The first crypto cycle I lived through cost me four figures and most of my confidence. I bought in mid-2021, watched everything go vertical for a few months, then sat through 18 months of the price screen turning my portfolio into a slow burn. The lesson wasn’t about which coin to pick. It was about which phase of the cycle I was in — and the fact that I had no idea.
Six years and two full cycles later, the cycle framework is the single most useful mental model I use. This is what I wish someone had drawn on a napkin for me on day one.
Short answer: The crypto market cycle is a roughly 4-year boom-bust pattern tied to the Bitcoin halving (which cuts new BTC supply in half every ~210,000 blocks). It moves through four phases: accumulation (sideways, smart money buys), markup (price runs up), distribution (smart money sells), and markdown (capitulation). Each cycle has rhymed but never repeated exactly. The current cycle has been shaped by ETF flows and institutional demand in ways the previous three weren’t.

Key takeaways
- The crypto market cycle has historically followed a ~4-year pattern, anchored to Bitcoin’s halving schedule.
- Four cycles so far: 2011–2013, 2013–2017, 2017–2021, and the current 2021–2025+ cycle.
- Cycles move through accumulation, markup, distribution, and markdown — each phase rewards different behaviour.
- The 2024 halving cut block rewards from 6.25 BTC to 3.125 BTC, the smallest supply shock so far in percentage terms.
- ETF approval, institutional flows, and macro liquidity are changing how this cycle behaves compared to the previous three.
The 4-year cycle hypothesis
The 4-year cycle hypothesis is the idea that Bitcoin (and by extension the whole crypto market) moves in a roughly four-year boom-bust pattern, anchored to the Bitcoin halving.
Why four years?
The Bitcoin protocol cuts the block subsidy in half every 210,000 blocks. At a target of one block every 10 minutes, that works out to roughly every four years. Each halving slashes the rate at which new BTC enters circulation. Less new supply, same or growing demand, price rises. That’s the supply-shock thesis.
The pattern that emerged from the first three cycles: halving happens, price grinds higher for 12–18 months, blows off in a euphoric top, then crashes 70–85% over the following 12 months, then bottoms and starts grinding sideways before the next halving.
Why it might not be a law
The 4-year cycle is observation, not physics. With only three completed cycles to study, the sample size is small. Plenty of analysts argue the cycle will lengthen, shorten, or break entirely as Bitcoin matures and institutional flows replace retail euphoria.
I don’t treat the cycle as a rule. I treat it as the strongest base case until proven otherwise. The full halving mechanics are in bitcoin halving explained.
Historical cycles
A walkthrough of the cycles we have on the record.
Cycle 1: 2011–2013
The first cycle. Bitcoin went from cents to roughly $32 in 2011, crashed back to single digits, then ran to roughly $1,160 by late 2013 before crashing 85% to $200 over the following year. Almost no altcoins existed. The whole market was Bitcoin and a handful of speculative forks.
Cycle 2: 2013–2017
The first halving (November 2012) preceded the 2013 top. The second halving (July 2016) preceded the 2017 ICO mania top. Bitcoin went from $200 in 2015 to roughly $19,800 in December 2017. Ethereum launched in 2015 and rallied from cents to $1,400 by January 2018. Then the crash — Bitcoin fell to $3,200 by December 2018, ICO tokens fell 95%+.
Cycle 3: 2017–2021
The third halving (May 2020) was followed by the biggest cycle yet. Bitcoin went from a 2018 bottom of $3,200 to a November 2021 peak around $69,000. Ethereum went from $90 to $4,800. The cycle had two peaks — April 2021 and November 2021 — separated by a mid-cycle correction. DeFi summer (2020), NFT mania (2021), and meme coin season all fit inside this cycle.
The crash: Bitcoin bottomed at roughly $15,500 in November 2022 after the FTX collapse. Down about 77% from the top.
Cycle 4: 2021–2025+
The fourth halving (April 2024) is the most recent. Cycle 4 has been the strangest so far. Bitcoin reclaimed all-time highs before the halving (a first), spot Bitcoin ETFs were approved by the SEC in January 2024 (the largest structural change since the asset launched), and institutional demand has dominated flows. According to SEC filings, spot BTC ETFs absorbed over $50 billion in net inflows in the first 18 months after launch.
