Margin trading lets you open a position bigger than your account using funds borrowed from the exchange. But leverage doesn't play favorites: it multiplies profits and losses alike. And if the market moves sharply against you, the exchange will close the trade for you. In this lesson, we'll cover how margin works, what the liquidation price and funding are, how cross and isolated modes differ, and which rules keep you from blowing up your account in a single day.

Key takeaways
  • Leverage multiplies both profits and losses: at 10x, a 10% price move against you practically wipes out your margin.
  • Liquidation happens before you hit zero: the exchange closes the position once your margin falls to the maintenance level.
  • Isolated margin limits the risk to a single trade, while cross margin puts your whole balance on the line.
  • Position size is calculated from the loss you can accept at your stop-loss, not from the maximum leverage available.

How margin trading works

On spot, you pay for your coins in full. In a margin trade, you put up only part of the amount, called margin or collateral, and the exchange covers the rest. The ratio of position size to margin is your leverage. Put up 100 USDT of margin at 5x leverage, and you control a 500 USDT position.

In crypto, margin trading comes in two forms. The first is spot margin: you borrow real money or coins from the exchange and pay interest on the loan. The second is perpetual futures, or perps. Here you don't buy the coin itself but a contract on its price, and instead of interest you periodically pay or receive funding. On major exchanges, the lion's share of leveraged trading happens in perps.

Leverage lets you open both long positions, betting on a rise, and short positions, betting on a drop. You can't short without margin: the only way to sell something you don't own is to borrow it or open a contract.

Term · Initial and maintenance margin

Initial margin is the collateral the exchange locks up when you open a trade. Maintenance margin is the minimum collateral level; once you drop below it, liquidation kicks in.

Leverage multiplies losses too

Leverage doesn't change how the market moves; it changes how much that move weighs on your account. Bitcoin up 2%? A spot position shows the same 2%, while a 10x position shows about 20% on your margin before fees. A drop works the same way in reverse: a 2% price decline turns into roughly a 20% hit to your collateral.

That gives you a simple rule of thumb: at N times leverage, a price move of about 100/N percent against you wipes out all your margin. In practice, liquidation comes sooner, because the exchange keeps a buffer for maintenance margin and fees.

For many cryptocurrencies, daily swings of a few percent are normal, and small caps can move far more. With high leverage, that kind of noise can easily knock you out of a position even if you called the overall direction right. The market ends up going exactly where you expected, just without you.

Leverage amplifies not only the numbers in your account but your emotions too. When your balance jumps with every tick, it's hard to stick to the plan: you want to grab profits too early and hold on to a losing trade too long, hoping for a reversal. This side of trading is covered in detail in the lesson on trading psychology.

Leverage Position with 100 USDT margin Move against you that wipes out the margin (approx., excluding fees)
2x 200 USDT 50%
5x 500 USDT 20%
10x 1,000 USDT 10%
20x 2,000 USDT 5%
50x 5,000 USDT 2%
100x 10,000 USDT 1%

Important · Maximum leverage isn't a recommendation

Exchanges offer leverage of 100x and higher, but that's a technical ceiling, not a sensible level. The higher the leverage, the closer your liquidation price sits to your entry.

Liquidation and the liquidation price

When losses eat your margin down to the maintenance level, the exchange forcibly closes your position. That's liquidation. In traditional finance, a broker will sometimes send a margin call first, asking you to top up your account. Crypto exchanges usually close the position automatically, and the warning, if there is one at all, may come just minutes or even seconds before.

The exchange shows you the liquidation price before you even open the trade. It depends on your leverage, margin mode, position size and the maintenance margin rate, which on many exchanges goes up as your position gets bigger. Checking this number before every entry is the first habit worth building.

Keep in mind that most exchanges calculate liquidation not from the last traded price but from the mark price, which is based on an index across several platforms. This protects you from getting liquidated by a random spike on one exchange, but the price on your chart and the price used for liquidation can differ slightly.

