Nearly four out of every five Bitcoin in existence are now sitting in wallets that haven’t moved them in a long time. K33 Research published findings on June 15 showing that long-term holders control 79% of BTC’s circulating supply, a record that has never been reached before.

The numbers behind the hoarding

The 79% figure is striking on its own, but the supporting data makes the picture even clearer. K33 found that only 218,421 BTC, coins that had been dormant for at least two years, were reactivated as of June 6, 2026. That is the lowest level of old-coin movement since 2012.

For context, consider where things stood two years ago. By the same date in June 2024, roughly 1.18 million BTC had been reactivated during what K33 describes as a prior distribution phase. The contrast is enormous: old hands were dumping coins in 2024. Now they are sitting on them.

The decline in reactivation has been accompanied by trading volumes and ETF outflows falling to their lowest levels of the year.

Where Bitcoin sits after the storm

This accumulation data arrives after a rough stretch for prices. Bitcoin went through roughly two weeks of significant declines in early June 2026 before stabilizing. By June 17, BTC was trading near $65,000, representing an approximate 6% rebound from recent lows.

K33’s historical analysis suggests that the current configuration of metrics, record-high long-term holder supply concentration, minimal dormant coin reactivation, and declining trading volumes, typically appears during the latter stages of a bear phase.

One significant macro wildcard looms over the market. The Federal Open Market Committee is approaching its first meeting under new Chair Kevin Warsh. Rate decisions and forward guidance have been among the most powerful short-term price catalysts for Bitcoin over the past several years, and a new Fed chair introduces a layer of unpredictability that markets haven’t had to price in for a while.

What this means for investors

When 79% of circulating supply is locked up by holders who aren’t selling, the available float for active trading shrinks dramatically. Any meaningful uptick in demand, whether from institutional buyers, retail speculators, or ETF inflows, hits a much thinner order book.

ETF outflows may have slowed to yearly lows, but slowing outflows aren’t the same thing as inflows. The difference between “people stopped selling” and “people started buying” is the difference between a market that stabilizes and one that actually rallies.

A 79% supply concentration among long-term holders, combined with the lowest dormant coin reactivation in 14 years, is not something the market has seen before. The last time reactivation was this low, Bitcoin was trading in single digits.
