What is a bull market and bear market in crypto?

Bull markets and bear markets in crypto explained: what each phase looks like, why crypto cycles are sharper, and how to think about them.

By Oliver Crane · May 16, 2026

Crypto investors talk about a bull market in crypto and the bear market that follows as if everyone already knows what they mean. But the words carry more weight than people realise, and getting them wrong can shape the way you read prices, news and your own decisions. This guide explains what each phase actually is, where the words come from and how crypto cycles play out differently from anything you see in the stock market.

The Short Version

A bull market in crypto is a sustained period of rising prices and improving sentiment, while a bear market is the opposite.
In crypto, both moves tend to be sharper, faster and more emotional than in traditional markets.
There is no single official threshold, but a fall of around 20 percent from recent highs is often used as a rough marker for a bear market.
Crypto cycles have historically been linked to the Bitcoin halving, liquidity conditions and broader risk appetite.
Recognising which phase you are in matters more than predicting the next move, because it shapes the risks you are actually taking.

Where the bull and bear labels come from

The labels predate crypto by a long way. The most common explanation is that a bull attacks by thrusting its horns upwards, while a bear swipes downwards with its paws. The image stuck because it captures the feeling of each phase. A bull market in crypto feels like things are being lifted, with confidence rising and headlines turning optimistic. A bear market feels like things are being dragged down, with confidence draining and headlines turning sceptical.

In traditional finance, the phrases were used for centuries to describe stock markets and commodity markets. Crypto borrowed them in the early 2010s and has been using them ever since, often more loosely than equity investors do. There is no regulator or index committee in crypto that formally announces a sustained bull phase or its bear counterpart. The labels emerge from price action, social mood and the way the industry talks about itself.

What a bull market in crypto actually looks like

A bull market in crypto is more than a few good weeks of price gains. It is usually a phase that lasts months or longer, with several recognisable features.

Prices climb steadily across many coins, not just one. Bitcoin typically leads, then Ethereum joins in, and eventually attention spreads to smaller and more speculative tokens. Trading volumes rise. New users open exchange accounts. Headlines move from technical detail to bigger statements about money, technology and the future. New products launch, from exchange-traded funds to wallet apps. Companies that had gone quiet during the previous downturn start announcing partnerships and integrations again.

The mood inside the industry also shifts. Conferences fill up. Job listings reappear. Influencers start posting price charts more often than educational content. Some of this is healthy, because rising prices fund research and adoption. Some of it is the warning sign of late-cycle excess, when speculative behaviour starts to dominate genuine use.

An important point: a rising market is identified after it has begun, not on its first day. The strongest gains often come early, before most people are confident enough to call it a bull at all.

What a crypto bear market actually looks like

A bear market is the mirror image of a bull market in crypto. Prices fall across many assets, not just one. Bitcoin usually leads the fall, then drags everything else down with it. Smaller, more speculative tokens tend to lose the most. Trading volumes drop. Mainstream news coverage becomes negative, then sparse, then quiet for long stretches.

Inside the industry, layoffs start. Funding rounds shrink. Projects that looked promising during the boom quietly disappear. The vocabulary shifts. People stop talking about price targets and start talking about survival, build phases and fundamentals. Some of the most useful long-term work in crypto has historically happened in bear markets, when there is less noise and more time.

Bear markets are uncomfortable but not unusual. Every major crypto cycle so far has included one. They typically last longer than people expect and feel worse than the percentage decline suggests, because the optimism of the previous boom makes the contrast sharper.

Why crypto cycles are sharper than stock market cycles

Crypto markets move faster and further than equity markets for several reasons. They trade around the clock, with no opening bell, no closing bell and no circuit breakers in most venues. They are smaller in total value than major stock indices, which means a moderate flow of money in or out can move prices a long way. They are dominated by retail investors and traders using leverage, which amplifies both rallies and sell-offs.

There is also no central bank standing behind the asset class. When equity markets fall sharply, central banks sometimes signal support that calms the mood. Crypto has no such backstop. Prices are left to find their own floor, which often takes longer and goes further than people expect.

The history reflects this. Past examples of a bull market in crypto have multiplied Bitcoin’s price several times over within a single cycle. Past bear markets have wiped out 70 to 80 percent of Bitcoin’s value from its recent peak, and far more for smaller coins. Both moves would be considered extraordinary in a stock index, but they are normal in crypto. The Bank of England’s Financial Stability Report has discussed these dynamics in the context of broader risk to UK consumers.

How investors and analysts try to spot a turn

No one rings a bell at the top or the bottom of a crypto cycle. Most attempts to identify turning points combine several signals rather than relying on a single one.

Price relative to the previous peak is one starting point. A drop of around 20 percent from recent highs is often used as a rough marker for a bear market, borrowed from equity convention. A sustained rally of similar size from recent lows can mark the start of a bull market in crypto, although this is judged with even more caution.

Other signals include on-chain data such as the number of active wallets, the supply held by long-term holders and net flows in and out of exchanges. Sentiment measures such as the Crypto Fear and Greed Index attempt to capture the emotional temperature of the market. Macro conditions matter as well. Liquidity, real interest rates and the broader appetite for risk in global markets all feed into how crypto trades.

None of these tools is reliable enough to call a turn with confidence. They are most useful for understanding the environment you are in, not for timing trades.

A worked example

Picture a stylised crypto cycle, drawing on patterns seen in past markets without claiming any specific year.

Bitcoin rises from a quiet base price over several months. Volumes pick up. Ethereum follows. Headlines begin to mention crypto more often. New investors open exchange accounts. Around six months in, smaller coins begin to outperform Bitcoin, often by large multiples. Conferences are packed. Wallet downloads surge. This is the heart of a bull market in crypto.

Then a shift. Prices stop making new highs. A few negative headlines appear, perhaps a regulatory action or a high-profile failure. Bitcoin falls 25 percent from its peak. Smaller coins fall further, some by 60 percent or more. Many investors decide this is a temporary dip and buy more. Prices rally briefly, then fall again. After several months, Bitcoin sits 70 percent below its peak, and the loudest voices from the previous bull market in crypto have gone quiet. This is the heart of a bear market.

The cycle eventually turns. Bitcoin stops falling and trades sideways for a long stretch. Builders keep working. Volumes are low. Few headlines appear. Then quiet accumulation gives way to a slow rise, and the pattern starts over. The exact shape of each cycle varies, but the broad rhythm has been remarkably consistent in crypto so far.

What This Means For You

Knowing which phase you are in does not tell you what will happen next. What it does is sharpen the questions you should be asking yourself.

In a bull market in crypto, the temptation is to assume that recent gains will continue and to take on more risk than usual. The honest question is whether you would still be comfortable with your position if prices fell by half or more. If the answer is no, that is information.

In a bear market, the temptation is to assume that recent falls will continue and to step away from the market entirely. The honest question is whether your reasons for being interested in the first place have changed, or whether only the price has. If only the price has changed, the bear may be a quieter period to learn, rather than a reason to leave.

Either way, the size of any crypto position relative to your overall finances matters more than the timing. Crypto is highly volatile and you could lose all of your investment. Money you cannot afford to lose has no business in this market in either phase of the cycle.

In Plain English

A bull market in crypto is a long stretch when prices rise and confidence builds. A bear market is the opposite, a long stretch when prices fall and confidence drains. The names come from the way the animals attack, with a bull lifting upwards and a bear striking down. Both phases are normal parts of the crypto cycle. The hard part is not predicting which one is coming next, but knowing what you are doing while you are in one.
