Former bitcoin bull sounds alarm on potential year-long crypto winter, says Fidelity director

Fidelity’s Director of Global Macro, Jurien Timmer, says the most recent bitcoin bull run has likely run its course, while highlighting the continued strength of gold’s rally.

A long-time supporter of bitcoin, Timmer has become more cautious on the asset, arguing that its price action appears to be lining up once again with the cryptocurrency’s four-year cycle. From both historical analogs and time-based analysis, he believes the current phase closely resembles previous market cycles.

Bitcoin’s October peak near $125,000 — reached after roughly 145 months of cumulative gains — fits well within that framework, Timmer said. He noted that bitcoin bear markets, often referred to as crypto winters, have typically lasted about a year, leading him to see 2026 as a potential pause following the latest halving-driven rally.

“While I remain a secular bull on bitcoin, my concern is that bitcoin may well have ended another four-year halving phase, both in price and time,” Timmer wrote on X. “If we visually line up all the bull markets, we can see that the October high of $125,000 after 145 months of rallying fits pretty well with what one might expect. Bitcoin winters have lasted about a year, so my sense is that 2026 could be a year off for bitcoin. Support is at $65,000 to $75,000.”

In contrast, Timmer pointed to gold’s strong showing in 2025, noting that the metal remains firmly in a bull market while bitcoin has struggled. He added that he does not expect a near-term convergence between the two assets.

Gold is up roughly 65% year to date, outpacing growth in the global money supply, Timmer said. He also noted that gold has retained most of its gains during recent market pullbacks — a pattern he views as consistent with a durable bull market.
