A group of long-dormant Bitcoin wallets moved 1,314.41 BTC over the past 24 hours, with the bulk of the activity tied to addresses created in 2014. According to the report cited by Odaily, wallets from that year transferred 1,214.42 BTC, accounting for 92.4% of the total and worth about $86 million at the stated valuation. The transactions included 21 transfers of 50 BTC each, with funds consolidated from legacy P2PKH wallets into new P2WPKH addresses. Some of the transfers were completed in the same block. Arkham’s entity labels did not show any link between the addresses and exchanges. The report also said the 2014 holder’s BTC had been acquired at roughly $310 to $427, implying gains of at least 16,645%. Separately, three wallets created in 2016 moved 79.99 BTC, while two 2017 addresses transferred 20 BTC. The information was attributed to Bitcoin.com News.

Bitcoin.com reported that 28 long-dormant Bitcoin wallets transferred a combined 1,314.41 BTC over the past 24 hours, with the haul valued at about $94.03 million. Wallets created in 2014 accounted for 1,214.42 BTC, or 92.4% of the total, worth roughly $86 million. The report said 21 transactions each moved 50 BTC, with funds consolidated from legacy P2PKH wallets into new P2WPKH addresses, and some of those transfers were confirmed in the same block. Arkham’s entity labels do not currently show any connection between the addresses and exchanges. Bitcoin.com also said the 2014 wallet holders had acquired their BTC at around $310 to $427, implying gains of at least 16,645% on those holdings. Separately, three wallets from 2016 moved 79.99 BTC, while two addresses from 2017 transferred 20 BTC.

A Bitcoin wallet created on Aug. 10, 2012 moved 212 BTC after 14 years of inactivity, according to an Odaily report citing Bitcoin.com News. Based on the price referenced in the report, the transferred holdings were worth about $13.72 million at the time of movement. The coins were originally valued at $2,346, or $11.07 per BTC. Using the article’s cited BTC price of $64,761, a full sale at that level would translate into a gain of 584,725%. The wallet owner has not been identified. The report said the 212 BTC was moved from a legacy Pay-to-Pubkey-Hash, or P2PKH, wallet to an unlabeled Bech32 wallet. The funds arrived in multiple batches before being consolidated. Bitcoin.com News also noted that a Coldcard vulnerability led to the theft of nearly 2,000 BTC, which may have prompted some long-term holders to relocate assets, though the address in this case has not been linked to any known entity.

CoinShares research says quantum risk to Bitcoin is overblown: only 8% of BTC sits in legacy P2PK addresses, and breaking encryption would require millions of qubits—decades away.

BitMEX Research proposes a quantum canary mechanism: a public bounty address that, if cracked by a quantum computer, automatically freezes legacy Bitcoin wallets. Critics argue attackers would avoid the trap, and setting the right bounty size is problematic.

A new report says quantum computers are still years, if not decades, away from threatening Bitcoin’s ECDSA. Older addresses are more exposed, developers are studying post-quantum options, and markets are still treating the issue as a distant risk.

Citi says advances in quantum computing are shortening the timeline for crypto security risks, with 6.5 million to 6.9 million BTC exposed through public keys and potentially vulnerable in the future.

A draft proposal called BIP-361 would phase out vulnerable legacy Bitcoin outputs and eventually freeze coins that are not moved, citing the long-term threat posed by quantum computing.