Where this cycle peaks and how deep the markdown goes is the question of the next 18 months.
The 4 phases
Every cycle moves through the same four phases. The names come from Wyckoff market structure analysis, used by traders since the 1920s.
Phase 1: Accumulation
Price is sideways or in a slow grind higher. Sentiment is awful. Headlines are negative. Retail is gone. The news cycle is full of “crypto is dead” articles. This is when patient capital — funds, miners, dedicated holders — quietly stacks BTC at low prices.
Accumulation phases have historically lasted 12–18 months. The 2018–2020 accumulation lasted about 18 months. The 2022–2023 accumulation lasted about 14 months. Recognising you’re in accumulation is hard because nothing exciting happens — that’s the whole point.
Phase 2: Markup
Price breaks out of the accumulation range and starts a sustained uptrend. Higher highs, higher lows. Volume picks up. Mainstream news starts to notice. Retail starts to trickle back in, then pour in.
Markup is the longest profitable phase. It typically runs 12–18 months from breakout to top. Bitcoin tends to lead first, then ETH, then large-cap alts, then mid-caps, then small-caps and memes. This is the alt season pattern — covered in detail in bitcoin dominance explained.
Phase 3: Distribution
Price tops out and starts chopping sideways near the highs. New retail keeps buying because price still looks bullish. Smart money is selling into their bids. Sentiment is euphoric — taxi drivers, family WhatsApp groups, and TikTok influencers all start talking about which coin is going to 100x.
Distribution can last 2–6 months. It often produces multiple local highs that look like new breakouts but fail. The first crack often comes as a flash crash that recovers within 24 hours, then another a few weeks later. By the time most retail accepts the top is in, BTC is already 40% off the high.
Phase 4: Markdown
The painful one. Price collapses in waves — sharp drops, dead-cat bounces that lure dip buyers, then more drops. Altcoins fall hardest. The losses compound: a 50% drop needs a 100% recovery just to get back to even.
Markdown phases have historically lasted 9–14 months from cycle top to cycle bottom. Bitcoin has fallen 70–85% from peak to trough in each completed cycle. Altcoins commonly fall 90–95%. Then sentiment hits the floor, accumulation begins again, and the cycle restarts.
Why halvings drive cycles (the supply shock thesis)
The supply-shock thesis is the cleanest explanation for the 4-year pattern. It works like this.
Block rewards and inflation
Every Bitcoin block contains a block subsidy paid to the miner. The subsidy started at 50 BTC per block. It halves every 210,000 blocks (roughly every four years).
The schedule:
| Halving | Year | Block reward before | Block reward after |
|---|---|---|---|
| First | November 2012 | 50 BTC | 25 BTC |
| Second | July 2016 | 25 BTC | 12.5 BTC |
| Third | May 2020 | 12.5 BTC | 6.25 BTC |
| Fourth | April 2024 | 6.25 BTC | 3.125 BTC |
Each halving cuts Bitcoin’s annual inflation rate in half. The 2024 halving brought Bitcoin’s annual inflation to roughly 0.85% — below gold’s mining inflation rate for the first time in history.
The supply-demand argument
Miners sell most of their block rewards to pay for electricity, hardware, and operations. The block reward is therefore the main source of new BTC entering exchanges. When the block reward halves, the rate of new BTC entering circulation halves. If demand stays flat (or grows), price has to rise to clear the market.
This is the supply-shock thesis in a sentence. It has predicted every Bitcoin cycle top within 12–18 months of the halving so far. According to CoinDesk’s cycle analysis, Bitcoin’s price has rallied on average 7–10x from the bottom of each cycle to the top.
The criticism
Supply shock is only half the story. The other half is demand — and demand has been driven by very different forces each cycle. 2013 was speculation. 2017 was ICO mania. 2021 was DeFi, NFTs, and stimulus money. 2024+ is ETFs and institutional flows. The halving is the trigger. What the market does with that trigger depends on the macro context.
What’s different about the current cycle
If you’re trying to plan a strategy around the current cycle, you need to know how it differs from the last three.
