On Monday, Bitcoin traded close to $85,800, hitting Oct. 5, 2026, which is the cycle-bottom date implied by the math in an anonymous 4chan post.
The price has gone up about 49% since its low point on July 1, which was around $57,700, Cryptopolitan calculations show.
The post appeared on December 12, 2023, on 4chan’s business board and can be found on Warosu’s archive. It listed four legs. From its low point in 2015 to its high point in 2017, Bitcoin went up for 1,064 days, then went down for 364 days to its 2018 low. From that low to its high point in 2021, it went up for another 1,064 days, then fell for 364 days to its 2022 low.
Based on that pattern, the poster said that the next all-time high would happen on October 6, 2025.
“People want to believe otherwise but the simulation will repeat itself,” the unknown poster wrote.
The highest Bitcoin price was worth $126,198 on October 6, 2025. The post didn’t give a bottom date, but adding its 364-day run to that peak lands on Oct. 5, 2026.

Cryptopolitan reported that a sell-off in late June pushed Bitcoin below $58,000 and forced the liquidation of a lot of leveraged positions. The low on July 1 was around $57,700.
As compared to past cycles with drops of 80% or more, 21Shares said this one wasn’t as bad. Bitcoin lost more than 14% of its value in the second quarter of 2026. The third quarter kept going in the green in July.
BTC is now about 32% below its October 2025 high. On Monday, the price hit a high point of about $86,970, which was $430 less than the late-September high point of near $87,400. It then fell about $1,000.
The rise on Monday was the second in a week to stop below that level. Friday’s weaker U.S. job data, with only 29,000 jobs added in September, eased the pressure on the Federal Reserve to keep raising rates.
Cryptopolitan reported in August that one research desk said the most likely bottom would be between October and December 2026, at $50,000 to $55,000. Another singled out the third quarter as a possible low.
The report also predicted a low point in the summer of 2026 if demand for ETFs kept the drawdown below 70%. It said the path was never seen before.
The April 2024 halving is linked to the late 2026 window. The report said that cycles in the past hit their lowest point 24 to 28 months after that. It also said that capitulation came in December 2018 at $3,200 and again at the end of 2022 at $15,500.
Also, the fourth quarter falls 12 to 15 months after the October 2025 peak, which is a normal amount of time for a bear market to last. The study said that a deep recession or stricter rules from the government could push the low into the first quarter of 2027.
Bitcoin is worth about $86,190 right now, which is 1.1% more than it was 24 hours ago.
