Cycles, without the prophecy
How long does a crypto bear market last?
The four-year cycle
The crypto market cycle is Bitcoin's roughly four-year rhythm: about three years up, about one year down. That pattern is worth knowing. So is the reason it might not repeat... and how to build a plan that doesn't need it to.
What is the crypto market cycle?
The crypto market cycle is the closest thing crypto has to a seasons calendar. And like the weather, it doesn't always show up on schedule.
The market cycle is the repeating sequence of expansion, peak, contraction and bottom that crypto has moved through several times. For Bitcoin it has historically lasted about four years: a long rally of roughly three years, then a decline of roughly one year that took about 84% off the peak in 2017 to 2018 and about 77% in 2021 to 2022. The cycles have lined up closely with Bitcoin's halvings, the scheduled cuts in new supply that happened in 2012, 2016, 2020 and 2024.
So who's this for? The person who wants context for their decisions. If you're looking for someone to hand you the exact date of the next top, there are plenty of crypto YouTubers happy to do it. We're not one of them.
We treat the cycle as context, not a forecast. It tells you what kind of market you might be in. It doesn't tell you what happens next week.
How have past Bitcoin cycles played out?
Same shape, twice.
- 2017 to 2018. Bitcoin peaked near $20,000 in December 2017, then fell for about a year to a low near $3,200 in December 2018.
- 2018 to 2022. From that low it rallied for roughly three years to a peak near $69,000 in November 2021, then fell for about a year to a low near $15,500 in November 2022.
On my own monthly chart, I measure the legs at 427 days down from the 2017 high, about 1,000 days up, and 395 days down from the 2021 high. And I'll be straight about the limits: "We only have this one cycle right here to compare this to." The earlier cycles were small, thin markets. Two clean examples? That's a pattern worth respecting. It's not a law of physics.
Will this cycle be different?
Here are the arguments we take seriously, on both sides. The first three say the cycle fades. The last three say it sticks around. Our view follows.
Institutional money
Spot Bitcoin ETFs and corporate treasuries bring steady flows that didn't exist in earlier cycles. This isn't just retail enthusiasm anymore.
Regulation and custody
Clearer rules and institutional custody make it easier for big, slow money to hold through downturns instead of vanishing.
Government involvement
Governments and states discussing or building strategic reserves are a new kind of holder, with a very different time horizon.
Human psychology
Greed and fear have driven bubbles from tulips to tech stocks. New buyers don't make people behave any differently at the top.
Leverage
Heavy leverage keeps producing sudden liquidation cascades that wipe out rallies, no matter who else is in the market.
Global liquidity
Interest rates, the dollar and risk appetite still move crypto. When things get uncertain, money tends to leave speculative assets, not pile into them.
See both sides and don't marry one.
Here's what we think. Bitcoin has historically run on four-year cycles, the pattern will probably fade as the market matures, and the current cycle may well be the last one to follow it cleanly. That's a view. It's not a certainty.
So we plan for both. A portfolio that only works if the cycle repeats, or only works if it doesn't, isn't a plan. It's a bet.
Pick a plan that survives either answer, and you don't have to be right about the cycle at all.
My best advice, see both sides and don't marry one. Get all the information you possibly can, make sense of it. Create your own informed opinion.
What do you do in each phase?
Same plan, applied at different points in the cycle. None of it requires knowing exactly where the top or bottom is. Good, because nobody does.
- 01
Near a cycle low
Start or keep dollar cost averaging. Sentiment is at its worst and the headlines are loudest, which is exactly when a plan you made in advance earns its keep.
- 02
During the rally
Keep the schedule. If you use value cost averaging, deploy reserved capital only on the major corrections you defined ahead of time.
- 03
As euphoria builds
Scale out in stages instead of trying to sell the exact top. Taking profit is part of the plan, not a betrayal of it.
- 04
In the decline
Hold reserves somewhere safe and earning, review the journal, and use hedges or short positions only within your risk rules.
- 05
Always
Keep long-term holdings in self-custody and size every trade from its stop, whatever phase you think it is.
Using the cycle well
Why do most people buy at the wrong point in the cycle?
Because attention follows price. Always has. Most people discover crypto during a rally, when the moves are obvious and the stories are everywhere, and they buy in the middle or near the top. When the decline comes, they hold with no plan, then sell near the bottom. It's the most normal thing in the world. It's just expensive.
I call the root of it the HODL Paradox: the speed people expect from crypto is what pulls them in, and that same expectation pushes them to buy late and bail early. Understanding the cycle won't let you time it perfectly. It DOES let you recognize which part of that story you're standing in.
Does the cycle matter if you trade?
More than almost anything else on the chart. The cycle is the highest timeframe there is, and every smaller trend sits inside it. A short-term uptrend inside a cycle-level decline is a different trade from the same uptrend in a bull market, right? That relationship between small and large structure is the core of crypto trading strategies.
It also makes the case for bidirectional exposure. A portfolio that can only make money when prices rise accepts every bear market as a cost. One with a separate, rules-based trading sleeve can treat a decline as something to plan for, under the rules in crypto risk management.
What does a full cycle cost a buy-and-hold investor?
Historically? A lot, at least on paper. Holding from a cycle peak through the next decline has meant giving back half or more of the value, as we work through in holding on for dear life is not a plan. That's why an exit plan belongs in a portfolio from day one. See how to build a crypto portfolio, or start from the beginning of our crypto trading roadmap.
Cycle tops are also when unsolicited offers multiply, because that's when the most people are looking for a way in. Funny how that works. The checks in our due diligence check matter most when the market feels easiest.
So write down, today, what you'll do at the next cycle top and at the next cycle low. If you can't answer both, you don't have a plan yet... you have a position.
Common questions
The crypto market cycle is the repeating sequence of expansion, peak, contraction and bottom that crypto has moved through several times. For Bitcoin it has run about four years: roughly three years up, then roughly one year down that took about 84% off the peak in 2018 and about 77% in 2022. We treat it as context for decisions, not a forecast.
It's the pattern Bitcoin has historically followed: roughly three years of rising prices and one year of decline, lining up with its halvings every four years. The 2017 peak was followed by a 2018 low, and the 2021 peak by a 2022 low.
Nobody knows yet. Institutional flows, clearer regulation and government involvement are reasons it may fade. Human psychology, leverage and global liquidity are reasons it may persist. Our view is that the pattern will probably fade as the market matures, and we plan portfolios to work either way.
In Bitcoin's last two complete cycles, the decline from peak to low lasted roughly a year, from December 2017 to December 2018 and from November 2021 to November 2022. Past durations don't predict future ones.
Historically, a mix of Bitcoin's halvings, which cut new supply every four years, global liquidity, leverage building up and unwinding, and human psychology moving from fear to greed and back. The weight of each is shifting as institutions enter the market.
Not precisely. You can recognize broad phases and plan for them: accumulate steadily near lows, take profit in stages as euphoria builds and keep reserves for major corrections. Plans that depend on calling the exact top or bottom tend to fail.
Plan for both outcomes.
