Bitcoin Cycle Debate: 30% Top Probability vs Lengthening Cycle to Late 2025

The debate over Bitcoin’s next market top is intensifying, with veteran trader Peter Brandt and analyst Colin Talks Crypto offering sharply different timelines.

Brandt: 30% chance the top is already in

Brandt warned there’s a 30% probability Bitcoin has already peaked in this bull cycle. If so, he expects a retracement toward $60,000–$70,000 by late 2026, before the next parabolic advance could catapult prices to $500,000. His view emphasizes caution, suggesting investors may be underestimating how early a market top can form.

I think there is a 30% chance that BTC has topped for this bull market cycle. Next stop then back to $60k to $70k by Nov 2026, then next bull thrust to $500k https://t.co/xPujqCjp9e

Colin: Cycles are lengthening, next peak due Dec 2025

In contrast, Colin Talks Crypto points to a pattern of lengthening cycles—each extending by roughly four months compared to the last. His chart shows:

• Cycle 1: 24 months
• Cycle 2: 28 months
• Cycle 3: 33 months
• Current cycle: potentially 37 months

Using this model, the next Bitcoin top would arrive in December 2025, three years after the November 2022 bottom. This aligns with his earlier October 2025 projection, reinforcing the idea of one more strong push higher before the market peaks.

What it means for traders

Both views highlight the theme of diminishing returns but differ on timing. Brandt suggests caution, warning that a premature peak may already be behind us. Colin’s model argues the final rally is still ahead, giving bulls over a year to push higher.

The tension between these scenarios reflects the uncertainty of crypto cycles. Whether Bitcoin has already topped or still has 12–15 months left of upside momentum could define the strategies traders adopt for the next two years.
