A new piece of information may start the move, but leverage, forced liquidations, disappearing liquidity and exchange failures can accelerate it. During the October 10, 2025 episode, Bitcoin fell more than 14% intraday, while SIFMA reported that about $19 billion in leveraged positions were liquidated almost instantly. Some traders could not place orders or manage collateral because platforms suffered technical failures.
The practical lesson is that price risk, liquidation risk, access risk and custody risk are separate problems. You need a plan for each one before a volatile market opens, not after your position is already in danger.

What makes a crypto crash happen so quickly?
A crash usually begins with a repricing: traders collectively decide that an asset is worth less because of new information, changing expectations, a macroeconomic shock or a loss of confidence. The first decline can then trigger mechanical selling that has little to do with a fresh change in fundamentals.

With leverage, a trader controls a position larger than the cash posted as collateral. A small percentage move in the underlying asset therefore creates a much larger percentage gain or loss on the trader’s margin. When the account no longer meets a venue’s maintenance-margin requirement, the trader may have to add collateral or the platform may close the position.
The Commodity Futures Trading Commission (CFTC) warns that leverage amplifies both gains and losses. Depending on the product and venue, losses can exceed the amount initially deposited. One liquidation can push the market lower, causing other leveraged positions to fail and creating a cascade.
Liquidity disappears when everyone needs to sell
Liquidity is the amount of buy and sell interest available near the current price. In calm conditions, a large order may be absorbed with a modest price change. During a panic, market makers can widen spreads, reduce order size or withdraw temporarily. A sell order then moves through several price levels, producing a larger decline than the same order would have caused earlier.
Price marks can accelerate liquidations
Derivatives platforms generally use a mark price, index price or another reference to determine whether a position should be liquidated. The exact formula is venue-specific. SIFMA reported that, during the October 2025 crash, some platforms used in-house price marks that diverged from prices on other markets. Those differences could trigger liquidations that would not have occurred under another reference price. Once those positions were forcibly closed, thinner liquidity caused further losses.
Technical failures add an access crisis
A price crash can overload APIs, matching engines, mobile apps, identity systems and collateral-transfer processes. If an exchange is unavailable, a trader may be unable to cancel an order, add margin, reduce a position or withdraw funds. SIFMA said widespread technical failures during the October 10 event left traders unable to execute trades or protect positions. An outage does not stop the wider market from moving.
What happened on October 10, 2025?
The event is a useful case study, but its numbers are not a typical crash average. SIFMA’s 2025 account describes a rapid, leveraged sell-off with technical problems across exchanges.
| Measure | Reported detail | How to interpret it |
|---|---|---|
| Bitcoin move | More than 14% intraday decline | An event-specific observation, not a forecast or universal crash size |
| Leveraged liquidations | About $19 billion in positions liquidated almost instantly | A reported total for that episode, not a normal daily amount |
| Market conditions | Liquidity withdrew and forced selling snowballed | Thin order books can magnify otherwise manageable orders |
| Platform operation | Some exchanges suffered technical failures | Traders could lose the ability to trade or manage collateral while prices continued changing |
No reliable universal percentage or duration defines a “crypto crash.” The size and length depend on the asset, venue, market depth, leverage concentration and the information that caused the repricing.
How liquidation works, and why rules differ by exchange
Liquidation is the forced reduction or closure of a leveraged position when the account falls below a required margin level. It is not a single industry-wide process. Each platform sets its own thresholds, calculations and protections.
The terms to check before opening a position
- Initial margin: The collateral required to open the position.
- Maintenance margin: The minimum equity that must remain for the position to stay open.
- Mark price: The reference price used to calculate unrealized profit, loss and liquidation conditions.
- Liquidation fee: A charge that may apply when the platform closes the position.
- Insurance fund: A venue reserve that may absorb certain losses after liquidation, subject to that venue’s rules.
- Auto-deleveraging: A process that can reduce profitable or opposing traders’ positions if the platform cannot contain losses through its normal protections.
- Partial versus full liquidation: Some systems close only enough of a position to restore margin; others can close the entire position.
Read the current contract specifications, margin schedule, fee page and liquidation policy for the exact venue you intend to use. A liquidation price shown in an interface is an estimate based on that platform’s assumptions; fees, funding, mark-price changes and other open positions can move the actual trigger.
A simple, hypothetical example
Suppose a trader posts $1,000 and opens a $5,000 position, using 5× leverage. A 10% adverse move represents a $500 loss before fees and funding, consuming half of the posted margin. A larger move, a sudden gap or additional costs can bring the account below maintenance margin. The example is illustrative only: real liquidation levels depend on the instrument, margin mode, mark price and venue rules.
How can you reduce the chance of liquidation?
No technique eliminates liquidation risk, but several controls make a position less fragile.
- Start with the venue’s rules. Locate the current margin, mark-price, liquidation, funding and fee documentation. Confirm whether the account uses isolated or cross margin and how other positions affect available collateral.
- Use a position size that can survive a large move. Calculate the loss from a severe but plausible adverse move before entering. Smaller notional exposure leaves more room between the entry price and the liquidation threshold.
- Keep leverage low or avoid it. Leverage does not make an asset safer; it reduces the price movement needed to exhaust collateral.
- Maintain a separate cash buffer. Do not commit every available dollar as trading collateral. A reserve can cover a margin requirement or ordinary living expenses without forcing an emergency transfer.
- Know the venue’s reduction process. Determine whether liquidation is partial or full, which fees apply, and whether an insurance fund or auto-deleveraging system can affect the final result.
- Do not increase leverage during an outage. If orders, collateral transfers or account data are unreliable, adding exposure removes your ability to manage the risk you are taking.
- Set an exit plan before entry. A voluntary stop or position-reduction rule can act before the platform’s forced liquidation threshold, although stop orders are not guaranteed to execute at the intended price during a fast market.
Even a carefully sized position can be affected by a gap, an index discrepancy, a platform outage or a sudden fee. Treat these controls as risk reduction, not guarantees.

