Market Cycle

A market cycle is a recurring sequence of market phases, usually described as accumulation, expansion (markup), distribution and decline (markdown), driven by changing prices, liquidity and sentiment.

The four phases

Accumulation follows a long decline: prices move sideways, sentiment is gloomy and patient buyers slowly build positions. Expansion, often called markup, is the rising phase in which more participants notice the trend and buy, pushing prices higher. Distribution is the topping phase: prices stall at high levels while early holders sell to newcomers. Decline, or markdown, follows as selling outweighs buying, sometimes ending in capitulation, when exhausted holders sell in large numbers.

The phases are easy to label in hindsight and hard to identify while you are in them. Each can last weeks or years, and markets can move back and forth between phases.

Cycles in crypto

Bitcoin's history has often been described in roughly four-year cycles, loosely aligned with its halvings, the scheduled events that cut the new supply of bitcoin roughly every four years. The fourth halving, in April 2024, cut the block reward to 3.125 BTC. Many analysts watch this pattern, but the sample is small and the market has changed a lot, with institutional products and macroeconomic factors such as interest rates and liquidity now playing a bigger role.

An example of sentiment shifting

Consider a hypothetical coin that trades flat near 10 for a year while hardly anyone talks about it. It then climbs to 40 as media coverage grows, stalls between 35 and 45 while headlines turn euphoric, and finally falls back to 15 as enthusiasm fades. Each stage drew different buyers and sellers with very different expectations.

Using the idea carefully

Thinking in cycles can help you notice when sentiment is extreme and avoid assuming that a trend will last forever. It is not a timetable. Treating past cycle lengths as a forecast can lead to buying or selling on dates that turn out to mean nothing, and a cycle can stretch, shorten or break completely.

Frequently asked questions

How long does a crypto market cycle last?

Bitcoin's past cycles have often been described as about four years, but that is an observation from a short history, not a rule, and future cycles may differ.

Can you tell which phase the market is in?

Only with uncertainty. Indicators such as sentiment, trading volume and on-chain data give clues, but phases are usually confirmed in hindsight.

Are market cycles unique to crypto?

No. Stocks, commodities and real estate also move in cycles; crypto cycles have simply tended to be faster and more extreme.
