Bitcoin Long-Term Holder Supply Hits Record High Amid Institutional Accumulation

The long-term holder supply of Bitcoin has reached an all-time high of 16.64 million BTC, according to Coinglass data from July 21. This represents roughly 83% of Bitcoin's total circulating supply, with five out of every six coins in existence having sat untouched for over five months.

The long-term holder metric tracks coins that have been idle for at least 155 days, serving as a proxy for investor conviction. When LTH supply rises, it indicates holders are choosing not to sell, whereas a decline suggests coins are moving to exchanges or new buyers during periods of distribution or panic.

In November 2025, LTH supply plummeted to 14.33 million BTC during a price correction that dragged Bitcoin toward the $80K range. However, since then, holders who bought during the correction or refused to sell have aged their coins past the 155-day threshold, resulting in a net addition of over 2.3 million BTC back into the long-term category in about eight months.

CryptoQuant CEO Ki Young Ju noted that strategic buyers and ETFs have been absorbing Bitcoin from older large holders, with institutions, corporate treasuries, and ETF vehicles stepping in as the new long-term base. This shift has created a structural demand floor that didn't exist in prior cycles.

With 83% of supply effectively off the market, the amount available for active trading shrinks dramatically. Less liquid supply means each incremental buyer has an outsized impact on price, and each seller has less inventory to dump.
