What Are Bull and Bear Markets in Crypto?

You open your portfolio app and see green numbers everywhere. Your assets are up 20% in a week. Social feeds are full of profit screenshots and confident predictions about higher prices.

A few months later, it can look very different. Prices are down, news headlines are negative, and many people are wondering if crypto is “finished”.

These shifts between optimism and pessimism are often described as bull and bear markets. The terms come from traditional finance, but crypto markets can move faster, be more volatile, and react to different triggers. Knowing how these cycles work is one step towards becoming a more prepared and realistic investor.

The Bull Market: Optimism and Growth

A bull market is a period when asset prices are rising, or many people expect them to rise. In crypto, this usually refers to a sustained upward trend where major assets increase significantly in value, often by 20% or more from recent lows, and demand is stronger than supply.

Bull markets do not have a fixed length and they can include sharp drops along the way. What matters is the general direction over time.

How a bull market works

Bull markets often build on themselves. As prices rise, more investors feel confident. Some people buy because they believe in the long-term potential. Others buy because they see prices going up and do not want to be left behind.

Increased buying is sometimes called accumulation. Media coverage usually grows as prices climb, which can attract more retail and institutional investors.

In crypto, bull markets are not only about company profits or economic data. They are often linked to:

• New technology narratives, such as smart contracts or scaling solutions
• Network or protocol upgrades
• Global liquidity, such as low interest rates or loose monetary policy

You will often hear the term FOMO, which stands for Fear Of Missing Out. It describes the feeling of wanting to buy because others seem to be making gains. Acting based on FOMO alone is risky and can lead to poor decisions.

Signs you are in a bull market

• Sustained price appreciation
  Over time, prices of major cryptocurrencies such as Bitcoin and Ethereum rise, often lifting many other assets with them.

• Positive sentiment
  Social media, news articles, and sentiment indicators such as the “Fear and Greed Index” often show confidence or strong optimism for extended periods.

• Higher trading volume
  More people are trading and investing. Exchange activity increases and capital flows into crypto-related products and services.

• Altcoin outperformance (“altseason”)
  After strong moves in larger assets, some investors shift profits into smaller cryptocurrencies (altcoins). For a period, these may rise faster than the market leaders, but they can also fall harder when conditions change.

• Shallow pullbacks
  Price dips still occur, but many of them are brief. Traders often treat them as buying opportunities rather than signs that the trend is over.

The Bear Market: Pessimism and Correction

A bear market is the opposite of a bull market. It is a prolonged period of falling prices and weaker demand. In traditional markets, a drop of 20% or more from a recent high is sometimes used as a rule of thumb.

Crypto markets can be more extreme. A severe downturn, often called a “Crypto Winter”, may see some assets fall 80% or more from their peaks.

How a bear market works

In a bear market, sentiment usually shifts from confidence to caution or fear. Many investors expect further declines, so they sell to reduce risk or exit positions. When many people want to sell and there are fewer buyers, prices tend to move lower.

Crypto markets are open 24 hours a day, 7 days a week, and they do not typically use the same “circuit breakers” that some traditional exchanges use to pause trading during major moves. This can make price drops feel fast and relentless.

Bear markets can also serve a cleaning role. They often:

• Remove excess leverage from the system
• Reduce speculative activity
• Expose weak, fraudulent or unsustainable projects
• Bring valuations closer to levels that match usage and fundamentals

This process can be painful for investors, but it can also be part of longer-term market development.

Signs you are in a bear market

• Large price declines
  Major cryptocurrencies may lose a significant portion of their value. Historical cycles have seen peak-to-trough declines of 75% to 85% in some large assets, although the future may differ.

• Lower liquidity and activity
  Casual or short-term investors often leave the market. Trading volumes drop and order books can thin out, which may increase volatility because even smaller trades can move the price.

• High correlation
  In bear phases, many assets move together. When Bitcoin falls sharply, most other cryptocurrencies often fall at the same time, regardless of their individual qualities.

• Negative sentiment and “FUD”
  FUD stands for Fear, Uncertainty and Doubt. It describes a climate where negative news, online rumours, or regulatory concerns dominate discussions and may further weigh on confidence.

