According to @lookonchain, dormant Bitcoin address 1Au1uZ transferred 1,000 BTC valued around 89 million USD to a new wallet roughly two hours before Dec 5, 2025, indicating a significant whale move that could affect market monitoring, source: Lookonchain on X. According to @lookonchain, the address originally received 1,000 BTC about 14 years ago when BTC traded near 3.88 USD, implying an initial value close to 3,883 USD, source: Lookonchain on X. According to BitInfoCharts address data, on-chain records for 1Au1uZ show an outbound transaction of 1,000 BTC to a fresh address, confirming the transfer size and timing, source: BitInfoCharts address page for 1Au1uZ. According to Glassnode on-chain research, such movements increase old-coin activity measured by Coin Days Destroyed, a metric that rises when long-dormant BTC moves and is used to track shifts in coin age dynamics, source: Glassnode on-chain metrics documentation. According to CryptoQuant analytics, traders typically monitor subsequent exchange inflows after whale transfers to gauge potential near-term sell pressure via exchange flow dashboards, source: CryptoQuant exchange flow metrics.

According to the source, a social post claims Satoshi’s BTC wallet is now worth over $135B and would rank among the top 10 global fortunes (source: public social post dated Oct 5, 2025). However, no single Satoshi wallet has been identified by rigorous on-chain research, and early-mined coins attributed via the Patoshi pattern are estimated around 1.1 million BTC distributed across many addresses (source: Sergio Demian Lerner – The Patoshi Mining Machine, bitslog.com). Rich-list data shows the largest individual BTC addresses are exchange or custody wallets and do not approach a 1.1 million BTC balance (source: BitInfoCharts Bitcoin Rich List). For trading, the material signal is movement from Patoshi-era coins, which in past instances coincided with heightened market volatility and media attention (source: Chainalysis Blog analysis of the May 2020 movement of 50 BTC from 2009-era coins). Traders can monitor dormant supply and coin days destroyed to detect aging UTXO activity that can precede market swings (source: Glassnode Academy – Coin Days Destroyed and Dormancy). Set alerts on early-mined address clusters and track flows to exchanges to manage gap risk around sudden BTC supply changes (source: Arkham Intelligence platform features and Glassnode Alerts).

According to glassnode, BTC's Short-Term Holder Coin Days Destroyed (CDD) has reached -12.8K coin days/hr, indicating a significant fear-driven sell-off. This metric, adjusted with the Spent Output Profit Ratio (SOPR), mirrors the market conditions of August 2024, suggesting a similar economic weight of spent coins during sell-offs.

According to @glassnode, Bitcoin's URPD shows a filling liquidity gap when comparing February 23 to today. Although URPD lacks behavioral context, Coin Days Destroyed (CBD) provides insights into investor behavior, revealing which investors lowered their cost basis, capitulated, and where new demand has emerged.
