A bull market is a long period of rising prices and optimism. A bear market is a long period of falling prices and pessimism. The names are said to come from how each animal attacks: a bull thrusts its horns up, a bear swipes its paws down.
Crypto markets are far more extreme than stock markets. Gains in a crypto bull market can be several hundred percent, and declines in a bear market have repeatedly wiped out more than three quarters of Bitcoin’s value — and even more for altcoins. Knowing what each phase looks like helps you avoid the emotional mistakes that cost most people money.
Key takeaways
- A common definition of a bear market is a fall of 20% or more from a recent high; in crypto, bear markets have been far deeper.
- Bitcoin fell roughly 84% after its 2017 peak and about 77% after its 2021 peak.
- Euphoria and fear both lead to bad decisions — have a plan before the market moves.
- Nobody reliably times the top or the bottom.
Bull market: what it looks like
- Prices make higher highs and higher lows over months.
- Trading volume, new users and app downloads rise; crypto appears in mainstream news.
- New tokens launch every day and many rise sharply, regardless of quality.
- Borrowing and leverage grow, which makes later crashes more violent.
Late in bull markets, money tends to rotate from Bitcoin into smaller altcoins (so-called altseason), and stories of overnight millionaires attract newcomers — often near the top.
Bear market: what it looks like
- Prices make lower highs and lower lows; rallies fade quickly.
- Trading volume and media attention drop.
- Weak projects run out of money and shut down; some lenders and exchanges fail.
- Sentiment turns to fear and disinterest — «crypto is dead» headlines appear.
Bear markets are painful but also when many durable projects keep building quietly.
How deep crypto bear markets have been
| Cycle | Approximate BTC peak | Approximate BTC low | Drawdown |
|---|---|---|---|
| 2013–2015 | ~$1,150 (Dec 2013) | ~$170 (Jan 2015) | about −85% |
| 2017–2018 | ~$19,700 (Dec 2017) | ~$3,200 (Dec 2018) | about −84% |
| 2021–2022 | ~$69,000 (Nov 2021) | ~$15,500 (Nov 2022) | about −77% |
Many altcoins fell 90% or more in the same periods and never recovered. Past cycles are often linked to the Bitcoin halving, but past patterns are no guarantee of future ones.
Signs traders watch
No single signal is reliable, but traders often watch:
- Price structure on weekly charts and moving averages such as the 200-week average — see how to read crypto charts.
- Total market cap and Bitcoin dominance.
- Funding rates and open interest in futures markets, which show how much leverage is in the system.
- Stablecoin supply growth, a rough proxy for new money entering crypto.
- Sentiment indices that summarise fear and greed.
How to handle a bull market
- Decide in advance at what prices or portfolio size you will take some profit.
- Avoid leverage — liquidations are how many people lose everything at the top.
- Be extra sceptical of new tokens and guaranteed-return schemes; scams multiply in bull markets.
- Keep enough in fiat or stablecoins that a crash would not force you to sell.
How to handle a bear market
- Only hold what you can afford to see fall 80%.
- If you are investing long term, steady dollar-cost averaging removes the need to guess the bottom.
- Move funds off exchanges you are unsure about — failures cluster in bear markets. See CEX vs DEX.
- Use the quiet period to learn and to review which projects are still shipping and used.
Frequently asked questions
How long do crypto bear markets last?
Historically, roughly one year from peak to bottom, followed by a long sideways recovery. There is no rule that future cycles will be the same.
What is a correction?
A shorter decline of around 10–20% inside a larger trend. Crypto bull markets usually contain several sharp corrections.
What does ‘buy the dip’ mean?
Buying after a price drop in the hope it recovers. In a bear market, dips can keep going lower for a long time, which is why many people prefer a scheduled DCA plan.
Is now a bull or a bear market?
Only hindsight confirms which phase we were in. This site does not give investment advice — focus on a plan you can stick to in both.