Real-life examples of market cycles

Looking at previous cycles can help you understand how bull and bear markets have played out in crypto so far. Past performance does not guarantee future results, but it can provide context.

The 2017 retail boom (bull)

In 2017, interest from individual (retail) investors rose sharply. The Initial Coin Offering (ICO) trend made it easy for new projects to raise funds by issuing tokens.

Bitcoin climbed close to 20,000 USD (around 17,000 EUR at late-2017 exchange rates). Many people heard about cryptocurrency for the first time. Alongside genuine innovation, there were also many low-quality and fraudulent offerings.

The 2018 crash (bear)

After the 2017 peak, the market fell into a deep correction. Over roughly a year, Bitcoin dropped by about 84% from its high. Many tokens from the ICO boom lost most of their value or disappeared.

This period showed how quickly sentiment can change and highlighted the risks of buying assets purely because prices are rising.

The 2021 DeFi and NFT summer (bull)

In 2020 and 2021, smart contract platforms grew in importance. Decentralised Finance (DeFi) services and Non-Fungible Tokens (NFTs) saw rapid adoption and speculation.

At its peak, the total crypto market capitalisation moved toward 3 trillion USD (around 2.5 trillion EUR at the time). Activity expanded far beyond simple payments and transfers, into lending, trading, gaming, art and more.

The 2022 deleveraging event (bear)

In 2022, several factors contributed to a sharp downturn. Global interest rates started to rise, which reduced liquidity and risk appetite. At the same time, some high-profile crypto projects and companies failed, including Terra and the FTX exchange group.

Bitcoin fell from close to 69,000 USD to under 16,000 USD (from roughly 60,000 EUR to under 15,000 EUR at the time). This period is often described as a deleveraging event, where unsustainable debt and risk-taking were forced out of the market.

Risks and how to stay safe

Bull and bear markets each carry different types of risk. Prices can move quickly in either direction. No strategy can remove risk completely, but understanding common pitfalls can help you make more informed choices.

Red flags in a bull market

• Scams and “rug pulls”
  When prices are rising and interest is high, scammers often try to take advantage of inexperienced investors. A “rug pull” is when developers or insiders suddenly remove liquidity or abandon a project, leaving token holders with little or nothing. Always check whether a project has transparent information on its team, code, and purpose, and whether it is audited by reputable firms.

• Emotional investing
  Buying an asset simply because it has gone up in price is risky. This behaviour, often driven by FOMO, can lead people to buy close to local peaks, then sell after a drop. A written plan and clear risk limits can help reduce emotional decisions.

• Over-leverage
  Some platforms allow users to borrow funds to trade with more exposure than their own capital, often called margin or leverage. While leverage can increase gains, it can also magnify losses and lead to forced liquidations if prices move against you. Leverage is a high-risk tool and is not suitable for most retail investors.

Navigating a bear market

• Panic selling
  Selling at any price just to “get out” is common in bear markets. For some investors, reducing exposure can be logical. For others, panic selling can lock in losses that they are later unhappy with. Many experienced investors try to base decisions on their time horizon, risk tolerance, and updated information, rather than on fear alone.

• Exchange and counterparty risk
  During severe downturns, some platforms may face liquidity problems, operational failures, or even insolvency. It is important to consider the quality of the platforms you use, including their regulation, security measures, transparency, and track record. For some users, self-custody wallets, where you control your private keys, can reduce reliance on third parties, although self-custody also introduces its own responsibilities and risks.

• Regular investing strategies
  Some investors choose a method such as Dollar Cost Averaging (DCA). This means investing a fixed amount at regular intervals, regardless of price. Over time, it can smooth the average purchase price, but it does not guarantee profits or protect against loss. Any strategy should match your financial situation and risk profile.

Summary: Navigating the cycle

Volatility is a normal feature of crypto markets. Prices can move up and down sharply, and neither bull nor bear phases last forever.

By understanding the typical signs of each phase, you may be better able to avoid buying purely during periods of euphoria or selling only because of fear. Many long-term investors focus on diversification, risk management, and the underlying fundamentals of the assets they hold, rather than short-term price swings.

No approach removes the risk of loss, including the risk of losing your entire investment. Only commit money that you can afford to lose, and consider seeking independent, regulated financial advice where needed.
