"Buy when RSI drops below 30, sell when it rises above 70" — this is perhaps the most commonly taught RSI strategy. It sounds logical: buy when the market is oversold, sell when it's overbought. But does mean reversion actually work for Bitcoin? The answer might surprise you.

## Strategy Rules

- **Buy** when RSI(14) drops below 30 (oversold)
- **Sell** when RSI(14) rises above 70 (overbought)
- Hold position until the opposite signal triggers

- 100% position size — fully in or fully out
- 0.1% transaction fee per trade
- No leverage, no short selling
## Backtest Results

Period: 2017-08-30 to 2026-03-23 (8.6 years)

Strategy CAGR-5.3%
Buy & Hold CAGR37.9%
Strategy Max Drawdown-83.3%
B&H Max Drawdown-83.2%
Total Trades35
Win Rate57.1%
Win/Loss Ratio0.8x
Time in Market46.9%

## Key Findings

This strategy loses money. A -5.3% CAGR means you would have actually lost capital over 8.6 years while Bitcoin gained 1469.1%.

Bitcoin doesn't mean-revert — it trends. When RSI drops below 30, it often means Bitcoin is entering a bear market, not that it's about to bounce. You're buying into weakness and selling before the real rally.

The max drawdown of -83.3% is worse than Buy & Hold's -83.2%. You took on MORE risk for NEGATIVE returns.

Compare this with RSI trend following (53.2% CAGR) — the exact opposite approach. Using the same indicator in the opposite direction produces dramatically better results.

## The Verdict: Don't Mean-Revert Bitcoin

This is a textbook example of why you must backtest before trading. The most intuitive use of RSI — buy oversold, sell overbought — doesn't work for Bitcoin. Bitcoin is a trending asset. Mean reversion strategies belong in range-bound markets, not in crypto.
