The Four-Year Pattern

Bitcoin's price history is characterised by extreme volatility structured around recurring market cycles: multi-year periods of explosive appreciation followed by prolonged and severe drawdowns. These cycles have roughly corresponded with the Bitcoin halving schedule — occurring approximately every four years — though the relationship is correlational, not mechanistically proven.
Since Bitcoin's first meaningful market price in 2010, the following major cycles have occurred:
- 2011: Rise to ~$30, crash to ~$2 (93% drawdown)
- 2013: Two peaks, high ~$1,200, crash to ~$150 (88% drawdown)
- 2017–2018: Peak ~$20,000, crash to ~$3,200 (84% drawdown)
- 2020–2022: Peak ~$69,000, crash to ~$15,500 (78% drawdown)
- 2023–2024: Recovery and new all-time high above $100,000
Each cycle has brought a higher absolute price peak and attracted a new wave of institutional and retail participants.
Why Cycles Occur

Several explanations have been proposed, with likely truth in multiple:
Halving supply shock: every four years, new supply issuance is halved. If demand remains stable or grows, reduced supply creates upward price pressure. This mechanism is predictable and priced in to some degree, but may still drive marginal price appreciation.
Speculative momentum: Bitcoin has no cash flows or fundamental valuation anchor. Price is entirely determined by supply and demand, making it highly susceptible to self-reinforcing momentum — rising prices attract new buyers, who push prices higher, attracting more buyers. This momentum can operate in both directions.
Institutional and retail adoption waves: each bull market has been accompanied by a new category of adopter entering the market — first early adopters, then retail investors, then corporate treasuries (MicroStrategy, Square), then ETF investors following the January 2024 US Bitcoin spot ETF approvals.
Leverage and liquidation: crypto derivatives markets allow highly leveraged positions. Bull markets accumulate leveraged long positions; when prices fall, forced liquidations amplify the downside, turning corrections into crashes.
Investing Across the Cycle

The extreme amplitude of Bitcoin cycles creates obvious opportunities for investors who can time entries near cycle lows and exits near cycle highs. In practice, this is extremely difficult: peaks and troughs are only obvious in retrospect, and investor sentiment typically peaks at price peaks (maximum optimism) and bottoms at price lows (maximum fear).
Dollar-cost averaging (DCA) — investing a fixed amount at regular intervals regardless of price — is the standard risk-management approach for long-term Bitcoin investors who believe in the asset but accept they cannot time cycles reliably.
