Bitcoin has now gone 10 months since its October 2025 top, and the market’s old four-year cycle debate is back in focus. The question is simple: when does this cycle bottom, and when is the best time to buy into weakness?
BlockBeats compiled views from several well-known market figures, and a number of those calls place the likely bottom in the second half of the year, with October showing up repeatedly.
Brandt and Jiang Zhuoer both point to October
Veteran trader and chart analyst Peter Brandt said in late July that he expects Bitcoin to bottom for this market cycle on Oct. 4, 2026. He also said that buying Bitcoin now could produce better returns over the next two to three years than investing in AI stocks.
Looking further out, Brandt expects the next cycle top to arrive in 2029, with a target range of $250,000 to $300,000 for Bitcoin.
Jiang Zhuoer, founder of B.TOP, used the prior three Bitcoin halving cycles to estimate the low for the current bear market. His projection puts the BTC bottom at $44,016, with the low appearing on Oct. 31.
Killa and CryptoD offer broader timing ranges
Other traders gave less precise windows.
Killa said the bottom may form between July and September. CryptoD, who previously made more than $10 million from a single TRUMP meme coin trade, said the broader crypto market is gradually approaching a bottom, adding that 「Q3 and Q4 will likely be the last stretch before the next bull market when positions can still be built calmly.」
A viral 4chan “oracle” post also points to October
Brandt’s and Jiang Zhuoer’s October-bottom view lines up closely with a widely circulated anonymous “oracle” post on 4chan.
Historical records show that the post was published on Dec. 12, 2023. It listed the time intervals between four major Bitcoin cycle highs and lows since 2015: ATL 2015 to ATH 2017 at about 1,064 days; ATH 2017 to ATL 2018 at about 364 days; ATL 2018 to ATH 2021 at about 1,064 days; and ATH 2021 to ATL 2022 at about 364 days.
Using that pattern, the post arrived at a conclusion that Bitcoin would top on Oct. 6, 2025. If that same logic is extended, Bitcoin would also bottom in October this year.
Whether the cycle still behaves the same is unresolved
BlockBeats added one note of caution: this line of analysis may amount to forcing old patterns onto a changed market. In the current cycle, institutional capital has already reshaped Bitcoin’s market structure, and a shift in cycle behavior would not be surprising.
