A trading signal that has correctly called every Bitcoin bear-market bottom in history just fired again. Analyst Willy Woo says the Fisher Transform, a classic trend indicator, printed its fourth-ever bullish crossover on the monthly Bitcoin chart — and the previous three all marked the exact end of bear markets, with no fake-outs.

The Hook: A Signal With a Perfect Record
Bitcoin is currently trading near 76,567 after a bruising few months that took the price to multi-month lows over the summer. Now one of crypto’s best-known on-chain analysts says the worst may finally be behind us. Writing on X, Willy Woo pointed to the Fisher Transform — a price trend tool created back in 2002 — and its behavior on the monthly chart. “BTC bottoms: 3 for 3 without fake out,” Woo wrote. “Latest cross is the 4th on record.”
For regular investors, here’s the translation: an indicator that has nailed the bottom of every major Bitcoin crash just turned bullish again. If history rhymes, a new long-term uptrend could be starting.
On-Chain Evidence: How the Fisher Transform Works
The Fisher Transform smooths out Bitcoin’s wild price action into a readable trend-strength chart. Market prices tend to hover near extremes more than normal statistics would — think of how a panic sell-off clusters all the losses into a few dramatic days. The indicator corrects for this with a mathematical adjustment, producing two lines: the Fisher line and a trigger line that follows it with a one-period delay.
When those two lines cross over sharply to the upside on a monthly chart, it has historically coincided with the end of bear markets. The crossover that just happened occurred in July at a reading of -2.26. Each of the three previous monthly crossovers — at past cycle bottoms — was followed by a new macro uptrend, with no false signals mixed in.
Woo explains why bottoms are more reliable than tops in this system. When price falls far enough that long-term investors see genuine value, buying pressure returns — and crucially, the speculators are gone. “Price reverses more cleanly without the choppy fake outs seen in tops,” he said. “Hence bottoms are easier to define.”
The Core Conflict: A Weekly Divergence backs the Monthly Signal
There’s a second layer to the argument. On the weekly chart, the Fisher Transform hit its swing low of -2.85 at the end of December last year, when Bitcoin was still trading around 90,000. Since then, the indicator has been printing higher lows while the price itself made lower lows — a textbook bullish divergence.
In plain terms: the selling pressure behind each new price low has been weakening, even though the headline price kept falling. The same pattern appeared in 2022, during the final six months of the last bear market, right before the recovery that carried Bitcoin to new highs.
Not everyone is convinced. Doubts remain over whether Bitcoin’s 21-month lows near 57,000 on July 1 truly marked the cycle bottom. Woo himself noted last week that typical buyer interest was missing at those lows — the dip was mostly accumulated by a small number of large-volume investors rather than broad demand.
Market Implications: What History Suggests Comes Next
- The monthly Fisher crossover has a 3-for-3 record of marking bear-market bottoms — no false positives on record.
- The July crossover at -2.26 is the fourth on record, forming during the depth of the summer sell-off.
- The weekly bullish divergence mirrors the 2022 pattern that preceded the last recovery.
- Caveat from Woo himself: price could still consolidate or drift lower first, much like bull-market tops produce fake signals before resolving.
Ethereum is changing hands near 2,463 and Solana around 101, both bouncing alongside Bitcoin as markets digest the Federal Reserve’s recent rate path. A genuine macro bottom in Bitcoin would lift the entire digital asset market, from major altcoins to the ETF complex that now channels institutional money into the space.
The key takeaway for the divergence argument: when an indicator improves while price worsens, someone is quietly absorbing the selling. That’s usually not retail panic — it’s patient capital positioning for the next cycle.
The Verdict: Promising, Not Guaranteed
A perfect-record indicator flashing its fourth bottom signal is genuinely notable — but it’s a probabilistic edge, not a promise. Woo himself flagged that price can consolidate or continue lower even after the crossover, since speculative trading activity during recoveries can muddy the signal. Investors should treat this as one data point in a bigger picture that still includes Federal Reserve policy, ETF flows and the slow absorption of supply from long-term holders.
