The private keys were presumed permanently lost when Collins’ possessions were disposed of at a landfill after his 2017 detention
- Law enforcement officials are confident their breakthrough technique will work on the 11 remaining wallets valued at more than âŹ330 million
The Criminal Assets Bureau (CAB) of Ireland, working alongside Europol, has achieved a breakthrough in accessing a cryptocurrency wallet that remained inactive for approximately ten years. On March 24, authorities moved 500 BTCâcurrently valued at roughly $35 millionâthrough blockchain transactions before depositing the funds into Coinbase.
The digital wallet’s owner, Clifton Collins, is a Dublin resident who was found guilty of orchestrating large-scale cannabis growing operations throughout several Irish counties over more than ten years. Before his criminal enterprise, Collins maintained employment as both a security professional and apiarist.
Between 2011 and 2012, Collins acquired 6,000 Bitcoin during a period when cryptocurrency prices remained in the single-digit dollar range. His drug trade profits financed these digital currency purchases.
He distributed the 6,000 BTC evenly among a dozen separate wallets, allocating 500 BTC to each. The private keys for all wallets were documented on one piece of paper, which he then concealed within a fishing rod container 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 premises and disposed of Collins’ belongings at a waste facility.
The fishing rod containerâholding the sole record of the private keysâwas almost certainly destroyed in the disposal process. Collins has indicated that a burglary at the rental property might have also contributed to the keys’ disappearance.
In 2020, Ireland’s High Court mandated the seizure of the Bitcoin holdings. The 6,000 BTC carried an estimated value of âŹ53 million at that time. Current valuations place the total at approximately âŹ360 million.
Despite the judicial confiscation order, CAB lacked the technical means to retrieve the cryptocurrency without possession of the private keys. Both law enforcement and Collins had concluded the Bitcoin was irrecoverable.
The Method Behind the Breakthrough
The specific technique used by CAB and Europol to penetrate the wallet remains undisclosed. Europol’s statement mentioned only that they delivered “highly complex technical expertise and decryption resources.”
One hypothesis suggests Collins may have preserved his keys within an encrypted document secured by an insufficient password, which authorities potentially compromised using brute-force computational methods.
An alternative explanation involves the possibility that Collins employed a defective application to create all twelve key combinations. A compromised random number generator could have produced keys following predictable patterns, enabling investigators to reverse-engineer them.
Authorities have expressed strong confidence that their successful methodology can be replicated for the remaining eleven wallets.
Outstanding Cryptocurrency Holdings
According to Arkham intelligence, Collins retains control over 5,500 Bitcoin, currently worth approximately $389 million.
Should CAB successfully unlock every remaining wallet through the same approach, recovering the complete 6,000 BTC would represent the bureau’s largest single asset confiscation on record.
The March 24 transfer of 500 BTC constitutes the first verified access to any of Collins’ cryptocurrency wallets since authorities arrested him nine years earlier.
