Finding the Right Time to Buy Bitcoin: Does It Exist?
Is there a right time to buy bitcoin? Every start day since 2011 backtested: when buyers were at a loss and what timing really got them.
Is there a right time to buy bitcoin? You could never recognise it in advance; in hindsight it is always obvious. So far, how long you held mattered more than the day you bought: of all start days since 2011, almost one in three was at a loss after one year, and none after four. A low price near the Power Law floor improved the result clearly, but it was not a signal you can wait for.
Almost everyone who thinks about bitcoin asks the same question: do I buy now, or do I wait for a better price? This article answers it not with opinions but with every daily close since July 2010. Whether you should invest an amount all at once or spread it out is a separate question, answered in Savings plan or lump sum.
Why the question weighs so heavily
Bitcoin swings hard. Since 2014, the highest close of a year was usually two to six times the lowest, in 2017 even 25 times. Buy on the wrong day and you quickly see a 50% loss in your account. No wonder many people wait. But waiting is a decision too, and it has its own price.
The calculation below takes every day since 1 January 2011 as a possible start day. For each one, it looks at where the price stood one, two, four and eight years later. It is calculated in US dollars with the site's daily data up to 7 November 2026.
How often were buyers at a loss?
| Holding period | Start days | of which at a loss | Median return | Worst start day |
|---|---|---|---|---|
| 1 year | 5’425 | 28.8% | +89% | −84% (16 Dec 2017) |
| 2 years | 5’060 | 16.2% | +245% | −68% (4 Dec 2013) |
| 4 years | 4’329 | 0% | +1’227% | +31% (8 Apr 2021) |
| 8 years | 2’868 | 0% | +10’882% | +347% (16 Dec 2017) |
After one year, the result is almost a loaded coin toss: a good two thirds of start days were ahead, just under a third behind, and the losses were deep. After four years, not a single start day was at a loss. Three years were almost always enough too: only 33 of 4’694 start days were at a loss after three years, all around the 2013 top (November 2013 to January 2014) and in February 2021.
The early years with their extreme returns distort the medians. Counting from 2015, the pattern stays the same: 27.6% loss days after one year, 17.4% after two, 0% after four and eight years. Only the medians are smaller, +75% after one year and +447% after four.
How it is calculated
Return = close on the same calendar day n years later ÷ close on the start day − 1
Start days: every day from 1 Jan 2011 for which the price n years later is already known (last close 7 Nov 2026). If the end date falls on 29 February, the 28th is used.
Example, worst start day over 8 years: 16 Dec 2017 at $19’640.51 → 16 Dec 2025 at $87’863 → 87’863 ÷ 19’640.51 − 1 = +347%
Example, worst start day over 4 years: 8 Apr 2021 at $58’091 → 8 Apr 2025 at $76’330 → +31%
Best against worst day in each year
How much did the day within a year matter? The table shows each year's lowest and highest close and what buying exactly there would have returned after four years.
| Year | Lowest close | after 4 years | Highest close | after 4 years |
|---|---|---|---|---|
| 2014 | $310 (30 Dec) | +1’125% | $914 (6 Jan) | +1’770% |
| 2015 | $176 (14 Jan) | +1’964% | $465 (15 Dec) | +1’432% |
| 2016 | $366 (31 Jan) | +2’453% | $980 (28 Dec) | +2’663% |
| 2017 | $788 (11 Jan) | +4’391% | $19’641 (16 Dec) | +143% |
| 2018 | $3’212 (15 Dec) | +440% | $17’104 (6 Jan) | +152% |
| 2019 | $3’398 (7 Feb) | +584% | $13’090 (26 Jun) | +131% |
| 2020 | $4’797 (12 Mar) | +1’389% | $28’918 (31 Dec) | +224% |
| 2021 | $29’341 (1 Jan) | +222% | $67’525 (8 Nov) | +52% |
Two things stand out. First: in every year, even the worst day was ahead after four years. Second: the best day of the year was not always the best start. In 2014 and 2016, buying at the year's high did better over four years than buying at its low, because the end date four years later happened to fall into a boom. The end of a calculation is also a point in time nobody chooses.
In boom years, the gap between the best and the worst day was huge: in 2017, the result of the two starts after four years differed by a factor of 18. In quiet years like 2015 and 2016 it was small.
Perfect timer, worst timer, savings plan
Now the comparison that answers the question most directly. Three investors put €1’200 into bitcoin each year:
- The perfect timer buys once a year, €1’200, on the day with the lowest euro price.
- The worst timer buys once a year, €1’200, on the day with the highest euro price.
- The saver buys €100 on the 1st of every month without thinking about it.
Everything is valued at the price of 7 November 2026, $75’868 or about €67’730.
| Period | Paid in | Perfect timer | Saver | Worst timer |
|---|---|---|---|---|
| 2014–2025 | €14’400 | 19.30 BTC = €1’307’049 | 12.21 BTC = €827’249 | 6.30 BTC = €426’635 |
| 2018–2025 | €9’600 | 1.359 BTC = €92’069 | 0.721 BTC = €48’798 | 0.340 BTC = €23’057 |
| 2022–2025 | €4’800 | 0.206 BTC = €13’955 | 0.131 BTC = €8’848 | 0.081 BTC = €5’454 |
Over shorter periods the picture is the same: the saver always lands between the two extremes, 37 to 47% behind the perfect timer. The biggest difference was not the day, but whether someone bought and held at all.
