Key Takeaways
- • Bitcoin long-term holder supply has reached 16.75 million BTC, representing 17.7% of total Bitcoin supply held for 10+ years, according to Galaxy Digital Research Head Alex Thorn, signaling unprecedented accumulation by patient investors.
- • Realized market cap of long-term holders stands at $836.4 billion, indicating the aggregate value locked in by holders who acquired Bitcoin at an average cost basis of $50,000 per coin.
- • Long-term holders control approximately 79-80% of circulating Bitcoin supply, the highest share on record, creating structural scarcity in the available float and reducing selling pressure from this cohort.
- • The consolidation of supply among long-term holders provides foundational price support, as on-chain data shows minimal reactivation of dormant Bitcoin, suggesting conviction among institutional and retail holders despite price volatility.
Summary
Galaxy Digital's research team has documented that Bitcoin long-term holder metrics have simultaneously reached all-time highs across four key measurements, reflecting a fundamental shift in Bitcoin's ownership structure toward stronger hands. According to Alex Thorn, Head of Research at Galaxy Digital, the percentage of Bitcoin supply held for 10+ years has climbed to 17.7%, while the absolute quantity held by this cohort has reached 16.75 million BTC. This represents roughly 79-80% of circulating supply—the highest concentration on record, surpassing previous peaks reached in July 2025.
The realized market cap metric, which measures the aggregate acquisition cost of held Bitcoin, has reached $836.4 billion, with long-term holders carrying an average cost basis of $50,000 per coin. This figure is significant for institutional investors seeking to understand holder conviction; the substantial distance between current price levels and acquisition costs suggests that long-term holders have absorbed significant unrealized gains without liquidating, indicating strong conviction and reduced near-term selling pressure.
The tightening of circulating supply through long-term holder accumulation represents a structural change in Bitcoin's market dynamics. With the vast majority of available supply locked in by investors demonstrating multi-year holding periods, the float available for active trading has contracted meaningfully. On-chain analytics indicate that only minimal dormant Bitcoin has been reactivated, reinforcing the thesis that long-term holders remain committed to their positions. This supply constraint has historically served as a foundational support mechanism for Bitcoin's price during market cycles, reducing the likelihood of cascading liquidations from this ownership cohort.
For institutional investors evaluating Bitcoin's macro positioning, these metrics suggest that accumulation by sophisticated participants—typically institutions, funds, and high-net-worth individuals—continues to dominate over distribution. The alignment of record supply held by long-term holders with their elevated average cost basis indicates that these investors acquired substantial portions during previous market cycles and have maintained positions through subsequent volatility, a pattern consistent with conviction-based accumulation strategies rather than cyclical trading.
