2009-Mined Bitcoin Wallet Breaks 14-Year Silence With 150 BTC Transfer

Analysts frame the transfer as security housekeeping prompted by legacy address vulnerabilities.

Overview

  • Wallet 18eY9o sent 150 BTC worth roughly $16–16.6 million in its first movement since 2011 and still holds about 4,000 BTC valued near $442 million.
  • On-chain trackers including Lookonchain and Nansen flagged the single transaction, noting the coins were mined in 2009 and consolidated into the address in 2011.
  • Experts cite risks tied to early address types that expose public keys, with some recommending moves to fresh wallets to reduce potential quantum attack exposure.
  • Market impact is seen as minimal given daily Bitcoin trading volumes above $20 billion and prices hovering near $111,000 unless funds are traced to exchange wallets.
  • The activity fits a 2025 pattern of early-holder rotations, including an approximately 80,000 BTC sale brokered by Galaxy Digital, with one analyst suggesting this owner once controlled closer to 8,000 BTC across related addresses.