Spot Bitcoin ETFs
The single biggest change. The SEC approved 11 spot Bitcoin ETFs in January 2024. BlackRock, Fidelity, Ark, Bitwise, and others now offer Bitcoin exposure inside traditional brokerage accounts. According to Bloomberg ETF research, spot BTC ETFs broke records as the fastest-growing ETF launch in history.
Why it matters: every previous cycle, retail had to actively choose to onboard onto a crypto exchange. Now any investor with a Vanguard or Schwab account can buy Bitcoin in two clicks. That changes the demand curve entirely.
Institutional demand
Treasury companies (MicroStrategy and copycats), corporates, pension funds, sovereign wealth funds — all are buying or studying Bitcoin in a way they weren’t in 2021. Institutional flows are stickier than retail flows. They don’t panic-sell on a 30% drawdown. That should change the shape of the markdown phase if it happens this cycle.
Macro liquidity
Each cycle has tracked global liquidity (M2 money supply, central bank balance sheets) closely. The current cycle has been shaped by post-COVID liquidity injections, tightening cycles, and the eventual easing turn. According to the IMF’s macro data, global liquidity conditions are the single highest correlated macro factor to Bitcoin price over multi-year windows.
Diminishing returns
Each cycle has produced smaller percentage gains than the one before. Cycle 2 saw BTC go from $200 to $19,800 (99x). Cycle 3 went from $3,200 to $69,000 (22x). The current cycle, even at all-time highs, has so far produced a smaller multiple from the bottom.
The reason is simple: the bigger an asset gets, the harder it is to double it. A $1 trillion asset doubling requires $1 trillion in new buying. A $100 billion asset doubling requires $100 billion. Bitcoin’s market cap is now so large that 100x cycles are mathematically harder.
The post-halving lag
In Cycle 4, Bitcoin made new all-time highs before the halving — a first in crypto history. That suggests the cycle timing is shifting. Either the lag from halving to top is shrinking, or this cycle’s peak is still ahead of us at a much higher level than the pre-halving high.
Signs of each phase
How to actually recognise which phase you’re in. This is the hard part.
Signs of accumulation
- Price has been sideways for 6+ months in a range.
- Mainstream news mentions crypto in negative or dismissive terms.
- Search interest (Google Trends for “Bitcoin”) is near multi-year lows.
- Exchange BTC balances are falling — coins are moving to cold storage.
- Altcoin volume is dead. New token launches go nowhere.
- Your friends who were “into crypto” don’t talk about it anymore.
Signs of markup
- Price has broken out of a multi-month range with strong volume.
- Higher highs and higher lows on the weekly chart.
- BTC dominance climbs first, then starts to roll over as alts catch up.
- New all-time highs (eventually) — this is the major confirmation.
- Mainstream coverage shifts from sceptical to cautiously positive.
- Your non-crypto friends start asking how to buy.
Signs of distribution
- Price chops sideways near all-time highs for weeks or months.
- Volume on rallies is lower than volume on dips.
- Multiple failed breakouts — looks like a new high, fails within days.
- Funding rates on perpetual futures stay persistently positive (crowded long).
- Mainstream coverage is full of price-target predictions in the hundreds of thousands.
- Taxi-driver indicator. The TikTok indicator. Your barber indicator. Pick one.
Signs of markdown
- A flash crash that doesn’t fully recover.
- A failed bounce. Price rallies 20% then makes a lower low.
- Funding rates flip negative as longs get washed out.
- Altcoin liquidations dominate exchange feeds.
- News cycle shifts to scams, bankruptcies, regulatory crackdowns.
- The community gets quiet. Group chats die.
How to position across phases
Here’s what I actually do in each phase. None of this is advice — it’s the framework I run.
In accumulation: DCA and patience
Dollar-cost averaging is the playbook in accumulation. Buy a fixed amount on a fixed schedule, regardless of price. You’re not trying to catch the exact bottom. You’re stacking at prices that will look cheap in 18 months.
In the previous accumulation phase I ran a weekly DCA into BTC and ETH. Set it once, executed automatically. Didn’t look at price. The full setup is in how to buy bitcoin.
In markup: hold, rotate, take partial profits
The markup phase is the easiest to be wrong about. Almost any holding strategy works because everything is rising. The temptation is to chase the latest narrative. The discipline is to stay in the assets you bought during accumulation and rotate slowly into alts as the cycle progresses.
