What Triggers 70%+ Crypto Drawdowns? Lessons From 2018, March 2020, and 2022 (What’s Different Now)

Expert guides, insights and articles updated for 2026

Published 3 hours ago

Checking your portfolio and seeing -30% in a day feels like chaos. But the reputation-making drawdowns—the 70%+ wipeouts people warn about—usually aren’t random. They tend to follow a repeatable script.

This piece is a post‑mortem of 2018, March 2020, and 2022 to answer one question: what tends to trigger 70%+ crypto drawdowns? Then we’ll compare those setups to today’s market structure—ETFs, stablecoins, on-chain visibility, and deeper derivatives—to see what risks are genuinely lower, and which ones are still sitting there waiting for the wrong week.

One expectation up front: this is not a price call. It’s a framework for reading risk so headlines don’t do all your thinking for you.


The uncomfortable pattern behind most 70%+ crypto drawdowns

A simple three-part crash framework: leverage, liquidity, counterparty

Big drawdowns usually require a stack of fragilities. The recurring trio is:

  1. Leverage — borrowed exposure that can be forcibly closed.
    In crypto this often shows up as margin and derivatives (especially perpetual futures).
  2. Liquidity — whether you can sell size without moving the price a lot.
    Liquidity is what disappears first in a panic.
  3. Counterparty risk — the risk a “trusted” exchange/lender/fund can’t meet obligations.
    When trust breaks, even long-term holders can become forced sellers.

A key term you’ll see throughout:

  • Liquidation cascade: forced selling pushes price down → triggers more forced selling → repeats.

Why crypto sees extreme drawdowns more often than traditional markets

A few structural features make crypto more crash-prone:

  • Higher baseline volatility, which makes leverage easier to break.
  • Fragmented, shallow liquidity across venues and tokens (many markets look “active” until they’re stressed).
  • 24/7 trading, so drops can accelerate on weekends and off-hours when books are thinner.
  • A larger share of price-sensitive participants (traders, levered funds, some treasuries), especially outside BTC/ETH.

What this is (and isn’t)

We’re not trying to predict the next crash. We’re identifying the mechanics that turn “a bad week” into a generational drawdown.


Case Study #1 — 2018: The unwind after the ICO boom

2018 is the classic example of what happens when a boom is built on thin liquidity + relentless new supply + retail momentum.

What the market looked like going in

The 2017 cycle featured:

  • ICOs raising large sums (often in ETH/BTC).
  • A long tail of new tokens with limited depth.
  • Heavy retail participation chasing narratives and quick multiples.
  • Less mature institutional market-making than today.

One practical detail mattered: many projects that raised funds needed to pay expenses in fiat, which often meant selling crypto over time—extra supply pressure as the market weakened.

The dominant catalyst: reflexive deleveraging

When prices started falling, the unwind fed on itself:

  • Margin positions got liquidated.
  • Investors who were “up a lot” turned into sellers as the wealth effect reversed.
  • At times, miner stress can amplify downturns (revenues fall, some miners sell more to cover costs). The timing varies by episode, but the mechanism is real: economically forced participants add supply when prices are already falling.

How liquidity made it worse

A lot of 2018’s pain wasn’t just “people sold.” It was where they sold:

  • Many ICO-era tokens had shallow order books.
  • In stress, you discover an uncomfortable truth: an asset can be “tradable” (it has a price) but not liquid (you can’t sell size without crushing it).
  • Natural buyers step away and you get air pockets—the feeling of no bids.

Early warning signals that still translate

The vehicles change, but the warning signs rhyme:

  • Exploding issuance / supply growth (new tokens, unlocks, emissions).
  • Parabolic moves driven by marginal buyers.
  • Crowded positioning (today: high open interest + one-sided funding).
  • Narratives that justify any valuation because “this time is different.”

Case Study #2 — March 2020: The global liquidity shock

March 2020 is the reminder that crypto doesn’t need a crypto-native scandal to crash. Sometimes it just gets hit by the financial weather.

