Bitcoin holders' Net Unrealized Profit/Loss (NUPL) indicator surged from 0.09 to 0.36 last quarter, according to a report by Fidelity Digital Assets. The sharp increase reflects growing unrealized profits among Bitcoin investors over the recent period. Historically, when the NUPL indicator reaches approximately 0.36 (±0.05), Bitcoin's median return over the following year has often reached 93%, per Fidelity's analysis.
