Bitcoin opened October at $83,823, up 0.28%, after closing September with a 6.33% gain. It had been up 7.33% with one trading day left, which would have edged past 2024's 7.29% for the best September on record, before a late correction took the top off it. Still green, still a break from the Red September pattern, no longer a record. On the Myriad prediction market, traders put 90% odds on Bitcoin reaching $85,000 and 70% on $87,500.
