Owner death — hardware wallet (2025)
BlockedCase description
A 2025 analysis cited in multiple estate planning publications estimated that between $140 billion and $200 billion in Bitcoin—representing 17–23% of circulating supply—was permanently lost, with a significant proportion attributable to holders who died without proper inheritance documentation. As Bitcoin's price exceeded $100,000 in late 2024 and rose further in 2025, the magnitude of the lost supply created measurable scarcity effects. Estate planning specialists reported a 40–60% increase in new client inquiries from Bitcoin holders seeking to establish inheritance arrangements, driven in part by media coverage of both the supply loss statistics and high-profile individual cases.
