What Does SOPR Falling Below 1 Usually Indicate?
When SOPR drops below 1, it means that, on average, the coins moving on-chain are at a loss—holders are selling or transferring assets at prices lower than their initial purchase price. This is usually seen as a signal of bearish or even panicked market sentiment, and under certain conditions it may also point to a local bottom formation.
What SOPR Actually Measures
SOPR (Spent Output Profit Ratio) is an on-chain indicator that measures whether a coin, at the moment it is moved, is being sold at a profit or a loss relative to its buy price.
The formula is:
SOPR = Sell Value / Buy Value
Breaking it down:
SOPR > 1: On average, moved coins are in profit. Holders are selling at a gain.
SOPR = 1: On average, coins are moved at break-even.
SOPR < 1: On average, moved coins are at a loss. Holders are selling or transferring at a loss.
A concrete example: You bought 1 BTC for $20,000 and later sold it for $30,000. The SOPR for that transaction is 30,000 / 20,000 = 1.5, meaning you made a profit. Conversely, if you sold at $18,000, the SOPR would be 0.9, meaning you took a loss.
Prerequisite: Checking SOPR data requires no wallet interaction. Simply visit on-chain data platforms such as Glassnode, CryptoQuant, or OKLink.
What SOPR Falling Below 1.0 Typically Means
When SOPR falls below 1.0, the core message is: loss-making selling is taking place in the market.
Depending on the market phase, it may correspond to the following scenarios:
Scenario A: Panic Selling (most common interpretation)
A persistently sub-1 SOPR indicates that a large number of investors are choosing to "cut their losses" and exit, selling coins even at a loss. This typically occurs in the middle to late stages of a market decline and represents spreading fear. This often corresponds to "market capitulation" or panic selling.
Scenario B: Sign of a Price Bottom Forming (under specific conditions)
This may sound counterintuitive, but SOPR falling below 1 is not always entirely bad. When the SOPR for short-term holders (coins held for less than 3 months) keeps dropping and even falls below around 0.9, it usually means that weak hands have been flushed out and selling pressure is nearly exhausted. A local bottom may be forming.
Scenario C: Cycle Transition Signal
Using the 180-day moving average of SOPR (aSOPR 180D) as an observation tool, a pattern emerges: when this moving average persistently falls from a high level and dips below 1, it often marks that the market has entered a bearish phase. In other words, this serves as an auxiliary signal for identifying a transition between bull and bear cycles.
An Important Practical Note: Not All On-Chain Moves Are "Sells"
A common limitation of SOPR is that it cannot distinguish whether an on-chain transfer is an actual sale to someone else or merely an internal transfer between wallets. If you simply move coins from a cold wallet to a hot wallet, that movement will still be counted as a "spent output" in SOPR.
This is why the industry often uses aSOPR (adjusted SOPR), which filters out some extremely short-lived "noise" transactions (typically those with a lifespan of less than 1 hour), allowing the data to reflect genuine market behavior more accurately.
Risk Warning: SOPR is a lagging indicator. It reflects buying and selling behavior that has already occurred and cannot directly predict future price movements. Making trading decisions based on a single indicator carries significant risk. It is advisable to cross-validate with other metrics such as MVRV, exchange inflows, and funding rates.
After the above analysis, how can you confirm your understanding?
Find the BTC SOPR chart on Glassnode or CryptoQuant and check the values over the past 7 days—if it has been consistently below 1, it indicates the market is currently in a loss-selling state; if it has already dipped below 0.9, observe whether the price is showing signs of stabilization. This serves as a reference thought process for assessing whether a bottom may be approaching.
