aSOPR — Bitcoin Spending Profit/Loss Signal

The adjusted Spent Output Profit Ratio (aSOPR) measures whether Bitcoin being spent on-chain is being sold at a profit or a loss. When the market is in sustained loss-taking (aSOPR < 1), it signals capitulation and historically precedes bottoms.

What It Measures

The average profit ratio of all Bitcoin transactions: (price at time of sale) / (price at time of purchase) for each spent output. Excludes coin-hour-old outputs to filter noise.

How It's Calculated

aSOPR = Σ(realized value) / Σ(value at creation) across all spent outputs in a day, excluding outputs younger than 1 hour, smoothed with a 7-day moving average.

Bottom Signal

Sustained readings below 1.0 — coins are being sold at a loss on average. This capitulation zone, when held for multiple days/weeks, has marked every major cycle bottom.

Historical Readings at Cycle Bottoms
