Bitcoin's long-term holder supply has climbed to an all-time high of approximately 16.64 million BTC, according to CoinGlass tracking data published July 21. The metric counts coins held for at least 155 days and serves as a proxy for investor conviction and reduced selling pressure.
Long-term holder accumulation has accelerated as spot bitcoin ETF inflows and institutional adoption have shifted the composition of bitcoin's on-chain ownership away from shorter-duration traders. The prior record for LTH supply stood at 16.5 million BTC. Bitcoin Magazine Pro on-chain data confirmed the July 21 reading.
Long-term holder supply is a closely watched on-chain metric because it measures the proportion of bitcoin circulating supply held by investors unlikely to sell into near-term price weakness. As LTH supply grows, the float available to traders shrinks.
The supply cohort has grown steadily since late 2022. Spot bitcoin ETF launches in January 2024 in the United States created a new institutional ownership channel that favored buy-and-hold strategies over active trading. Holdings in U.S. spot ETFs have surpassed 1 million BTC as of mid-2026, and a significant portion entered the long-term holder category within their first year of purchase.
On-chain data providers including Glassnode, IntoTheBlock, and CoinGlass track this metric using time-weighted UTXO analysis, measuring the age of unspent transaction outputs to infer holding duration. Disagreement between providers sometimes arises from different methodologies for classifying moved coins, though directional trends tend to align across sources.
The record LTH supply figure arrived as bitcoin held near $68,500 following renewed volatility in equity markets. Short-term holder supply, which counts coins held fewer than 155 days, has remained relatively flat since May.
Each percentage point of bitcoin's 21 million coin supply locked into long-term holder status removes approximately 210,000 BTC from active trading circulation. At 16.64 million coins, LTH supply now represents 79.2% of circulating bitcoin, up from 78.9% two weeks prior. The metric that decides whether this trend continues is whether spot ETF inflows maintain their current monthly pace; a sustained monthly inflow below $500 million would likely slow the LTH accumulation cycle.
