Binance Research puts bitcoin's 47% rebound in a group of rallies that failed four times in five
Binance Research says four of five past bitcoin rallies that started this far below the prior high later broke their cycle lows. A repeat from CoinGecko's latest $85,988 price would mean a fall of nearly 33%, to below July's $57,800.

What happened
- Binance dates the current signal to Sept. 3, when bitcoin sat 35.6% below its prior high, inside the 30% to 38% band of the five shallow cases.
- The two deep-drawdown signals, April 2019 at 75.5% below the high and January 2023 at 67.1%, both went on to new highs without a new low.
- July 2021 is the only shallow case in the study where the rebound held without bitcoin making a new low.
- Bitcoin followed the failing pattern earlier this year, when a 38% recovery from the $60,000 February low ended with that low breaking on June 5.

Why it matters
- contradiction Binance's two findings pull against each other: the rebound study files this signal as shallow, while the volatility study puts the bear market behind it close to the severity of the last three.
- constraint The next outcome alone moves the shallow group's hold rate from 20% to either 17% or 33%, a spread too wide to anchor a position-sizing rule.
- decision Allocators adding exposure on October seasonality are weighing a 12.7% median return that Binance says guarantees nothing against a one-in-five hold rate in comparable rallies.
Binance's Oct. 5 weekly report measured the rally to an Oct. 1 close of $84,880 [1], but the signal it tests fired a month earlier. Forty percent above $57,800 is $80,920, and 35.6% below the $126,200 peak is about $81,300, so the Sept. 3 trigger came in about $350 above the threshold [1]. The study covers every case from 2011 to 2023 in which bitcoin closed at least 40% above its cycle low while still at least 25% below its previous all-time high [3]. There are seven, and three held while four broke [2]. Binance called the result a "base rate rather than a forecast" and said seven episodes are too few for a reliable forecasting model [8].
The strongest argument against the study's own sorting is in the same report. The groups are defined by raw percentages, and Binance's volatility work shows those percentages shrinking as annualized volatility fell from 99% in 2013-2015 to 87%, then 67%, then roughly 47% in this cycle [11]. Adjusted for that, the 54.2% fall from $126,200 to $57,800 is 1.94 standard deviations, against 1.93, 2.11 and 2.20 for the 86.9%, 84.1% and 77.6% bear markets before it [10][12]. Binance equates today's decline with an 80.8% fall at 2013-2015 volatility [13]. That figure matches scaling the log decline by the ratio of volatilities: ln(0.458) is about -0.78, times 99/47 is about -1.64, which is an 80.7% fall [3]. Put the 35.6% signal reading through the same conversion and it becomes about 47% below the high at 67% volatility, or 60% at 99% [4]. Both numbers land between the 30% to 38% shallow band and the 67.1% to 75.5% deep cases, a range where the study has no observations [5][7][4].
Binance does not take that step. It takes the volatility data as evidence that bitcoin has become less volatile, and not necessarily that it has a stronger price floor [14].
If the base rate holds, the July low breaks soon: the four shallow failures all broke within 43 days, and 43 days from Sept. 3 is Oct. 16 [5][5]. A repeat of July 2021 would mean the rally holds without a new low [6]. The third outcome follows the volatility argument and puts this signal with April 2019 and January 2023, both of which reached new highs without first breaking their lows [7].
This year has already played out the first version once. Bitcoin hit $60,000 on Feb. 6 and recovered 38% by May, to roughly $82,800, before the February low broke on June 5 and the slide ended at $57,800 on July 1 [9][6]. CoinGecko's latest $85,988 is about 4% above that failed peak [4][7].
I think the one-in-five base rate is the right default for sizing, and its weak point is how the signal gets assigned to a group. That assignment uses percentages that Binance's own volatility work says lower volatility has compressed [11][4]. The counter-thesis is that the conversion of the signal reading is not in the report, and Binance itself declines to treat a calmer market as a firmer floor [14]. The view is wrong if Oct. 16 passes with bitcoin still above $57,800 [5][1].
What to watch
- The October rate decision, after September jobs data lowered expectations of a hike, as the main input that sits outside Binance's historical sample.
- Any rerun of the rebound study on volatility-adjusted drawdowns, the test that would show whether the Sept. 3 signal belongs with the shallow failures or with the deep cases that held.
