According to @lookonchain, wallet bc1ql7c transferred its entire 6,500 BTC, valued at $694M by @lookonchain, to multiple new wallets after roughly three years of inactivity, with the activity and address details corroborated on the Arkham Intelligence explorer for bc1ql7c3k2xw90qmhpntte94mu7mpra6g77nqtj6v7 (source: @lookonchain; source: Arkham Intelligence). According to @lookonchain, these 6,500 BTC were originally received from Aleksandr Bilyuchenko (also known as Ivanov) about three years ago (source: @lookonchain). The U.S. Department of Justice has publicly accused Aleksandr Bilyuchenko of roles in BTC-e and WEX and of laundering Mt. Gox’s stolen bitcoin, which informs counterparty and compliance risk assessment if any of these coins later touch exchanges (source: U.S. Department of Justice, 2023 charging documents). For trading, monitor whether the newly created wallets forward coins to known exchange deposit addresses because spikes in BTC exchange inflows have historically aligned with short-term sell pressure and volatility (source: CryptoQuant research on exchange inflows and price behavior), and set real-time on-chain alerts on the Arkham Intelligence address cluster to track subsequent hops (source: Arkham Intelligence).
