Buy Bitcoin only after it has fallen a long way. The trigger is a close 20 percent below its average price over the last 25 days. Bitcoin trades every day, including weekends, so its chart has more points than a stock chart. Buy at the next day open. Sell when the price gets back to that average, or sell at a small loss if it falls below its recent low first. If neither happens in 20 days, sell anyway.
Period: 2016-11-01 to 2026-10-30. Trades in this test: 28. Final cumulative profit and loss in this test: -35.4%.