When you're liquidated, you lose the position's margin, and on many exchanges whatever is left of it, plus a liquidation fee, goes into the insurance fund. In sharp moves, liquidations set each other off: forced selling pushes the price lower and hits the next positions in line. Cascades like this explain many of the long wicks you see on charts, after which the price quickly bounces back.

Isolated vs cross margin, and funding

In isolated mode, each position has its own margin: if it gets liquidated, you lose only that, and the rest of your balance stays untouched. In cross mode, your entire free balance serves as collateral: the position survives longer, but if it does get liquidated, the loss can be far bigger than you planned for.

If you're just starting out with leverage, isolated mode is the smarter choice, because you know your maximum loss on the trade in advance. Cross margin takes discipline and an understanding of how positions affect each other, and it's more often used for hedging, when some positions offset others.

Perps have funding: regular payments between longs and shorts that keep the contract price close to spot. When the market is skewed toward longs, longs pay shorts, and vice versa. Settlement usually happens every few hours, and if you hold a position for a long time, funding can take a noticeable bite out of your result.

Say the funding rate is 0.01% per period with three settlements a day: a 1,000 USDT position will pay or receive about 0.3 USDT a day. Sounds trivial, but during hype phases the rate can be several times higher, and it's charged on the full leveraged position size, not just your margin.

Tip · Mode first, leverage second

Before you open a trade, check which margin mode is selected by default. On some exchanges it's cross margin, and one bad position can drag down your whole account.

How to size a position and protect your account

Experienced traders size positions based on risk, not leverage. First they decide what share of the account they're willing to lose on the trade, then they set a stop-loss where the trade idea stops working, and only then do they calculate the size. With this approach, leverage is simply a way to avoid parking extra collateral on the exchange.

Say your account is 1,000 USDT, your acceptable risk is 1%, which is 10 USDT, and your stop-loss is 2% below entry. That gives you a 500 USDT position: if the stop is hit, you lose about 10 USDT plus fees. You can open it at 5x leverage with 100 USDT of margin, and the liquidation price will sit well beyond your stop. This logic is covered in more depth in our complete risk management guide.

Finally, there are external risks. In some countries, margin trading and derivatives are restricted or banned for retail traders, and exchanges change their terms from time to time. Before you open this kind of account, check what's allowed in your jurisdiction.

  1. Decide your acceptable risk per trade as a percentage of your account
  2. Find your stop-loss level on the chart, not at a convenient round number
  3. Calculate your position size: acceptable loss divided by the distance to your stop in percent
  4. Pick the lowest leverage that gives you enough margin, and use isolated mode
  5. Check that the liquidation price is well beyond your stop-loss
  6. Account for fees and funding if you hold the position for more than a few hours

Important · Don't rescue a losing position

Adding margin to a losing trade pushes liquidation further away but makes your potential loss bigger. If your stop was hit, the idea didn't play out: close the trade and review it.

Lesson task

On a BuyCrypt demo account, set up a BTC/USDT futures position for the same amount, say 500 virtual USDT, first with 2x leverage and then with 10x. For each version, write down the margin and the liquidation price the app shows. You'll see that the position size and the loss at your stop are the same, only the collateral changes, while the liquidation price at 10x ends up several times closer to your entry.

FAQ

What leverage should a beginner use?

Start with minimal leverage, or stick to spot. But it's not really about the leverage itself: what matters is how much risk you take per trade and whether your stop-loss is in place from the start.

Can I lose more than I put in?

In isolated mode, your loss is usually limited to the position's margin; in cross mode, to the balance of your whole account. If a liquidation loss turns out bigger than the margin, the difference is usually covered by the exchange's insurance fund, but every platform has its own terms, so read its rules.

How is spot margin different from futures?

With spot margin, you borrow real money or coins and pay interest on the loan. With futures, you trade a contract on the price and pay or receive funding. The liquidation mechanics are similar either way.

Does a stop-loss protect me from liquidation?

Yes, as long as it sits closer to your entry than the liquidation price. In a sharp move, a stop can fill with slippage, but that's almost always better than losing your entire margin.
