Quick Summary
- Law enforcement agencies cracked open a Bitcoin wallet inactive for approximately nine years
- Authorities transferred 500 BTC valued at roughly $35 million to Coinbase on March 24, 2026
- The cryptocurrency belonged to Clifton Collins, a cannabis cultivator who concealed his private keys inside a fishing rod container
- Officials presumed the keys were destroyed when Collins’ possessions were discarded at a landfill after his 2017 detention
- Law enforcement officials are optimistic the identical technique will provide access to 11 additional wallets containing over €330 million
The Criminal Assets Bureau (CAB) of Ireland, working alongside Europol, has gained access to a Bitcoin wallet that remained untouched for almost ten years. The wallet’s contents—500 BTC valued at approximately $35 million—were moved through blockchain networks on March 24 before being deposited into Coinbase.
This digital wallet was owned by Clifton Collins, a Dublin resident 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.
Collins acquired 6,000 Bitcoin during 2011 and 2012, a period when cryptocurrency prices remained in the single-digit dollar range. His marijuana cultivation profits financed these digital asset purchases.
He distributed his 6,000 BTC holdings evenly among 12 separate wallets, allocating 500 BTC to each one. Collins documented the private keys on one piece of paper, which he then concealed within a fishing rod container at his Galway rental residence.
Authorities apprehended Collins in 2017 following the discovery of cannabis during a standard traffic inspection. Subsequently, his property owner emptied the premises and disposed of Collins’ possessions at a waste facility.
The fishing rod container—along with the sole copy of the private keys—was almost definitely destroyed. Collins later indicated that a burglary at his residence might have also contributed to the loss.
In 2020, Ireland’s High Court mandated the seizure of the Bitcoin holdings. At that time, the 6,000 BTC carried a value near €53 million. Current valuations place the total at approximately €360 million.
Despite the judicial mandate, CAB possessed no means to retrieve the cryptocurrency without the private keys. Both law enforcement and Collins concluded the Bitcoin was permanently inaccessible.
The Method Behind the Breakthrough
CAB and Europol have not revealed the precise methodology used to breach the wallet. Europol stated only that it supplied “highly complex technical expertise and decryption resources.”
One hypothesis suggests Collins may have saved his keys within an encrypted document secured by an insufficient password, which authorities potentially cracked using brute-force techniques.
An alternative explanation involves Collins potentially using a compromised tool for generating his 12 key pairs. A defective random number generator might create predictable keys, enabling investigators to recreate them.
Authorities reportedly express confidence that this identical approach will work on the remaining 11 wallets.
Outstanding Assets Still Inaccessible
Collins presently retains control over 5,500 Bitcoin, valued at approximately $389 million based on Arkham intelligence.
Should CAB successfully unlock every remaining wallet through this same methodology, the complete 6,000 BTC recovery would represent the bureau’s most substantial single asset confiscation ever recorded.
The 500 BTC transferred on March 24 represents the first verified access to Collins’ wallets since his arrest nine years earlier.
