With October 1 the same word comes back every year: Uptober, the claim that October is the reliably strong month in the crypto market and the fourth quarter the strong season. We ran the numbers for the four largest tradable coins over nine years, in each case from the September 30 close to the December 31 close, and additionally for October on its own. The result splits in two. For Bitcoin the claim does hold up in October, with seven of nine years in the black. For the full quarter it barely holds, and for XRP it does not hold at all.
This calculation is not a forecast. What has been counted is how often something happened in the past and, above all, how far the individual years lie apart. Base a decision on a season and you are basing it on an average that never arrived in any single year.
Behind the word sits a seasonality thesis: certain months deliver better returns on average than others, because capital flows, tax deadlines and expectations repeat over the course of the year. Seasonality in statistics means that a time-series value depends systematically on the calendar and not only on chance.
Two measures make that testable, and the order matters. The first is the hit rate: in how many years did the period end in the black? The second is the median, the value in the middle of all years. The median says more here than the average, because a single extreme year shifts the average at will while leaving the median alone. That is exactly what happens regularly in the crypto market, and further down you will see how strongly.
For October on its own, the picture at Bitcoin is as clear as the word promises. From 2017 to 2025 the month closed higher than it opened seven times; only 2018 and 2025 ended in the red. The median sits at plus 10.9 percent.
Seven out of nine is a rate nobody can argue away. What it is not is a guarantee for the tenth case. Two losing years in nine means that on average every fourth or fifth October runs against the thesis, and the most recent one did.
Here the picture tips. Measure not to October 31 but to December 31, and only five of nine years at Bitcoin remain in the black, with the median shrinking from plus 10.9 to plus 5.4 percent. In plain terms: what October often brought in, November and December frequently took back.
Anyone who aligns a decision with the quarter rather than the month therefore faces a coin-flip rate historically, with a slight tilt to the upside. Which dates are actually due in the current quarter we have put together in our overview of crypto dates for the fourth quarter.
October and the year-end often ran in different directions over the past nine years: the month carried the season, the quarter did not.
The arithmetic average of the nine Bitcoin quarters stands at plus 44.7 percent. That figure appears in many seasonality tables, and as an expected value for a coming quarter it is worthless. It comes almost entirely out of two years: 2017 with plus 219.5 percent and 2020 with plus 168.9 percent. Take those two out and an average of roughly plus 2 percent over seven years remains.
Both exceptional years followed a halving of the Bitcoin reward, in 2016 and 2020, and fell into phases of strong inflows. A season that draws its statistics from two special years describes those special years, not the calendar. The median of plus 5.4 percent is the more honest figure, and it is unspectacular.
At Ethereum you can see how little a hit rate is worth on its own. Six of nine Octobers closed in the black, so the rate sounds good. The median, however, is just plus 0.7 percent, because the winning months were mostly narrow and the losing months clear: minus 15.2 percent in October 2018, minus 7.2 in October 2025, against plus 0.6 and plus 0.7 percent in two of the winning years.
Over the full quarter the relationship reverses: five of nine years in the black, but a median of plus 22.5 percent, the highest of the four coins. Ethereum delivered less often in the fourth quarter, yet more powerfully when it did. How the two largest coins stand against each other this quarter we have broken down in our direct comparison of Bitcoin and Ethereum.
At XRP the Uptober thesis does not hold. In October only three of nine years ended in the black, and the median is negative at minus 0.9 percent. Over the full fourth quarter it is likewise three of nine, with the median falling to minus 12.9 percent. Six of the nine quarters ended in the red, four of them consecutively from 2019 to 2022.
The average says something altogether different here, namely plus 111.9 percent, and that shows the trap in its purest form: it stems practically alone from the fourth quarter of 2017 with plus 899.5 percent and from 2024 with plus 240.1 percent. Reckon on seasonal strength for XRP and you are reckoning with two years against six.
Solana has been quoted continuously on the major venues only since 2021, so the series covers just five fourth quarters. Three of them ended in the black. The spread makes any averaging questionable: plus 376.1 percent in the fourth quarter of 2023 stands against minus 70.0 percent in the fourth quarter of 2022, the quarter of the FTX collapse.
Five observations are statistically too few for a seasonal statement. That is no criticism of the coin but a limit of the data. With a coin of short history, a quarterly statistic mainly describes the major events that fell into those quarters.
A seasonal statistic describes the average of many years, not the year in which you happen to be at the helm.
The most recently completed fourth quarter ran against the thesis at all four coins, and clearly so: Bitcoin minus 23.3 percent, Ethereum minus 28.4, Solana minus 40.4, XRP minus 35.4. October 2025 itself was negative at all four as well.
That does not refute a seasonality; a single year never can. It does place it, though: the most recent case, the one everybody still remembers, is the counter-example to the slogan. When you read in October 2026 that October is historically strong, last October lies in between, and it was not.
On October 3 Bitcoin stands at around $84,900, Ethereum at about $2,684, Solana at roughly $120 and XRP at about $1.49. Against September 30, barely anything has moved in the first days of the quarter: Bitcoin is a good 1.6 percent higher, Solana around 1.5 percent, Ethereum and XRP practically unchanged.
For comparison: in the strong Octobers of 2017 and 2021, Bitcoin was clearly ahead after the first trading days already. A quiet start says nothing in itself about how the month ends, but it does show that the season does not switch on automatically just because a date has been reached. The current prices of the individual markets you will find directly at the venues, for instance in the XRP market at Bitstamp.
Nine observations are a small sample. With a hit rate of seven to two, nine cases do not cleanly separate whether a calendar effect sits behind it or a clustering of the kind chance produces regularly in short series. On top of that, the nine years are not independent of one another, because all nine lie within two market cycles, and inside a cycle the quarters run alike.
In practice that means a seasonal statistic is an argument for humility, not for timing. A statistic of this kind is good for dampening an expectation that arises from a slogan. For justifying a purchase date it is not. Anyone buying regularly and in fixed amounts sidesteps the question entirely; what that looks like in practice is shown by our comparison of savings plan providers.
For investors in Germany the fourth quarter carries a second, very concrete calendar layer, and it has nothing to do with seasonality. Under Section 23 of the German Income Tax Act, cryptocurrencies held as private assets fall under a one-year holding period: sell at a profit within a year of buying and that profit is taxed at your personal rate. Once the year is up it is tax-free. For gains inside the period an exemption limit of 1,000 euros a year applies, covering all private disposal transactions together; exceed it and the entire amount becomes taxable.
From that follows a calculation that beats any seasonal consideration: if your purchase date falls in December of the previous year, a sale a few weeks before the anniversary can cost more than any price move you avoid by it. Conversely, losses inside the period can be offset against gains from other private disposal transactions of the same year. For your own case a tax adviser is the right address, not a calendar saying.