The trigger wasn’t crypto-native

The early COVID panic created a global dash for cash—a scramble for USD liquidity. In those regimes:

  • Correlations jump. “Diversifiers” suddenly move together.
  • Funds sell what they can, not what they want.
  • Crypto trades like a high-volatility risk asset.

How leverage unwound in hours

The speed came from leverage + market mechanics:

  • Levered long positions in perps/margin were liquidated quickly.
  • Cash-and-carry / basis trades (buy spot, short futures to capture a premium) can unwind aggressively when spreads move and financing tightens.
  • As positions are force-closed, they hit the market into thinning liquidity—fuel for a cascade.

Definitions, in plain English:

  • Funding rate (perps): a periodic payment between longs and shorts. Persistently positive funding often signals crowded longs.
  • Open interest (OI): total outstanding derivatives positions. High OI can mean leverage is building.
  • Basis: futures price minus spot. An unusually large basis can signal crowded carry/leverage trades.

Plumbing failures and feedback loops

In fast markets, the “plumbing” matters:

  • Bid-ask spreads widen.
  • Slippage increases (you get worse prices than expected).
  • Liquidity disappears exactly when everyone needs it.

(Some traders reported platform instability during that period across the industry. The useful takeaway isn’t blaming a single venue—it’s that operational stress rises when volatility spikes.)

What stabilized it

What stopped March 2020 (broadly) wasn’t a crypto-native rescue. It was macro:

  • Massive policy response and liquidity support from central banks.
  • A return of risk appetite as panic cooled.
  • Volatility subsided, allowing markets to function more normally again.

Signals to remember from March 2020:

  • Cross-asset correlation spikes
  • Rapid OI collapse
  • Funding flipping quickly
  • Spreads widening dramatically

Case Study #3 — 2022: Counterparty failures and trust collapse

2022 wasn’t “just a bear market.” It was a credit event.

The setup: yield chasing and opaque balance sheets

The 2020–2021 boom normalized “earn” products and high yields. Under the hood, much of that yield depended on:

  • Leverage
  • Collateral loops
  • Maturity mismatch (borrowing short, lending long/illiquid)
  • Rehypothecation (re-using the same collateral through a chain of borrowers and lenders)

The core issue: balance sheets were often opaque, so when stress hit, nobody knew who was solvent.

First domino: a major stablecoin/protocol failure (mechanism over trivia)

Early 2022 saw a major crypto-native failure involving a prominent stablecoin/protocol design. The sequencing matters for historians, but the mechanism is what risk readers should remember:

  • A perceived “stable” instrument fails → confidence breaks → liquidity evaporates → forced selling spreads.

Second domino: contagion through lenders, funds, and exchanges

As the year progressed, multiple centralized entities across lending, funds, and exchanges failed or entered distress (including widely known names like 3AC, Celsius, Voyager, and FTX).

Contagion followed a familiar path:

  1. Confidence breaks → withdrawals accelerate
  2. Lenders tighten → collateral haircuts rise
  3. Loans get called → entities sell what they can (often BTC/ETH) to raise liquidity
  4. Prices fall → more balance sheets go underwater → the cycle repeats

Why 2022 felt different

2022 had plenty of risk-off moments, but the dominant emotion was different:

  • Not “will price go down?”
  • But “is this counterparty solvent?”

That distinction matters because solvency fear causes runs—and runs create forced sellers even when fundamentals haven’t changed.

What stopped it (broadly):

  • Bankruptcies/closures forced deleveraging and clarified who survived.
  • The system reset at lower leverage, though not all risks vanished.

Signals to remember from 2022:

  • “Too good to be true” yields
  • Peg/depeg anxiety in stablecoins
  • Sudden, large exchange/lender outflows (with caveats)
  • Proof-of-reserves discussions—and their limitations

What repeats across 2018, 2020, 2022 (the crash recipe)

Different headlines. Same underlying recipe.