How it is calculated
Euro price of a day = close in $ ÷ the month's euro rate (USD per EUR); for November 2026 the October rate of 1.1202.
Perfect timer: bitcoin = sum over the years of €1’200 ÷ the year's lowest euro price
Worst timer: the same with the year's highest euro price
Saver: sum over all months of €100 ÷ euro price on the 1st of the month
Value = bitcoin × $75’868 ÷ 1.1202 = bitcoin × €67’730
Before fees and taxes. A savings plan's fees depend on the provider and reduce its result by a few percent.
Did buying near the floor help?
The day cannot be predicted. But whether bitcoin is cheap or expensive relative to its long-term trend can be measured. The site uses the Power Law model and its floor for this, a rising line below which bitcoin has closed on only a few days so far. So the next question: were purchases near the floor better?
The table sorts all start days since 2015 by the multiple of the floor the price stood at on the start day. The early years are left out because their extreme returns would inflate every group.
| Price on start day | Start days | at a loss after 1 year | Median after 1 year | Median after 4 years | Worst after 4 years |
|---|---|---|---|---|---|
| below the floor | 79 | 0% | +156% | +4’086% | +1’982% |
| 1 to 1.5 × | 1’500 | 0% | +145% | +1’829% | +194% |
| 1.5 to 2 × | 797 | under 1% | +130% | +500% | +139% |
| 2 to 3 × | 966 | 42% | +19% | +291% | +94% |
| above 3 × | 987 | 70% | −31% | +189% | +31% |
The relationship is clear: the closer to the floor, the better the result, after one year as after four. Those who bought above three times the floor were mostly at a loss after one year. Those who bought near the floor never were.
Three caveats belong with it:
- The groups differ in size. Since 2015, the price was below the floor on only 79 days. The four-year figures of that group come almost entirely from 2015. That is a single cycle.
- Cheap can hurt too. Someone who bought in April 2025 at just under twice the floor was up to 12% down a year later. On 30 June 2026, bitcoin even closed slightly below the floor. Cheap never meant "only up from here".
- Expensive was still ahead after four years. Even purchases above three times the floor stood at least 31% higher four years later. Those who waited for years because of a high valuation often missed more than a bad entry would have cost.
How the floor is calculated
Power law in $ = 10^−16.493 × days^5.688, days since the genesis block on 3 Jan 2009
Floor = 0.42 × power law
Multiple of the floor = close on the start day ÷ floor on the start day
7 Nov 2026: floor $66’766, price $75’868 → 75’868 ÷ 66’766 = 1.14 ×
The groups by multiple of the floor are not the same as the valuation zones: their upper bounds fall over the years with the top band. All figures follow the methodology.
Time in the market, zones as a guide
What does this mean for you? The data argue for a simple stance.
Time in the market beats timing. So far, everyone who held for four years came out ahead, no matter which day they bought. The question "today or next month?" mattered far less than the question "will I hold on?". How to sit through a 50% crash without selling is therefore the more important preparation. HODL psychology helps with that.
The zones say how much, not when. The bitcoin valuation zones show whether the price is cheap or expensive relative to the trend. Use them to adjust the size of your purchases: more in floor and accumulation, less or nothing extra in hot and euphoria. They are not a signal to get in. The price can stay at the floor for months, and in euphoria nobody knows how long the party lasts.
A plan beats gut feeling. Decide in advance what you do in which zone, and stick to it. What such a plan looks like in a downturn, with rules for the savings rate and a reserve, is in Buying bitcoin in a bear market.
Where the zones lie today and which one bitcoin is in right now:
On 7 November 2026, bitcoin stood at 1.14 times the floor, in the accumulation zone. Historically that was a good area to buy. Whether the price rises from here or first falls below the floor once more, no model can tell you.
Frequently asked questions
Is there a perfect time to buy bitcoin?
In hindsight yes, in advance no. The lowest price of a year is only known once the year is over. Buying every month got 53 to 63% of a perfect timer's result so far, without any guessing.
How long do I have to hold bitcoin to avoid a loss?
So far, four years were enough: no start day since 2011 was at a loss after four years. After one year it was 29%, after two years 16%. That is history, not a guarantee for the future.
Should I wait for a crash before buying?
Waiting usually cost more than it gained. Even purchases at the worst moment were ahead after four years. If you are unsure, start a savings plan and buy extra when the price falls into a cheap zone.
Is now a good time to buy bitcoin?
On 7 November 2026, bitcoin stood at 1.14 times the floor, in the accumulation zone. Since 2015, purchases in this range did well after one and after four years. How it goes this time, nobody knows.
What is better: timing or a savings plan?
For almost everyone, the savings plan. It takes the decision off your hands and reliably lands between the best and the worst timer. Buying more or less according to the zones on top of it uses the valuation without betting on a day.
