On September 11, a chain-analytics note landed in my feed with a headline number that did exactly what a good hook is supposed to do: it stopped the scroll. Bitcoin's Supply in Profit — the share of all coins whose last on-chain move priced below today's market — had climbed to 69%, the analyst wrote. The same note claimed a 90-day change of 41%, a price near $77,000, and a rally it described as "mechanical repricing" driven by short liquidations.
I read it twice. Then I did the arithmetic.
69 minus 41 equals 28. If that "41%" is a relative figure, the math collapses entirely — 28 times 1.41 lands near 39.5, nowhere close to 69. So the only internally consistent reading is 41 absolute percentage points: roughly 28% of supply in profit ninety days ago, 69% today. That reframes the entire story. A drop to 28% is not a normal cooling-off; it is a textbook capitulation print, the kind you see at cycle floors and almost nowhere else. And a violent snap from 28 to 69 in a single quarter is a squeeze, not a trend.
Keep that frame. Because everything interesting about this note lives in what it leaves on the table. The signal is real. The conclusion isn't, and the gap between them is where the risk lives.
This isn't a project story. There is no token, no team, no unlock schedule. Bitcoin has none of those, which is precisely why the usual due-diligence playbook — vesting cliffs, VC allocation, the sector's hype cycles — simply doesn't apply here. What applies is methodology.
Supply in Profit walks the entire UTXO set. For every unspent output it takes the price at the moment that output last moved — its cost basis — and compares it to spot. Coins whose cost basis sits below spot are counted as "in profit." The ratio is that count over total supply. It belongs to the same family as MVRV, NUPL, and Realized Price, all of which Glassnode and CryptoQuant publish in both standard and adjusted variants.
Two properties matter, and neither is optional. First, it is a lagging-to-coincident metric. It describes a state; it does not predict a move. Second, the causal arrow runs price to indicator, never indicator to price. When price rises, more coins flip into profit as a mechanical consequence. Reading SIP as a leading signal is a category error, and it is one of the most common mistakes in retail on-chain interpretation.
I have been deconstructing datasets like this since 2017, when I built a ranking filter for ICO whitepapers and found that 60% of more than 200 of them were recycled tech jargon with no utility. The lesson from that exercise never left me: narrative coherence is not evidence, and a clean-looking chart is not a data source. The single most important question to ask of any on-chain note is not "what does it say" but "which provider, which variant, which window." Methodology transparency is the whole game. This note does not disclose its data source, its adjusted-versus-raw choice, or its lookback definition. On adjusted variants the divergence can run five to fifteen percentage points. That is the difference between a capitulation floor and a routine pullback.
So we have a number we cannot fully verify, describing a state we can partly reconstruct, attached to a conclusion we can test. Let's test it.
The mechanism the analyst invokes is real and well-documented. Overcrowded shorts — negative funding, elevated open interest — sit in a fragile stack. A rising price triggers forced short liquidations, and liquidations are market buys. That buy flow pushes price higher, triggering the next liquidation tier in a feedback loop. Short inventory eventually exhausts, the marginal buyer disappears, and a momentum vacuum opens. Price retraces a portion of the move.
We have seen this shape repeatedly: January 2023, August 2024, April 2025. The logic is sound. Short squeezes are, in effect, a self-extinguishing engine. They borrow demand from the future and pay for it with volatility now. When the fuel runs out, the price doesn't need a reason to drift — it simply runs out of bids.
But here is the problem. To claim a squeeze is driving price, you must show the squeeze. This note shows none of it.
Validating a short squeeze requires derivative-side evidence: funding rates flipping negative, open interest collapsing as positions close, liquidation clusters, long/short account ratios touching extremes. None appear. Not one. The note substitutes the phrase "mechanical repricing" for the data that would prove it. That is not analysis. That is a description wearing the costume of analysis.
I have spent enough time around trading desks to know what this looks like from the inside. During my DeFi Summer stint at a fintech newsletter, I wrote a mechanics guide comparing Aave and Compound yields, and the thing I kept flagging to readers was that every APY number hides a subsidy structure. The same discipline applies here. A rally described as "mechanical" is a claim about market microstructure. You cannot verify microstructure without microstructure data.
Now flip to what the note actually does establish, even if it never says so plainly.
If SIP ran from roughly 28% to 69% in ninety days, then 31% of supply sits underwater — coins whose cost basis is above spot. Some analysts frame this as upside fuel. I frame it the opposite way. Those coins are a supply wall. As price rises toward their breakeven, holders who bought higher have a genuine, rational incentive to exit at par — to get their money back. That behavior is not panic; it is discipline. And it caps rallies far more reliably than it fuels them.
Consider the price constraint. The note puts spot near $77,000. If 31% of supply is still in loss at that level, then an enormous quantity of coins changed hands well above $77,000. That is not a market just coming off a floor. That is a market working through a heavy, recent, higher-cost overhang. The 28% floor number and the $77,000 spot number do not sit comfortably in the same picture — one implies deep capitulation, the other implies a congested distribution zone right overhead. The note wants us to feel the first and ignore the second.
Which brings me to the cleanest point in the whole dataset, and the one the note under-develops: momentum decay and price correction are different claims with different confidence levels.