Leverage: where it hides

Leverage isn’t only “I borrowed on an exchange.” It can hide in:

  • Perpetual futures (high OI + one-sided funding)
  • Options structures that are effectively short volatility
  • Cross-collateral margin setups (one position blows up, everything is liquidated)
  • Off-exchange credit (OTC loans, private lending, structured yield)

The tell isn’t the product name. It’s the fragility: can positions be forcibly closed into a falling market?

Liquidity: “tradable” isn’t the same as “liquid”

In calm conditions, liquidity looks abundant. In panics:

  • Depth vanishes
  • Spreads widen
  • Markets gap

That’s why drawdowns overshoot: the market isn’t calmly “deciding” fair value—it’s searching for the level where forced selling finally meets real buyers.

Counterparties: when trusted entities become forced sellers

Systemic events often involve an entity that is:

  • Large
  • Trusted
  • Interconnected
  • Doing some form of maturity transformation (short-term liabilities, long/illiquid assets)

When that breaks, it’s not just reputational damage. It becomes mechanical selling pressure.

The accelerant: the narrative flip

When the narrative shifts from:

  • “Buy the dip”
    to
  • “Is it insolvent?”

…behavior changes. People withdraw first and ask questions later. That’s when a drawdown becomes nonlinear.

A quick comparison table (mechanisms, not trivia)

Period Primary trigger Dominant leverage Liquidity condition Dominant fear How it stabilized (broadly)
2018 Post-bubble unwind after ICO boom Margin/speculative positioning + supply overhang Thin, fragmented (esp. alts) “The boom was a mirage” Sellers exhausted + slow confidence rebuild
March 2020 Global dash-for-cash Derivatives + cross-asset deleveraging Liquidity evaporated fast “Need USD now” Macro liquidity response + risk appetite return
2022 Counterparty/credit failures Rehypothecation + credit chains Liquidity + trust crisis “Who’s solvent?” Bankruptcies/closures + forced deleveraging

What’s different now (and what that really means)

The biggest mistake is assuming “different” automatically means “safer.” Usually it means different trade-offs.

ETF flows and a new buyer class

Spot Bitcoin ETFs (where available) change access:

  • Easier exposure through regulated wrappers
  • A new class of buyers who may be more long-term than pure momentum traders

But there’s a catch:

  • ETFs can make BTC more flow-driven. Large creations/redemptions can matter in risk-off periods.
  • They may also strengthen the link to traditional risk sentiment.

Stablecoins: better rails, new concentration risk

Stablecoins are now the main settlement layer for crypto trading:

  • Faster movement of “cash-like” liquidity 24/7
  • Often smoother day-to-day market function

But they also introduce systemic concentration risk:

  • Issuer/reserve confidence
  • Banking rails and redemption pathways
  • Regulatory shocks
  • Peg stability under stress

On-chain transparency: more visibility, incomplete solvency info

On-chain analytics gives you visibility you don’t get in TradFi:

  • Wallet movements
  • Some reserve proof
  • Real-time settlement

But it doesn’t solve everything:

  • Liabilities are often off-chain
  • Related-party obligations can be hidden
  • Proof of reserves ≠ proof of solvency

Derivatives depth: better hedging and faster cascades

Derivatives are deeper than in earlier cycles:

  • Easier hedging for miners, funds, and sophisticated investors
  • More ways to express views without selling spot

But the same machinery can accelerate cascades:

  • Liquidation engines are fast
  • Crowded one-way positioning can unwind violently

More derivatives can mean more shock absorbers—or more explosives—depending on positioning.