I take partial profits during markup — usually 10-20% of a position when it doubles. That gets my original capital back and lets the remainder ride. The best crypto trading strategy post covers this in detail.
In distribution: take serious profits, move to cold storage
The hardest phase mentally. Everyone is euphoric. Selling feels like leaving money on the table. The math says you’re closer to a top than a bottom.
My distribution playbook:
- Take 30–50% of profits across positions. Move stablecoins off the exchange into a separate wallet or savings account.
- Move long-term BTC and ETH to cold storage. A Ledger Nano X (affiliate) is the device I use. How to store crypto safely covers the process.
- Stop adding to alt positions. No new chases.
- Set price alerts and step back. Watch the chart less often.
In markdown: cash, patience, study
The painful phase. The point is not to lose more. Cash and stablecoins outperform almost everything else.
My markdown playbook:
- Don’t try to call the bottom. It will look like the bottom several times before it actually is.
- Don’t add to losing alt positions. The mantra is: don’t average down on a bag that has fallen 70%.
- Start studying. Read whitepapers, learn new strategies, plan the next cycle’s positioning.
- Start a small DCA into BTC. Tiny amounts. You’re laying foundations, not trying to time the bottom.
The mistakes most retail makes
Every cycle produces the same mistake pattern from retail traders. I made every one of them in 2021.
Mistake 1: FOMO at the top
The single biggest. Most retail buys near the peak because that’s when crypto is in every headline and every group chat. They see green for weeks, finally cave, buy at the top, then ride it down 70%. This is the textbook distribution-phase blunder.
The cure: have an entry plan before you have FOMO. If you didn’t buy during accumulation, you missed the cycle. Wait for the next one.
Mistake 2: Capitulation at the bottom
The flip side. After 12 months of pain, most retail sells what’s left for tax losses or just to make the chart stop hurting. They sell within weeks or months of the actual bottom.
The cure: know which phase you’re in. If you’ve held through the worst of the markdown, the bottom is closer than the next leg down. Selling at the bottom locks in losses that compounding will not recover from.
Mistake 3: Chasing narratives
Every cycle has a narrative that retail piles into late. NFTs in 2021. ICOs in 2017. The narrative is real — but by the time it’s mainstream, the early money is selling to you. Joining late narratives is how most retail loses money even in a bull market.
The cure: if it’s on the front page of a mainstream news site, the trade is mostly done.
Mistake 4: Over-leverage
Markup phases make leverage feel free. Everything is going up — why not 5x your position? Then a 20% retrace liquidates your account. Markup phases are punctuated by 20–30% corrections that liquidate over-leveraged longs.
The cure: stay on spot during the early markup. Treat futures as a small percentage of your portfolio, with strict stop losses. The best crypto trading strategy post covers leverage in detail.
Mistake 5: Not having an exit plan
Most retail spends 100% of their time planning entries and 0% planning exits. Then the top comes and they freeze. Six months later, the gains are gone.
The cure: write your exit plan before you enter. At what price do you take 25% off? 50%? At what BTC dominance do you start rotating? At what total market cap do you go fully to stables? Write it down. Read it once a month.

Learning to read cycles properly
Reading cycles is a skill. Anyone can identify a phase in retrospect. Identifying one as it’s happening is hard.
A few things that have helped me:
- Keep a journal. Note where you think we are in the cycle each month, and why. Look back six months later and see if you were right.
- Watch the same charts every week. Bitcoin price, BTC dominance, total market cap, ETH/BTC. The same four. Build pattern recognition.
- Read history. Read post-mortems of previous cycles. The 2018 and 2022 bear market post-mortems are some of the most useful crypto content ever written.
- Find people who’ve traded through full cycles. Most people in crypto have only seen one. Find the ones who’ve seen three.
That last one is why I joined Trade Travel Chill (affiliate). It’s a community of traders who’ve been through full cycles, and the cycle reading they share is the closest thing to a structured education in this stuff I’ve found. The crypto trading psychology side of cycle trading — staying calm in markup, taking profit in distribution — is what they drill the hardest.
For the chart-reading side, how to read crypto charts covers the basic technical analysis you need.
Storage strategy across cycles
The cycle determines how you store crypto, not just whether you hold it.
