A bull market is a sustained rise in prices with optimistic sentiment; a bear market is a sustained fall with pessimistic sentiment. The usual rule of thumb is a 20% move in a broad index over at least two months. Bitcoin's bear markets have gone far deeper, with falls of 53% to 85% since 2013.
What is the difference between a bull and a bear market?
| Feature | Bull market | Bear market |
|---|---|---|
| Rule-of-thumb definition | Rise of 20% or more over at least two months | Fall of 20% or more over at least two months |
| Sentiment | Optimism, then greed and euphoria | Fear, then capitulation and apathy |
| Trading activity | Rising volume as new buyers arrive | Falling volume as investors leave |
| Media coverage | Mainstream and positive | Negative or absent; "crypto is dead" headlines |
| Smaller tokens | Often outperform Bitcoin late in the rally | Usually fall further; many never recover |
| Typical mistake | Buying with borrowed money near the top | Selling everything near the bottom |
The 20% definition comes from stock markets; the SEC's Investor.gov glossary uses it for both terms. For crypto it is a low bar, because Bitcoin often moves 20% within a few weeks without any change in the longer trend. Bull and bear phases are part of the wider crypto market cycle, which also includes accumulation and distribution phases.
How long do crypto bull and bear markets last?
Bitcoin's history gives the clearest data. The table uses daily closing prices from Coin Metrics, so intraday highs and lows were slightly more extreme.
| Cycle | Peak close | Lowest close after peak | Fall | Peak to low | Time to regain peak |
|---|---|---|---|---|---|
| 2013β2015 | $1,135 (4 Dec 2013) | $176 (14 Jan 2015) | β84.5% | 13 months | 39 months (Feb 2017) |
| 2017β2018 | $19,641 (16 Dec 2017) | $3,185 (15 Dec 2018) | β83.8% | 12 months | 35 months (Nov 2020) |
| 2021β2022 | $67,542 (8 Nov 2021) | $15,758 (9 Nov 2022) | β76.7% | 12 months | 28 months (Mar 2024) |

Two patterns stand out. The decline from peak to low has taken about a year in each completed cycle, but getting back to the old high has taken two to three years. And each completed bear market has been slightly shallower than the one before, although three data points are not enough to rely on.
What drives crypto bull markets?
Bitcoin supply cuts
Roughly every four years the Bitcoin halving cuts the new supply issued to miners by half. In each of the last four cycles, Bitcoin's peak came 12 to 18 months after a halving: about 12 months after November 2012, 17 months after July 2016, 18 months after May 2020 and 17.5 months after April 2024. Four observations are a pattern, not a law; see Bitcoin halving explained.
New access and demand
New ways to buy bring new money. The SEC approved the listing of spot bitcoin exchange-traded products on 10 January 2024, opening Bitcoin to investors who use ordinary brokerage accounts.
Cheap money and leverage
Low interest rates push investors towards riskier assets, and borrowed money amplifies rallies late in a cycle.
What drives crypto bear markets?
- Tighter money. Between March and December 2022, the US Federal Reserve raised its target rate range from 0β0.25% to 4.25β4.50%. Bitcoin fell 77% from its November 2021 peak over the same broad period.
- Failures and contagion. The collapse of the TerraUSD stablecoin in May 2022 and of the FTX exchange in November 2022 forced lenders and funds to sell. Bitcoin fell 14.9% on 9 November 2022 alone.
- Leverage unwinding. Falling prices trigger liquidations of borrowed positions, which push prices lower still.
- Exhaustion. After a long rally, early buyers take profits and new buyers run out.
How should you invest through bull and bear markets?
The investors who come through full cycles in good shape usually keep the same plan in both phases rather than switching strategies:
- Hold a crypto allocation small enough to survive an 80% fall without selling; see crypto risk management.
- Keep buying on a schedule through bear markets with dollar-cost averaging.
- Rebalance in bull markets when crypto grows past its target weight.
- Avoid leverage, which turns a temporary fall into a permanent loss.
The evidence on whether you can time the crypto market shows why calling the turn is so hard. Diversifying across crypto assets helps with single-project failures but not with a market-wide fall: Ether dropped 79% and Bitcoin 77% in the 2021β2022 bear market. The Wealtii Digital Asset Core Index Fund, for example, holds seven crypto assets at fixed target weights (Bitcoin via BTCB 33.9%, BNB 13.4%, NEAR 12.2%, Ether 12.1%, Chainlink 9.7%, Cardano 9.4%, Zcash 9.3%, as of 21 October 2026) and would be expected to fall in a crypto bear market too.
Frequently Asked Questions
What is a bull market in crypto?
A bull market is a sustained period of rising prices and optimistic sentiment. The common rule of thumb, used by the SEC's Investor.gov, is a rise of 20% or more in a broad market index over at least two months. In crypto, bull markets are usually marked by rising volume, new investors and strong altcoin rallies.
What is a bear market in crypto?
A bear market is a sustained period of falling prices and pessimistic sentiment, generally a fall of 20% or more over at least two months. Crypto bear markets are much deeper than that threshold: Bitcoin fell between 77% and 85% from peak to low in each of the three bear markets that ended in 2015, 2018 and 2022.
How long do crypto bear markets last?
In Bitcoin's last three completed cycles, the fall from peak to lowest daily close took 12 to 13 months, and regaining the previous peak took 28 to 39 months from that peak, based on Coin Metrics data. Three cycles are a small sample, and the 2025 to 2026 decline reached its lowest close so far after about nine months.
Is crypto in a bull or bear market right now?
As of 20 October 2026, Bitcoin closed at $82,899, which is 34% below its 6 October 2025 peak but 42% above its 30 June 2026 low. By the 20% rule it is in a bear market measured from the peak and a bull market measured from the low, which shows why the labels are only clear in hindsight.