Custody and counterparty fragmentation

Post-2022, many participants adapted:

  • More attention to custody and venue risk
  • Less blind trust in opaque yield

That likely reduces certain “single-giant-blowup” scenarios. But risk can migrate to:

  • Market makers / prime-broker-like setups
  • Offshore leverage
  • Bridges, DeFi protocols, and stablecoin rails

Which 70%+ risks are reduced vs still on the table

Reduced: some forms of opaque credit (vs peak 2021–2022)

Relative to the height of the yield bubble:

  • More skepticism around “risk-free” yield
  • Less dominance of the most aggressive rehypothecation structures
  • Better (still imperfect) risk management and transparency norms

Still present: sudden liquidity shocks (macro) and stablecoin confidence events

March 2020 can happen again in spirit:

  • Macro surprises
  • Dollar liquidity stress
  • Correlation spikes across risk assets

Stablecoin confidence events remain a tail risk because stablecoins sit in the middle of market plumbing.

Still present: hidden leverage

If you only watch exchange metrics, you can miss the real buildup:

  • OTC credit and private loans
  • Structured products embedding leverage/short-vol
  • Offshore derivatives activity

The theme: leverage doesn’t die—it relocates.

Altcoins vs BTC/ETH: why the math differs

When someone says “crypto could drop 70% again,” the first question should be: which crypto?

  • BTC/ETH generally have deeper liquidity, broader holder bases, and better hedging markets.
  • Many altcoins have thinner books and higher concentration (insiders, treasuries, emissions). In stress, they can gap down with surprisingly little selling.

A 70% drawdown in an alt can be a straightforward liquidity event. In BTC, it usually takes broader systemic stress.


A practical checklist: how to read “wipeout” headlines in real time

This isn’t about calling tops. It’s about recognizing when the recipe is forming: leverage + vanishing liquidity + counterparty fear.

Leverage dashboard: funding, open interest, liquidations, basis

Look for clusters, not single signals:

  • Funding rate persistently positive and elevated → crowded longs risk.
  • Open interest rising faster than spot volume/market depth → leverage building.
  • Liquidations spiking repeatedly → unstable positioning.
  • Basis unusually wide → crowded carry/leverage trades that can unwind.

If multiple are flashing, assume the market is more fragile than it looks.

Liquidity dashboard: spreads, depth, stablecoin flows, peg stress

Practical signals you can observe:

  • Bid-ask spreads widening on majors (BTC/ETH) → liquidity pulling back.
  • Order book depth thinning → air-pocket risk rises.
  • Stablecoin flows: surges onto exchanges can mean “dry powder,” but sharp outflows during panic can signal fear or de-risking.
  • Peg deviations (even small, persistent ones) can be early stress signals.

Counterparty dashboard: custody risk and the limits of “proof”

Ask boring questions when the market is euphoric—because you won’t have time later:

  • Is your exposure custodied across more than one venue?
  • Are you relying on yield from an entity you can’t underwrite?
  • If proof-of-reserves is published, do they address liabilities? (Often they can’t fully.)
  • Any stress signs: withdrawal delays, unusual incentives, abrupt policy changes?

Decision rules: de-risking, hedging, sizing, time horizon

Practical rules that reduce regret:

  • Size positions so you can survive volatility without being forced to sell.
  • If leverage indicators look overheated, consider:
    • trimming
    • moving to higher-quality collateral (BTC/ETH vs long-tail alts)
    • setting hedges (e.g., small protective puts) before panic pricing hits
  • Diversify custody if your portfolio size warrants it.
  • Avoid yield you can’t explain in one sentence.

FAQ (provided)

What usually triggers a 70%+ crypto drawdown?

Historically, the biggest drawdowns rarely come from a single headline. They typically require a stack of fragilities: (1) leverage that can be forcibly unwound (liquidations, margin calls), (2) liquidity that disappears when everyone sells at once, and/or (3) counterparty risk where a trusted lender/exchange/fund can’t meet obligations or becomes a forced seller.

Why was the 2018 crypto crash so severe?

2018 followed the ICO boom, when capital flowed into many thinly traded tokens and supply expanded quickly. As demand faded and prices fell, forced selling and reflexive deleveraging amplified declines—especially where liquidity was shallow and buyers stepped away.