Accumulation: exchange or self-custody, mostly self-custody
In accumulation, you’re stacking for a multi-year hold. Long-term holdings belong in cold storage, not on an exchange. A Ledger Nano X (affiliate) handles BTC, ETH, and most major chains. Ledger Nano X review has the full breakdown.
Markup: split between exchange and storage
Markup is when active trading and long-term holding live in tension. The active trading float goes on the exchange. The long-term bag stays in cold storage. The split I run is roughly 15% on exchange, 60% in cold storage, 25% in mid-term yield products. I top up cold storage from exchange profits, not the other way around.
Distribution: aggressive move to cold storage
This is where exchange risk peaks. Volume is high, exchanges are stretched, and any black swan event would hit during distribution. Move profits off exchanges into cold storage or stablecoin wallets. Treat the exchange as a trading venue, not a vault.
Markdown: cash off exchange, BTC in cold storage
In markdown, the question isn’t yield, it’s preservation. Stablecoins held off exchanges. BTC held in cold storage. Yield-chasing in markdown is how 2022 caught so many people — Celsius, BlockFi, Voyager all collapsed during markdown phases because their yield models broke when markets collapsed. The full storage playbook is in how to store crypto safely.
Common storage mistakes across cycles
- Leaving long-term holdings on an exchange “just for now” — and finding “now” never ends.
- Forgetting where you stored a seed phrase. The lost seed phrase post covers what to do if it happens.
- Self-custody mistakes: wrong network, wrong address, sending to a contract that doesn’t accept the token.
- Storing seed phrase in a cloud document. Don’t.
Frequently asked questions
How long is a crypto market cycle?
A full crypto market cycle has historically lasted roughly four years, tied to the Bitcoin halving schedule. Cycles include 12–18 months of accumulation, 12–18 months of markup, 2–6 months of distribution, and 9–14 months of markdown.
When is the next crypto bull run?
The current bull run started during 2023–2024, anchored to the April 2024 halving. If the historical pattern holds, the cycle top would be expected 12–18 months after the halving — so somewhere in the 2025–2026 window. Past timing is not a guarantee of future timing.
What is the Bitcoin 4 year cycle?
The Bitcoin 4-year cycle is the observed pattern where Bitcoin price rallies after each halving event, tops 12–18 months later, then crashes 70–85% over the following year, then accumulates and starts again. It is anchored to the halving schedule, which cuts new BTC supply in half every ~210,000 blocks.
What are the four phases of a crypto cycle?
Accumulation (sideways, smart money buys), markup (price rallies), distribution (smart money sells at the top), and markdown (price collapses). These are the four phases of the Wyckoff market structure framework, applied to crypto.
Is the crypto cycle dead?
Some analysts argue the 4-year cycle will break this time due to ETF flows, institutional demand, and changing macro conditions. Others argue the cycle is intact and just shifting in timing. The honest answer is nobody knows — the sample size of completed cycles is only three.
How do I know if we’re at the top?
There’s no single signal, but combinations help: BTC dominance dropping below 45%, total market cap stalling at all-time highs, funding rates persistently positive, mainstream coverage saturated with price-target predictions, retail FOMO peaking. Multiple signals at once raise the probability of being near a top.
When does the crypto bear market end?
Bear markets have historically ended 12–14 months after the cycle top, with Bitcoin down 70–85% from the peak. The bottom is usually marked by a final capitulation flush, followed by 6–12 months of sideways accumulation before the next markup begins.
Should I sell at the top or hold forever?
That depends on your goals. Holders who never sell capture the full long-term thesis but ride 70–85% drawdowns every cycle. Traders who sell in distribution lock in cycle gains but risk missing the next leg. Most successful traders I know do both — keep a long-term core position and trade a smaller portion of capital across cycles.

Final word
The cycle is the most useful mental model in crypto. It tells you what to expect, when to be aggressive, and when to be patient. It is also the most ignored — because most people enter crypto during markup phases and never bother to learn what came before.
If you’ve never sat through a full cycle, your job is to learn the framework before you experience it. If you have sat through one, your job is to remember what it felt like and not repeat the mistakes. The cycle is the schedule the market runs on. The traders who survive are the ones who run on the same schedule.
Right — over to you.
