BTC Basis Bot Hits 91% Win Rate, But Its Edge Is Slowly Fading

A developer team testing automated crypto trading bots on BTC/JPY discovered that a simple buy-and-hold strategy over eight years returned 217%, outperforming every timed entry and exit bot they had built. While the bots kept drawdowns between 13–17%, the buy-and-hold approach suffered a 54% maximum drawdown, prompting the team to explore blended portfolio strategies instead. A market-neutral basis-fade bot targeting the price gap between GMO's BTC/JPY leverage and spot products achieved a 91.3% win rate and a near-zero 0.39% drawdown. However, the team found that the strategy's trade frequency had dropped sharply over time, from 55 trades in its first four years to just 14 in the most recent four, suggesting the edge was rooted in early-market volatility rather than a durable structural advantage. Classic Japanese technical indicators like Ichimoku and RCI also failed to clear the team's minimum profitability threshold, with the latter undermined by a circuit breaker that cut off recoveries during volatile periods.
