Crypto Market Cycles: Bull & Bear Markets Explained (2026)

April 25, 20269 min readpoly-sim.com

Crypto markets move in identifiable cycles, largely driven by Bitcoin's halving schedule. Understanding where you are in the cycle is one of the most valuable edges a crypto investor can have — and prediction markets increasingly provide real-time probability data on cycle milestones.

The 4-Year Bitcoin Cycle

Bitcoin undergoes a halving every ~210,000 blocks (~4 years), cutting the block reward in half. This reduces new BTC supply, historically triggering bull markets 6–18 months after the halving as demand meets shrinking supply. The cycle has played out in 2012, 2016, 2020, and 2024.

The four phases of each cycle:

🌱 Accumulation
Post-bear bottom. Sideways price. Smart money accumulates quietly.
🚀 Bull Run
Price accelerates post-halving. Retail FOMO enters. New ATHs set.
💥 Distribution
Smart money sells into retail. Euphoria peaks. Blow-off top forms.
❄️ Bear Market
80%+ drawdown typical. Capitulation, despair, and narratives die.

Historical Cycle Performance

On-Chain Metrics to Time the Cycle

MVRV Z-Score

Compares Bitcoin's market cap to its "realised cap" (cost basis of all coins). High Z-scores historically mark cycle tops; low scores mark bottoms. It's one of the most reliable cycle-timing signals available.

Stock-to-Flow (S2F) Model

Measures scarcity by comparing existing supply to annual new production. Post-halving, Bitcoin's S2F ratio doubles, historically correlating with price appreciation. The model has critics, but S2F remains widely referenced.

Puell Multiple

Compares daily miner revenue to its 365-day moving average. Extreme high values signal miners selling into strength (distribution); extreme low values signal miner capitulation (accumulation zone).

📊 Prediction Market Angle

Polymarket runs BTC price prediction markets constantly. Cycle-aware traders use these markets to express views on "Will BTC hit $X by [date]?" — and track how sophisticated money is positioning around key halving milestones. These markets often price in cycle dynamics weeks before mainstream media covers them.

Why Cycles May Be Weakening

With Bitcoin ETFs absorbing institutional demand continuously, some analysts argue the clean 4-year cycle is becoming less predictable. Macro factors (Fed policy, global liquidity) now correlate more strongly with BTC price than in previous cycles. This doesn't eliminate cycles — it layers them on top of a macro backdrop that can either amplify or suppress the halving effect.
