Bitcoin's long-term holder (LTH) supply has risen significantly, reaching 16.3 million BTC, as investors capitalize on current market conditions. This increase of over 2 million BTC during the ongoing bear market reflects a common strategy among long-term holders, who typically buy during price declines and sell during price increases. The LTH supply has grown from 14.12 million BTC when Bitcoin peaked above $126,000 in October, with a notable 200,000 BTC added in the last month alone. The only time the LTH supply was higher was in January 2024, just before the anticipated U.S. spot Bitcoin ETF launch. Following the ETF's introduction, LTH supply fluctuated between 14 million and 16 million BTC, but recent trends indicate a breakout from a 2.5-year downtrend. This suggests that long-term holders are once again accumulating Bitcoin during its current depressed price levels, reminiscent of previous bear markets in 2015 and 2019.