Can leverage make you lose more than you deposited?
It can. The CFTC specifically warns that leveraged virtual-currency trading can produce losses greater than the initial investment. Whether a trader actually owes more depends on the product’s contract, margin agreement and liquidation process. Some venues advertise protections that limit a negative balance; others may pursue a deficit or reserve contractual rights to do so.
Before trading, read the customer agreement and determine:
- Whether the account can become negative after liquidation.
- Whether cross-margin positions can draw on other balances.
- How fees, funding payments and liquidation charges are collected.
- What happens if the insurance fund is insufficient.
- Whether auto-deleveraging can reduce an otherwise profitable position.
If the documentation is unclear, assume the exposure is not fully understood and do not fund the position.
What should you do if an exchange goes down during a crash?
An outage creates an execution and access problem, not a pause in market risk. Follow a written checklist and preserve evidence.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Check official status information. Use the platform’s published status page, incident notice or verified account. Do not rely on screenshots or unsolicited messages.
- Record the event. Note the UTC time, error messages, affected products, open-order IDs, position IDs and account balances. Save screenshots and transaction records where possible.
- Do not assume the price will reverse. You may be unable to close, hedge or add collateral, while other markets continue trading.
- Protect account credentials. Ignore messages asking for a password, one-time code, seed phrase or emergency transfer. The CFTC warns that hacking, phishing and exchange scams are recurring risks.
- Wait for a confirmed restoration. Repeatedly submitting orders during a degraded service can create duplicates if the system later processes queued requests.
- Reconcile everything when access returns. Compare balances, fills, fees, funding payments, open orders, deposits, withdrawals and liquidation events with your own records.
- Contact support through the official channel. Include timestamps and identifiers, but never send a recovery phrase or private key.
- Pause new trading until the record is complete. A missing fill, duplicate order or incorrect fee can distort the risk of every subsequent trade.
Withdrawal rights, compensation policies, uptime promises and liquidation procedures vary by platform and can change. An outage does not automatically create a right to reimbursement.

This is an operational choice, not a guarantee against losses. Exchange custody is convenient for active trading but depends on the platform’s systems and controls. Hardware-wallet self-custody removes some exchange dependence, while moving responsibility for the private keys and recovery phrase to you.
| Consideration | Exchange custody | Hardware-wallet self-custody |
|---|---|---|
| Access | Convenient account interface, dependent on uptime, login controls and withdrawals | Keys can be used without exchange uptime; the device and recovery phrase must be protected |
| Main failure mode | Outage, withdrawal freeze, cyber incident or platform failure | Lost or exposed recovery phrase, phishing, device failure or user error |
| Trading | Immediate venue trading when the platform is operating | Usually requires transferring assets to a venue, adding time and network fees |
| Responsibility | The platform operates custody processes and account recovery | You control the keys and are responsible for backups and recovery |
A hardware wallet can reduce dependence on an exchange and may be appropriate for assets you do not need to trade immediately. It cannot prevent the asset’s market price from falling. Conversely, leaving funds on a venue may simplify trading but exposes those funds to the platform’s operational, withdrawal and solvency risks. The CFTC advises researching both platforms and digital wallets before providing money or sensitive information.
What does the 2026 regulatory clarification change?
In a March 17, 2026 release, the Securities and Exchange Commission and CFTC described an interpretation clarifying how federal securities laws apply to certain crypto assets and transactions. That classification context may affect legal treatment, disclosures and oversight, but it does not remove volatility, leverage, custody or outage risk. A token’s regulatory classification is not a promise that its price is stable or that a platform will always be available.

A practical crash-preparation plan
Before opening a position
- Identify the exact product, venue, margin mode and liquidation formula.
- Write down the maximum loss you can afford and keep that amount separate from essential funds.
- Test login, two-factor authentication, withdrawal settings and backup contact methods during normal conditions.
- Save official status-page and support links so you can recognize fraudulent lookalikes.
While the market is moving sharply
- Reduce exposure rather than adding leverage to recover a loss.
- Check mark price, available margin, open orders and funding costs, not just the headline chart.
- Expect wider spreads and partial fills; avoid assuming a stop will execute at its trigger price.
- If the venue is degraded, stop submitting repeated orders and document the state of the account.
After the move
- Reconcile every fill, fee, transfer and liquidation with independent records.
- Review whether the venue’s price mark and liquidation treatment matched its published rules.
- Only resume trading after you understand any discrepancy and have restored a cash buffer.
Bottom line
Crypto crashes become violent when a rapid repricing meets crowded leverage, forced selling, thin liquidity and unreliable access. Use the venue’s current rules, size positions so a large move does not exhaust your margin, keep emergency cash outside the trading account and prepare for an outage. There is no guaranteed strategy; the CFTC’s core advice is to speculate only with money you can afford to lose.
