SOPR — Spent Output Profit Ratio
SOPR measures whether on-chain-moved Bitcoin are sold at profit or loss today. Below 1 indicates capitulation — historically often direct bottom signals. Renato Shirakashi (Unchained, 2019) invented the indicator; STH/LTH variants split by holding duration.
- Formula:
- Realized Value (USD at sale) ÷ Value at Creation (USD at buy)
- Originator:
- Renato Shirakashi (Unchained, 2019)
