The percentage of Bitcoin supply in profit dropping to 45% is a historically important signal, placing us in a zone that has often preceded major upside moves.

A Look at the 45% Threshold

This level is significant because it has coincided with market stress and late-stage corrections in the past . When a large portion of holders are underwater, it suggests a "profitability reset," where weaker hands are flushed out and coins migrate to investors with longer time horizons .

Historical Precedents and Potential Upside

Previous instances of supply in profit entering this zone have been followed by significant rallies. For example, when the metric was around 50-51% in January 2023, Bitcoin traded at roughly $16,682 before eventually rallying 655% to $126,000 in 2025 . A similar setup occurred in March 2020 when supply in profit dropped below 50% and Bitcoin was around $6,500, preceding its move to $69,000 in 2021 . This is why some analysts view this as a potential accumulation zone .

A Key Caveat for This Cycle

However, a crucial difference in this cycle is the behavior of long-term holders. While the overall supply in profit has compressed, the Long-Term Holder Net Unrealized Profit/Loss (LTH-NUPL) remains positive . This divergence is attributed to a growing share of Bitcoin being held by institutions and ETFs, which have a lower sensitivity to short-term price swings and are not selling into weakness . This suggests the market may not see the same level of distress selling from long-term investors as in previous cycles, even as the metric flirts with historical stress levels .

To truly gauge the strength of this signal, it is valuable to pair it with other data, such as exchange net flows and the Spent Output Profit Ratio (SOPR) . These provide additional context on whether the selling pressure is easing.
