The 4 Phases of a Crypto Market Cycle Explained
By Menno — 13 years in crypto, 3 bear markets survived, zero paid promotions
Last updated: March 2026
Crypto market cycles move through four repeating phases: accumulation (bear market bottom, low sentiment), expansion (early bull, rising prices), euphoria (peak sentiment, maximum overvaluation), and contraction (bear market, declining prices). Recognising which phase you are in determines what action to take — buying, holding, selling, or waiting.
Key Takeaways
- •The four crypto cycle phases — accumulation, expansion, euphoria, contraction — repeat across every major cycle, driven by human psychology and Bitcoin halvings.
- •Accumulation (bear bottom) offers the best risk-reward for buying; euphoria (bull peak) is when to be selling.
- •Bi-weekly RSI below 36, Fear & Greed below 20, and altcoin risk scores below 15 are the convergent indicators that define the accumulation phase.
- •Bitcoin leads in early expansion, then dominance falls as altcoin capital rotation begins — this transition marks the best altcoin entry window.
- •The contraction phase requires capital preservation and patience, not active trading — the goal is to arrive at the next accumulation phase with dry powder.
Why Crypto Follows Cycles and Why They Repeat
Crypto market cycles are not random. They are driven by a predictable combination of human psychology, monetary policy shifts, and Bitcoin's halving mechanism — which reduces new Bitcoin supply by 50% approximately every four years.
The halving creates a supply shock that historically precedes the expansion phase. But the magnitude and timing of each cycle are amplified by human emotion: greed drives prices far above fundamental value at the peak, and fear drives them far below fundamental value at the bottom. These emotional extremes overshoot in both directions, creating the volatile cycles that define crypto.
Understanding cycles does not mean you can time them perfectly. It means you can orient yourself correctly — knowing whether you are early, late, or at an extreme — and allocate capital accordingly. The investor who correctly identifies the accumulation phase has a fundamentally different experience from the one who buys during euphoria.
Phase 1 — Accumulation: Where Wealth Is Built
Accumulation is the bear market bottom. Prices have already fallen 70–85% from their peak. Sentiment is at its worst. The community has fractured: many participants have left permanently, convinced that crypto is over. Media coverage is almost entirely negative. Retail investors are not buying — they are recovering from losses and swearing off the asset class.
This is exactly where the most profitable purchases in crypto history have been made. In late 2022, Bitcoin sat below $16,000. In 2018–2019, it spent months below $4,000. In both cases, investors who accumulated during these windows made extraordinary returns in the following 12–24 months.
The indicators that define the accumulation phase: bi-weekly RSI below 36, Fear & Greed Index below 20, prices near or below the 200-week moving average, altcoin risk scores in the 0–15 range, and historically low trading volume. When most of these align, you are in or near the accumulation zone.
Phase 2 — Expansion: The Earliest Opportunity After the BottomPremium
The expansion phase begins when Bitcoin establishes a new higher low after the bear market bottom and starts trending upward on increasing volume. Sentiment remains cautious — most participants believe it is another dead-cat bounce. This scepticism is actually a feature, not a bug, because it keeps new retail entrants out and allows prices to build a genuine technical base.

Frequently Asked Questions
How long does a full crypto cycle last?▾
Historically, from peak to peak, crypto cycles have lasted approximately 4 years — roughly aligned with Bitcoin's halving cycle. The bear market phase typically lasts 12–18 months. This is a rough guide, not a guarantee; cycles can be shorter or longer depending on macroeconomic conditions.
How do I know which phase the market is in right now?▾
Monitor the bi-weekly RSI, Fear & Greed Index, Bitcoin dominance, and altcoin risk scores together. Each phase has a characteristic fingerprint across these indicators. No single signal is definitive, but the aggregate picture usually gives a clear phase identification.
Does every altcoin follow the same cycle?▾
Most altcoins broadly follow the Bitcoin cycle, but with higher amplitude — bigger gains in expansion and euphoria, bigger losses in contraction. Some projects do not survive the contraction phase at all. Fundamental quality determines which altcoins emerge from each bear market ready for the next cycle.
What if I miss the accumulation phase entirely?▾
Early expansion still offers excellent risk-reward. You will not buy the absolute bottom, but you will still be entering before euphoria, before media attention, and before the majority of retail capital. Missing the exact bottom by 30–50% in a cycle that will produce a 500–1,000% gain from the bottom is an acceptable outcome.

How to Use Bitcoin Dominance to Time Altcoin Entries
Bitcoin dominance measures Bitcoin's share of total crypto market cap. When dominance falls from a high level — typically dropping below 50–52% after peaking near 60–65% — it historically signals the start of altcoin outperformance. Understanding this cycle allows investors to shift allocations at the right time rather than chasing altcoin moves after they have already run.
How to Read the Bi-Weekly RSI as a Crypto Cycle Indicator
The bi-weekly (two-week) RSI is a momentum indicator that, when applied to Bitcoin's price chart, has historically reached oversold levels only at major market cycle bottoms. When it falls below 35, every instance to date has represented a high-probability accumulation zone. It is Menno's single most-cited macro confirmation signal.
How to Identify Altcoin Season (And How to Position)
Altcoin season begins when Bitcoin dominance falls from its cycle peak (typically 60–65%), the overall market is in an uptrend, and capital starts rotating from Bitcoin into mid and small cap altcoins. The four indicators that confirm altcoin season are: falling Bitcoin dominance, rising total altcoin market cap, increasing altcoin volume relative to Bitcoin, and the Altcoin Season Index reading above 75.
How to Survive a Crypto Bear Market Without Panic-Selling
Surviving a crypto bear market requires a pre-built plan, not in-the-moment decisions. The investors who come out ahead are those who set aside cash before the drawdown, continue DCA buying into low-risk zones, and resist the urge to sell at maximum fear. Bear markets are where the next cycle's profits are built.