Momentum decay — the rate of change slowing — is a high-confidence read from the SIP structure alone. As profit supply expands, the marginal holder content to sit still shrinks and the marginal seller near breakeven grows. The rate of the rally naturally flattens. That is a strong inference.
Price correction — the level actually falling — is a separate and much weaker claim. It requires additional conditions: macro liquidity tightening, ETF net outflows, or miner distribution. The note provides none of these and still bridges the two as if they were one. That bridge, from "the rally slows" to "the price drops," is the single largest logical gap in the report, and it is the gap a leveraged reader is most likely to fall through.
Here is where the analysis has to zoom out, and where the note's real limitation becomes visible.
Bitcoin sits at the bottom of the crypto stack — settlement layer, reserve asset, the pricing anchor for everything above it. It is depended upon far more than it depends on anything. Its own price, though, is set largely by factors off the chain: macro liquidity, real rates, risk appetite, and — since the ETF era — spot creation and redemption flows. When BlackRock's IBIT prints a net inflow week, that is a rigid, non-discretionary bid arriving independent of any holder's cost basis.
The supply table tells the story cleanly. Issuance runs about 3.125 BTC per block post-halving, roughly 0.85% annualized, dropping toward 0.4% in 2028. The supply side is rigid and predictable. It cannot manufacture selling pressure. Lost coins, estimated in the three to six million BTC range, systematically bias SIP itself. Long-term holders, sitting on low cost bases, tend to absorb rather than distribute. Which means any real selling pressure has to come from demand-side holders — concentrated, in all likelihood, among short-term, high-cost buyers.
Using on-chain supply structure to forecast Bitcoin's price is using an endogenous variable to explain an exogenously driven asset. The tool and the target don't match.
This has gotten worse, not better, post-ETF. A large share of BTC now sits in custody accounts that barely move. That supply is inert. SIP is effectively blind to it. Each year the ETF wrapper grows, the marginal information content of classic on-chain supply metrics shrinks. The metric isn't wrong. It has simply been structurally diluted — and the note treats it as if nothing changed since 2021. A version of this data that hasn't yet hit mainstream media is one thing; a version that's quietly losing its signal is another.
The transmission map completes the picture. Macro liquidity flows into BTC. ETF flows arrive as a rigid bid that can absorb SIP's supply wall. Miners add a post-halving cost squeeze the note never mentions, one that can amplify selling on any dip. Then BTC transmits outward to everything below. A 10% BTC pullback routinely becomes a 15% to 25% drawdown in altcoins, and a 15% BTC move starts triggering DeFi liquidations as collateral marks down.
Which points somewhere the note didn't go. If the momentum-decay thesis is right, the trade isn't in Bitcoin. It's in what Bitcoin drags down. Bitcoin's beta is close to one; the assets it collateralizes carry betas of 1.5 to 2.5. The asymmetry isn't in the anchor. It's in the chain above it. Not mentioning this costs the note most of its practical value.
Let me name what this document actually is, because the framing matters more than the content.
This is an opinion piece. Not an event. There is no ETF approval, no exploit, no protocol upgrade, no regulatory ruling. It is one analyst's read of one metric. Opinion content has a half-life of 24 to 72 hours, and it has no directional force of its own. It can nudge sentiment; it cannot move capital. Treating a "momentum may fade" note as a tradable signal is the mistake, and it is a costly one.
The market-side checklist makes this concrete. Seven indicators would matter for validating the note's core claim: stablecoin net inflows, exchange net flows, futures open interest, funding rate, the Fear & Greed index, ETF net creations and redemptions, and liquidation data. All seven are missing. The squeeze thesis rests on the one category of evidence the note declines to provide. So we cap the conclusion at "reasonable speculation" and we say so plainly. A protocol's launch strategy and community management can be judged from its own telemetry; a market thesis has to be judged the same way, from its own inputs. This thesis arrives with empty hands.
There is a timing problem too. Notes like this typically travel a specific path: an analyst posts on a platform like CryptoQuant, an aggregator picks it up, media re-shares it days or weeks later. For a claim whose entire value is timeliness — "momentum is fading right now" — that latency can erase the point before a reader ever sees it. A diagnosis that arrives after the patient has recovered is not a diagnosis.
And the audience reveals the intent. "Short squeeze" is leverage-trader language. The note is written for people holding positions with liquidation prices, not for allocators building multi-year exposure. That's fine, as long as the reader knows which room they are standing in.
Strip the note down and one usable signal remains: when profit supply expands this fast from a capitulation base, the rally's rate of change tends to decay. That is worth holding. It is not a reason to short Bitcoin.
The confirmation set is specific, and none of it requires an on-chain subscription. Watch funding rates for a sustained negative print. Watch open interest for a sharp drop — that is the squeeze exhausting. Watch ETF flow for a flip to net redemptions, the only demand-side force large enough to overwhelm a supply wall. Watch miner wallets for distribution. If two or three of those align, the pullback case stops being speculation and becomes structural.
If they don't, the more likely outcome is a 5% to 15% technical retrace — not a trend reversal — and the deeper pain sits in altcoins and DeFi collateral, not in the asset at the center of the note.
In a bear market, the question is never how much I can make. It is which of my assumptions is load-bearing and which is decoration. This note's headline is decoration. The arithmetic underneath it — and the data it quietly omits — is load-bearing.
