If you've watched bitcoin for any length of time, you've noticed it doesn't behave like a normal stock. It goes up violently for a year or two, then crashes, then sits sideways for a long stretch, then goes up violently again. People who've been around for a while talk about "cycles" like everyone knows what that means.

Here's the mental model.

The four-year rhythm

Roughly every four years, bitcoin has a halving — a built-in software event that cuts the rate of new bitcoin being created in half. Less new supply, same or growing demand, and prices have historically run higher in the 12–18 months after each halving.

Halvings happened in 2012, 2016, 2020, and 2024. The next one is around 2028.

This isn't magic. It's just supply economics applied to a fixed-supply asset, and the four-year rhythm is consistent enough that traders plan around it.

The four phases

Inside each cycle, you typically see four phases:

  1. Accumulation — prices have crashed, news is bad, retail interest is low. This is when long-term holders quietly buy.
  2. Markup — prices start grinding up. Halfway through, everyone notices. Headlines turn positive.
  3. Distribution — prices are near all-time highs. Your dentist mentions bitcoin. New money pours in just as long-term holders are quietly selling.
  4. Markdown — prices fall 60–80%. News is bad again. Retail blames everyone. Cycle resets.

We're currently in what looks like late markup, maybe early distribution. That's why every headline feels like it's screaming.

Why this matters for a normal person

You can't time the cycle. People who say they can are wrong even when they're right, because they can't repeat it. But knowing the cycle exists gives you two useful instincts:

  • Don't chase price into euphoria. When everyone is talking about bitcoin and you feel pressure to "get in before it's too late," that's usually closer to a top than a bottom.
  • Don't capitulate in the markdown. When prices are down 70% and the news is awful, that's usually closer to a bottom than the end of the world.

This is the entire reason dollar-cost averaging is the recommended strategy for beginners — it sidesteps the cycle by buying a little bit every week regardless of price.

Takeaway

The cycle isn't a guarantee. The 2024 cycle behaved differently from the 2020 one, which behaved differently from 2016. The pattern is rough, not precise. But the underlying truth — that bitcoin's volatility is rhythmic, not random — is the one mental shift that separates panicked beginners from calmer ones.

Crypto is volatile. The cycle has historically rewarded patience and punished urgency. Only invest what you can afford to leave alone for a full cycle.
