Clifton Collins, a Dublin man and former award-winning beekeeper, ran a large-scale cannabis cultivation operation using rented houses across Ireland between 2011 and 2012 . He used the proceeds to purchase approximately 6,000 BTC when Bitcoin was still priced very low, and split the holdings across 12 separate wallets .
The Criminal Assets Bureau (CAB) first seized the 6,000 BTC in 2020 after securing a criminal forfeiture order, but could not access the funds because the private keys were considered lost or destroyed .
Collins claimed that after his 2017 arrest, he printed the private key codes on an A4 sheet of paper and hid them inside the aluminum cap of a fishing rod case . According to his account, a landlord later cleared out the property where the case was stored and sent the contents—including the fishing rod case with the keys—to a dump or incinerator . For years, the 6,000 BTC were treated as irretrievable .
In March 2026, Irish authorities—the CAB, in partnership with Europol's European Cybercrime Centre—achieved a technical breakthrough and successfully cracked the encryption on one of the 12 dormant wallets . On March 24-25, 2026, the first 500 BTC worth about $35 million was transferred out and sent to Coinbase Prime .
A second 500 BTC transfer, worth approximately $38 million, occurred in mid-May 2026 . The July 2, 2026 transfer of another 500 BTC (the third tranche) was confirmed by on-chain analytics firms including Arkham Intelligence .
According to Arkham data, approximately 4,500 BTC—worth roughly $277 million at current prices—remains in other dormant wallets still linked to Collins . The total originally seized from Collins was 6,000 BTC, of which 1,500 BTC have now been recovered across the three 2026 transfers .
The repeated transfers of seized BTC directly to Coinbase Prime—a platform commonly used by institutions for custody and liquidation—has been interpreted by market observers as a systematic, state-controlled liquidation of seized criminal assets . Each tranche of 500 BTC moved to a centralized exchange signals that the Irish government is methodically monetizing the crypto forfeiture rather than holding it. Such large deposits to exchanges can create downward price pressure, and the pattern of recurring tranches suggests the authorities have now established the technical means to gradually unlock and sell the remaining wallets .