For anyone who has been waiting on the sidelines, the message from this signal is simple: the deepest phase of capitulation may already be behind the market. The bottoms that matter tend to form quietly, while sentiment is still sour — exactly where Bitcoin sits today near 76,567.

fourth signal in the entire chain history is the stat that matters. three for three across completely different macro regimes beats most indicators with daily prints
3 for 3 with zero fakeouts on the monthly is a scary sample to ignore. bought my first whole coin after the 2015 cross, watching this one closely
fisher transform gang rising. if this one fakeouts im deleting my account, screenshot it
Three prior signals is a small sample, but the fact they all landed on exact bear market ends is why people take Woo seriously. Price at 76,567 makes the entry debate interesting.
an indicator from 2002 with n=3 and everyone acts like its a law of physics. still long tho lmao
n=3 is fair criticism, but those three covered very different market structures, spot ETFs did not even exist for two of them.
n=3 but all three landing on the exact end of a bear market is still a better record than my discretionary trading lol. signal + on-chain context is why woo gets the benefit of the doubt
n=3 beating my discretionary trading record too tbh. add woos onchain supply data on top and its less of a coin flip than it looks
calling n=3 a joke on the fisher transform while admitting youre still long is the most crypto comment possible lol
admitting n=3 while staying long is the correct posture honestly. the signal is a reason to size up, not a prophecy
sizing up instead of going full degen on n=3 is the disciplined read. the sample spans 2015 to 2022, three totally different macro regimes, thats what makes it worth respecting
n=3 sure, but those three covered 2015, 2018 and 2022, completely different market structures each time. small sample, varied conditions, still 3 for 3
3 for 3 with no fake-outs is the kind of stat that sounds amazing until you remember the sample size is… three. Still, Woo’s on-chain work has been better than most. Cautiously optimistic here.
fisher transform monthly cross firing at 76.5k while everyone was writing btc obituaries in august. i bought the summer wick and now the signal shows up too, ill take the confirmation
Monthly timeframe crossovers are slow but when they hit they hit. If this one plays out like the last three we look back at 76k as the sale of the cycle.
@chartsloth_ that’s exactly the trap though. Everyone says ‘this time it’s the bottom’ and then we get another leg down to 60k. I’ll believe it when we reclaim 90k.
@Dinu Petrescu fair skepticism, but the previous three crossovers weren’t ‘everyone says bottom’ moments — barely anyone noticed them until after the fact. That’s the difference this time, it’s public. Which, granted, could be the counter-signal lol.
if the monthly cross fails this time it would be the first fakeout on record, which is exactly why the risk reward works here. stop below 70k and let the monthly do its thing
Fisher Transform on the monthly is basically a once-per-cycle signal. Even if the indicator itself is voodoo to me, the fact that it only fires at true exhaustion points is compelling.
@Maeve Traynor it’s not voodoo, it’s just a normalized price transform that highlights turning points. The monthly filter is what makes it rare. Good article finally explaining it without the hype, most coverage was just ‘Woo says bottom’.
Woo called bottoms early in 2022 too and got roasted for months before being right. Time in the market vs timing the signal and all that.
woo being early in 2022 was the signal working, just painfully. monthly crossovers dont come with a delivery date attached
roasted for months is generous, people were posting his drawdown screenshots daily. being early AND loud is a brutal combo, the quiet ones get forgotten instead
Accumulating quietly either way. If it’s the bottom I win big, if it isn’t I DCA lower. The only losing move is sitting out because a chart scared you.
fisher transform on the monthly is a regime indicator, not an entry signal. woo mashing the two together is why the replies are half what price do i buy
signal fired with price near 76.5k after the summer flush to 58k. worst case this is a slow grind higher, best case the fourth cross becomes the bottom everyone quotes in two years
entry near 76.5 with a defined invalidation below the summer flush is decent geometry. the crowd roasting him will fomo his call in six months anyway
worst case a slow grind is doing a LOT of work in that take lol. still, first fakeout on record being the risk you take is decent trade shape at 76.5
76.5 as invalidation is clean. worst case you chop sideways for months, beats every signal that needs a new low to work
