Bitcoin traders' unrealized profit margins, which measure paper gains not yet locked in, climbed to 33%, their highest level since December 2024, CryptoQuant said. The increase followed a rally that took Bitcoin to an eight-month high of $87,400, prompting the analytics firm to warn that a correction could be near. Bitcoin holders realized profits on 25,700 BTC on Sept. 22, an amount described in The Block's report as the largest, without a specified comparison.
