A bull market is a sustained price rise; a bear market is a sustained fall. Key differences in crypto, the 20% rule, a real drawdown example and FAQs.

Bull market vs bear market describes the two broad phases of a market: a bull market is a sustained period of rising prices and optimism, while a bear market is a sustained period of falling prices and pessimism. In crypto both phases tend to be more extreme than in stocks, and knowing which one you are in shapes how much risk makes sense.
A bull market is a prolonged uptrend: prices make higher highs and higher lows, trading volume and new users grow, and sentiment is confident. The image is a bull thrusting its horns upward.
A bear market is a prolonged downtrend: prices make lower highs and lower lows, activity dries up and sentiment turns fearful. The image is a bear swiping its paws downward.
In traditional finance, a common rule of thumb defines a bear market as a fall of 20% or more from a recent peak, and a bull market as a rise of 20% or more from a recent low. Crypto routinely moves 20% in weeks, so the rule is less useful there. Traders tend to judge crypto phases by duration, the depth of the drawdown from the all-time high and broad sentiment rather than a single threshold.
Crypto markets have tended to move in a rough cycle:
Drivers include liquidity and interest rates, regulation, major hacks or failures, and crypto-specific events such as Bitcoin halvings. None of them make a cycle's timing predictable.
| Bull market | Bear market | |
|---|---|---|
| Price trend | Higher highs and higher lows | Lower highs and lower lows |
| Sentiment | Optimism, FOMO | Fear, capitulation |
| Activity | Rising volume, new users, new tokens | Falling volume, projects shut down |
| Main risk | Buying the top, overusing leverage | Panic selling, holding failing projects |
A real example: Bitcoin peaked near 69,000 USD in November 2021 and fell to around 15,500 USD by November 2022, a drawdown of roughly 77%, during the bear market that followed the 2021 bull run (figures as reported by Glassnode and contemporary coverage, checked 10 October 2026).
Now the maths of drawdowns, as a hypothetical. Say you hold 10,000 USD of a token at its peak and it falls 77%. You are left with 2,300 USD. To get back to 10,000 USD the token has to rise 10,000 ÷ 2,300 − 1 ≈ 335%. A 50% drop needs a 100% gain to recover; a 90% drop needs a 900% gain. Losses in a bear market are much harder to win back than they look, which is why position size matters more than timing.
Our crypto investing guide for beginners covers how to build a plan that survives both phases.
A bull market is a sustained period of rising prices and optimism. A bear market is a sustained period of falling prices and pessimism. In traditional finance a 20% move from a recent low or high is the common rule of thumb.
A crypto bear market is a long downtrend in which prices fall well below their previous highs, activity and funding dry up and weaker projects fail. Crypto bear markets have historically seen much deeper drawdowns than stock bear markets.
The names come from how each animal attacks: a bull thrusts its horns upward, like rising prices, while a bear swipes its paws downward, like falling prices.
