Crypto Volatility in a Bull Run: Why 30% Pullbacks Are Normal
Crypto pullbacks in a bull run explained: why 30% drops have been common even in strong rallies, what causes them, and how to plan so they don't shake you out.
Crypto pullbacks in a bull run are normal: past bitcoin rallies, including 2017 and 2020–2021, saw several drops of around 30% or more before the eventual peak, and many altcoins fell much further during the same moves. A sharp drop does not by itself mean a bull market is over, and it does not mean it will continue. It means crypto is volatile, in both directions.
This guide explains why large pullbacks happen even in strong uptrends, what history up to mid-2025 shows, how to tell a healthy correction from a deeper problem, and how to prepare so a 30% drop in 2026 or 2027 does not push you into a bad decision.
What History Shows About Bull Market Pullbacks
Looking at past cycles up to mid-2025:
- 2017: Bitcoin's run to its late-2017 peak was interrupted by several sharp drops, some approaching 40%, including one tied to regulatory news from China in September.
- 2020–2021: After rising strongly through late 2020 and early 2021, bitcoin fell by roughly half between April and July 2021, then went on to set a new high later that year before the 2022 bear market.
- 2024: After setting a new high in March 2024, bitcoin went through months of choppy, sometimes sharp declines before resuming its uptrend later in the year.
The pattern is consistent: strong rallies have rarely moved in a straight line. Each of these drops felt, at the time, like it could be the end of the cycle, and commentators confidently argued both ways. Only hindsight showed which were pauses and which were peaks.

Why Big Pullbacks Happen in Rising Markets
Several forces combine to cause sudden drops:
- 1Leverage unwinds. When many traders hold leveraged long positions, a small drop triggers liquidations, which force selling, which triggers more liquidations. See leverage in a bull run.
- 2Profit-taking. After large gains, holders sell to lock in profits, especially around round numbers or previous highs.
- 3Macro surprises. Unexpected interest rate news or turmoil in traditional markets can hit crypto alongside other risk assets.
- 4Crypto-specific shocks. Exchange problems, hacks, regulatory actions or large token unlocks.
- 5Thin liquidity. Weekend and holiday trading can have shallower order books, so moves are larger.
Normal Pullback or Something Worse?
You usually cannot know in the moment, but these signals help separate the two over weeks:
| Signal | Often seen in a pullback | Often seen in a deeper downturn |
|---|---|---|
| Leverage | Funding resets, open interest drops, then stabilizes | Leverage keeps getting flushed out with each bounce |
| Flows | ETF and stablecoin flows remain supportive | Persistent outflows and shrinking stablecoin supply |
| Structure | Recovers to higher highs within weeks or months | Lower highs and lower lows over months |
| Fundamentals | Unchanged | Major failure, policy shock or loss of confidence |
| Sentiment | Quick swing to fear, then recovery | Fear that persists and deepens |
Our guide on bull traps versus real breakouts goes deeper into these distinctions.
How to Prepare for Volatility in 2026 and 2027
The time to plan for a 30% drop is before it happens:
- 1Stress-test your portfolio. Ask: "If everything I hold fell 30% tomorrow, and altcoins fell 50%, would I be forced to sell?" If yes, your positions are too large.
- 2Keep an emergency fund outside crypto, so you never need to sell during a crash to pay bills.
- 3Write dip rules in advance. For example, "If bitcoin falls 20% from its recent high, I add a fixed amount; at 35%, I add another fixed amount; I never add more than X in total."
- 4Set alerts instead of watching charts. Use price alerts for the levels in your plan.
- 5Check sentiment objectively. The Fear & Greed Index often swings to fear during pullbacks, which can help you recognize emotional reactions, including your own.
Why altcoins fall harder
Smaller tokens usually have thinner order books, more leveraged traders relative to their size and holders who are quicker to sell. When the market drops, traders often sell their riskiest positions first to raise cash or meet margin calls. That is why a 30% fall in bitcoin has frequently coincided with much larger percentage drops in small caps. For a deeper look, see Volatility in Crypto.
Common Mistakes During Pullbacks
- Panic selling at the low after holding through the entire decline.
- Using leverage to "buy the dip," which can be liquidated if the dip deepens.
- Averaging down endlessly into a small token whose fundamentals have broken.
- Rotating into riskier coins to "make it back faster."
- Trusting recovery services or "guaranteed" signals that target people who just lost money. Fake recovery services specifically target people who have just lost money.
Risk Management: Volatility Is the Price of Admission
Volatility is the reason crypto can rise quickly, and the same force produces painful drops. A practical framework:
- Size positions for drawdowns, not for best-case gains. Our guide on position sizing and risk management shows how.
- Avoid leverage, which is the main reason pullbacks wipe people out.
- Take partial profits on the way up so pullbacks hurt less. See how to take profits in a bull run.
- Prefer spreading purchases over time through dollar-cost averaging rather than lump sums after big rallies.

Bottom line
Crypto pullbacks in a bull run of 30% or more have been normal in past cycles, and altcoins usually fall harder. You cannot reliably tell a healthy correction from the start of a bear market in real time, so build a plan that survives both: modest position sizes, no leverage, an emergency fund and pre-written rules.

คำถามที่พบบ่อย
How big are pullbacks in a crypto bull run?
In past bitcoin bull runs, including 2017 and 2020–2021, there were several drops of around 30% or more before the final peak. Altcoins have often fallen even further during the same pullbacks. The exact size varies, so plan for large drops rather than assuming any specific number.
How can I tell a pullback from the start of a bear market?
In the moment, you often cannot. Pullbacks within uptrends have tended to recover as liquidity, flows and sentiment stay supportive, while bear markets show persistent outflows, weakening fundamentals and lower highs over months. Rather than guessing, use position sizes and rules that work in both cases.
Why does crypto fall so sharply even in a bull market?
Common causes include leverage being unwound through liquidations, profit-taking after big gains, macro news such as interest rate surprises, large token unlocks or exchange problems, and thin weekend or holiday liquidity. When many traders use borrowed money, a modest drop can trigger forced selling that turns into a much larger one.
Should I buy the dip during a bull run?
Some investors add during pullbacks using pre-set rules, such as buying a fixed amount at set drawdown levels. The risk is that a dip turns into a prolonged decline. Spreading purchases over time, avoiding leverage and keeping cash for emergencies outside crypto reduces the damage if the dip keeps going.
