Wall Street’s famous adage “Sell in May and go away” seems to apply to cryptocurrency markets too. Historical data shows Bitcoin often underperforms during this month, whether through limited gains or outright declines. While analysts caution against blindly following seasonal patterns, understanding these trends helps investors make informed decisions.

Multiple studies of Bitcoin’s price action reveal a consistent pattern:
- 2018-2024 Average Returns: May ranks among the bottom 3 months for BTC performance

Why This Seasonal Pattern Exists
Several factors contribute to Bitcoin’s May slump:
1. Institutional Investment Cycles
- Q1 portfolio rebalancing often leads to profit-taking
- Traditional markets’ “Sell in May” sentiment spills into crypto
2. Technical Factors
- Miner reward halvings historically cause pre-event rallies and post-event corrections
- Options expiries in late April/early May increase market volatility
3. Macroeconomic Trends
- Federal Reserve policy meetings often occur in early May
- Tax season liquidity crunches in major markets
Should You Actually Avoid Buying Bitcoin in May?
While the data suggests caution, experts recommend nuance:
✅ Dollar-cost averaging still works regardless of seasonality
✅ Major corrections can present buying opportunities
✅ Altcoins sometimes decouple from Bitcoin’s trends
Key consideration: The 2024 halving’s delayed effects might disrupt traditional patterns.
