Clifton Collins Bitcoin Wallet Transfers
Blockchain tracking by Arkham has identified five transfers from Bitcoin wallets labeled as belonging to Clifton Collins, including a fifth movement on Tuesday that Arkham counted as the largest number of transfers from the stash so far this year. In an October 20, 2026 post on X, Arkham reported that the five movements had totaled 2,500 BTC. Other addresses associated with the holdings still retain about 3,500 BTC, valued at approximately $288 million.
The first 500 BTC moved to Coinbase Custody in March, when the Bitcoin was worth roughly $35 million. On May 19, another 500 BTC, valued at $38 million, was sent to a different address. A third 500-BTC transfer reached Coinbase Custody within minutes on July 2. The fourth batch, worth about $39.5 million, moved on August 28 to the same address used for the July transfer. Tuesday’s movement brought the cumulative total to 2,500 BTC.
Arkham tagged Tuesday’s transfer to Collins and believes law enforcement was responsible. No agency has publicly confirmed that assessment. The distinction is important because the March transfer was connected to a seizure officially confirmed by Irish police, while Coinbase Custody is used by law enforcement agencies to hold seized assets.
How the First 500-BTC Wallet Became Accessible
Collins used money from trafficking cannabis to purchase approximately 6,000 BTC in 2011 and 2012. He divided the Bitcoin among 12 wallets, each containing 500 BTC. The seed phrases for the wallets were kept on a single sheet of A4 paper inside a fishing rod case.
After Collins was arrested in 2017, his landlord discarded his possessions into a trash heap. The fishing rod case and the keys inside it are believed to have gone to a landfill in County Galway. As a result, the Bitcoin was presumed lost for years. The first batch was later reported by Cryptopolitan on March 25, and Irish police confirmed the seizure in March.
“The Criminal Assets Bureau in collaboration with Europol gained access to and seized a cryptocurrency wallet containing 500 bitcoins, which are the proceeds of crime,” the Irish Garda said. The statement did not explain how the wallet had been opened.
Cryptopolitan reported that a defective key generator with poor randomization may have allowed investigators to work back to the private keys. The publication said the remaining wallets could potentially be opened through the same method if their keys had been generated from the same source. That remains an explanation advanced by Cryptopolitan rather than a technical account included in the Irish Garda’s statement.
Broader Movement of Dormant Bitcoin Wallets
Collins’ transfers are part of a wider movement involving older Bitcoin holdings. Twenty-four long-dormant wallets have awakened and moved 1,756.815 BTC, worth more than $145 million, so far in October. One of those wallets, first funded on September 11, 2013, sent 411.45 BTC valued at about $33.4 million, according to Cryptopolitan.
The 411.45-BTC wallet is also among the wallets named in New York’s “Noah Doe” suit. The lawsuit seeks a declaration that idle wallets containing around 3.8 million BTC are abandoned property. The plaintiffs do not possess the private keys required to transfer those coins, leaving the legal claim separate from the technical ability to move the Bitcoin.
Why This Matters
The Collins case shows how access to one wallet may have implications for other separately stored wallets if they were generated from the same source. Cryptopolitan’s defective-key-generator theory remains conditional, and the Garda did not disclose how investigators obtained access to the first wallet.
The broader significance also lies in what is confirmed and what remains unresolved. Irish authorities confirmed the March seizure, but Arkham’s view that law enforcement directed Tuesday’s transfer has not been officially corroborated. Roughly 3,500 BTC remain in other addresses linked to Collins, while the New York “Noah Doe” plaintiffs are pursuing a legal claim over around 3.8 million BTC without the private keys needed to transfer it. Together, the cases underscore how ownership, legal status, and technical control of dormant Bitcoin can remain separate issues even when large balances begin moving.
