History suggests Bitcoin's worst price of October tends to come in the first few days of the month, which is useful for buyers trying to time an entry.

• In green Octobers, the monthly low has usually landed around day four or five.
• Day two is the single most common day for that low to print.
• Across the first five days, the low shows up 60% of the time in past green Octobers.
• Red Octobers behave differently, with the low arriving even earlier in the month.

Outlook: If October closes higher, the cheapest prices of the month have probably already passed within its opening week.
