For years, crypto believers have sworn by the so-called four-year Bitcoin cycle. Like seasons, the market was said to bloom after each halving when mining rewards are cut in half. Then fade into a cold winter before the next big rally.
But according to Arthur Hayes, co-founder of BitMEX and one of crypto’s most outspoken thinkers, that rhythm no longer applies. And if he’s right, Bitcoin may have entered an entirely new age — one ruled not by time, but by monetary policy.
The Myth of the Four-Year Rhythm
In his recent blog post, Hayes didn’t mince words: the old pattern “will fail this time.”
He says the idea that Bitcoin’s price is tied to a simple four-year timer has always been a convenient myth. It’s easy to chart, easy to believe, but not grounded in the real forces that move global markets.
Instead, he argues, Bitcoin’s rises and falls have always been a reflection of how much money is flowing through the world’s two largest economies, the United States and China.
In plain terms, it’s not about halvings. It’s about liquidity.
When central banks print, loosen, and flood the economy with cheap money, Bitcoin thrives. When they tighten, pull back, and raise interest rates, Bitcoin sinks. The pattern, Hayes says, has never been about the blockchain’s internal clock—it’s about the financial heartbeat of the global economy.
Why This Cycle Is Different
So what makes this current bull run stand apart? Hayes points to several major factors and they all lead back to one theme: money is flowing again.
- The U.S. Treasury has been injecting about $2.5 trillion back into the markets, largely by draining the Federal Reserve’s Reverse Repo Facility essentially taking idle cash and letting it circulate again.
- President Donald Trump, according to Hayes, wants to “run it hot,” meaning he’s not interested in austerity or belt-tightening. He’s pushing for looser monetary policy to stimulate growth, even at the risk of inflation.
- Plans to deregulate banks and expand lending could pour even more liquidity into the system.
On top of that, the Federal Reserve has already resumed cutting interest rates. This is despite inflation sitting above target. Futures markets now predict a 94% chance of another rate cut in October and an 80% chance of a second one in December.
Hayes’ takeaway? The money taps are turning back on, and history shows that when liquidity rises, Bitcoin tends to follow.
Bitcoin’s Real Cycles: A Monetary History
Hayes’ argument doesn’t stop at theory. He points to three earlier Bitcoin booms as proof that global money supply, not halving events, has driven every major bull run so far.
- 2013: Bitcoin’s first big rally aligned with massive quantitative easing in the U.S. and a Chinese credit surge. It crashed when both central banks tightened liquidity.
- 2017: The “ICO cycle” was powered by Chinese credit expansion and yuan devaluation. When China’s credit growth slowed, the market imploded.
- 2021: The “COVID cycle” was born out of the Federal Reserve’s pandemic-era money printing. When the Fed reversed course in late 2021, Bitcoin’s rally ended just as quickly.
Each time, the pattern was clear: when global money gets cheaper, Bitcoin soars. When it tightens, the party ends.
Why China Might Not Stop the Rally
In past cycles, China’s monetary tightening often acted like a wet blanket on Bitcoin’s flames. But this time, Hayes says, the situation is different.
Rather than draining liquidity, Beijing is now trying to “end deflation.” That means it’s at least neutral, or even mildly supportive when it comes to credit expansion.
This removes a major headwind. Without Chinese deflation offsetting U.S. money printing, the global flow of liquidity could remain positive — a perfect storm for Bitcoin’s continued climb.
“Listen to our monetary masters in Washington and Beijing,” Hayes writes. “They clearly state that money shall be cheaper and more plentiful. Therefore, Bitcoin continues to rise in anticipation of this highly probable future.”
Old Beliefs Die Hard
Not everyone agrees with Hayes, of course. Many analysts still insist that Bitcoin moves in clear halving cycles.
On-chain data firm Glassnode recently argued that “from a cyclical perspective, Bitcoin’s price action still echoes prior patterns.” Others, like Gemini’s Saad Ahmed, believe that even if the cycle’s length changes, some form of periodic rhythm will remain.
Still, Hayes’ perspective adds an important dimension: Bitcoin isn’t just a technology anymore—it’s a macroeconomic asset, deeply tied to the global flow of money.
The New Reality
If Hayes is right, traders may need to rethink how they measure time in crypto. The market’s not moving to the beat of halvings— it’s dancing to the tune of central banks.
In this new reality, Bitcoin’s cycles don’t start when the code says so. They start when policymakers decide that money should move and stop when it doesn’t.
So maybe the four-year cycle isn’t dead after all, maybe it’s just evolved. It’s no longer about block rewards; it’s about monetary rhythm. And right now, that rhythm is getting louder.