What happened in the March 2020 Bitcoin crash?

March 2020 was mainly a global “dash for cash” liquidity shock. Crypto sold off alongside equities as investors raised dollars, cut risk, and met margin calls. Inside crypto, derivatives liquidations plus thin order books turned a fast drop into a cascade, even though the trigger wasn’t crypto-native.

Why did crypto crash in 2022 (LUNA/UST, lenders, FTX)?

2022 was dominated by counterparty and solvency fears after major failures across the crypto credit stack. When trust breaks, withdrawals accelerate, collateral haircuts rise, and even “good” collateral (like BTC/ETH) gets sold to meet redemptions—creating contagion that’s different from a normal risk-off move. (The exact sequencing varies; the key is the trust-to-forced-selling loop.)

What is a leverage unwind in plain English?

It’s when too many people have borrowed exposure (via margin or derivatives), and a price drop forces positions to close automatically. Those forced sales push price lower, which triggers more forced sales—often called a liquidation cascade.

What metrics signal leverage is getting dangerous?

Common warning lights include persistently one-sided perpetual futures funding, rising open interest relative to spot volume/market depth, frequent liquidation spikes, and an unusually large futures basis (often tied to crowded carry trades). No single metric predicts a crash, but clusters matter.

What’s the difference between “tradable” and “liquid” in a crash?

An asset can be tradable (it has a price) but not liquid (you can’t sell size without moving price a lot). In panics, order book depth vanishes, spreads widen, and markets gap—so even modest selling can cause outsized moves.

Do spot Bitcoin ETFs reduce crash risk or increase it?

Both effects can be true. ETFs can broaden access and bring a buyer base that may be more “sticky” than pure momentum traders. But they can also make BTC more flow-driven and more linked to traditional risk appetite—so large creation/redemption flows could amplify moves during sharp risk-off periods.

Are stablecoins a stabilizer or a systemic risk?

Stablecoins improve settlement and 24/7 liquidity—often stabilizing day-to-day trading. But they add concentration and confidence risk: if an issuer faces reserve, banking, liquidity, or regulatory stress, redemptions or depegs can become a market-wide shock.

Does on-chain transparency prevent another 2022-style collapse?

It helps, but it’s not a full solution. On-chain data can reveal some reserves and flows, yet it usually can’t show off-chain liabilities, hidden leverage, or related-party obligations. Proof-of-reserves can improve confidence, but “assets ≠ liabilities” remains the core limitation.

Where can leverage hide today if exchanges are more risk-managed?

Leverage can migrate into offshore venues, OTC credit, structured yield products, cross-margin setups, and options strategies that are effectively short volatility. When conditions flip, these can still unwind quickly.

Could BTC/ETH drop 70% again, and is that the same risk as altcoins?

BTC and ETH generally have deeper liquidity and broader holder bases than most altcoins, so their crash dynamics differ. Altcoins can experience air pockets more easily due to thinner books and higher concentration. The same shock can produce very different drawdowns across assets.


Conclusion: Crashes aren’t random—they rhyme

If you remember one thing from 2018, March 2020, and 2022, make it this:

70%+ drawdowns usually happen when leverage meets disappearing liquidity, and then trust breaks (or the other way around). The headline changes. The mechanism repeats.

The useful stance isn’t permanent bearishness. It’s conditional awareness: when leverage is crowded, liquidity is thin, and counterparties look shaky, you don’t need a crystal ball—you need a plan.

So the next time “crypto wipeout” trends, try this instead of doomscrolling:

  • Check leverage (funding, OI, liquidations, basis)
  • Check liquidity (spreads, depth, stablecoin/peg stress)
  • Check counterparty risk (custody concentration, transparency, withdrawal behavior)

Watch conditions, not price targets. That’s how you replace fear with context—and context with better decisions.
