Key takeawaysGlassnode data shows 210,000 BTC left long-term holder wallets in the past week, the largest single-week LTH decline since December 2024, as first reported by CoinDesk, attributed directly to the Coldcard firmware exploit. Glassnode data shows approximately 210,000 BTC exited long-term holder (LTH) wallets in the seven days ending August 7, 2026, the largest such outflow since December 2024. LTH supply fell from just under 15 million BTC to approximately 14.7 million BTC. What the On-Chain Data Actually ShowsGlassnode classifies long-term holders as entities whose coins have remained dormant for approximately 155 days. The 14.7 million BTC still classified as LTH supply represents coins that completed their migration and re-aged, or coins that haven't moved yet.
