The basic idea
Leverage means controlling a position larger than the money you put up. The money you put up is the margin, a deposit that acts as collateral. The exchange or broker effectively lends the rest. The ratio between position size and margin is the leverage.
This is the core of margin trading. It does not change what the asset does. It changes how much of your own money each price move affects. The examples below use round, made-up numbers to show the mechanics. They are illustrations, not forecasts, and they ignore fees and funding to keep the arithmetic clear.
Example 1: no leverage
Suppose you buy $1,000 of a coin with your own money. If the price rises 10%, your holding is worth $1,100, a gain of $100 or 10%. If it falls 10%, it is worth $900, a loss of $100 or 10%. Your gain or loss as a percentage of your money equals the price move.
Example 2: 10x leverage
Now suppose you post $1,000 of margin and open a $10,000 long position. That is 10x leverage.
- Price rises 5%: the position gains $500, which is 50% of your $1,000 margin.
- Price falls 5%: the position loses $500, which is 50% of your margin.
- Price falls 10%: the position loses $1,000, which is 100% of your margin.
So with 10x, a move that would feel modest on an unleveraged holding either adds half to your money or removes half of it. A fall of around 10% would remove all of it.
Example 3: 2x and 20x for comparison
At 2x, $1,000 controls $2,000. A 10% fall costs $200, which is 20% of your margin. The position survives a large drop.
At 20x, $1,000 controls $20,000. A 5% fall costs $1,000, which is 100% of your margin. A move that happens often in crypto, because of price volatility, can end the position entirely.
A rough rule: the percentage move that would wipe out margin is about 100 divided by the leverage. At 10x that is about 10%, at 20x about 5%, at 50x about 2%. Real thresholds are closer than this, as the next section explains.
Maintenance margin and the liquidation price
Exchanges do not wait until your margin is entirely gone. They require a minimum cushion, the maintenance margin, to keep a position open. If losses eat the margin down to that level, the exchange closes the position automatically. This is a liquidation.
Take the 10x example and assume, purely for illustration, that maintenance margin is 0.5% of the position, or $50 on $10,000. Liquidation then happens when losses reach about $950, which is a 9.5% fall rather than 10%. Fees and the exchange’s own liquidation method can move this further.
Real rules vary by venue, product and position size. Always read the specific terms rather than assuming the figures above.
Shorting works the same way in reverse
A short position profits when the price falls. With the same $1,000 margin and $10,000 short at 10x, a 5% fall gains $500 and a 5% rise loses $500. A 10% rise would wipe out the margin. Shorts therefore also face liquidation, which is relevant to what happens in a short squeeze.
Why losses can exceed intuition
Several details make leveraged outcomes worse than the simple examples suggest.
- Gaps and slippage. In a fast market the price can jump past your liquidation level. The closing trade fills at whatever is available, and price slippage can leave a shortfall beyond your margin on some venues. Thin market liquidity makes this more likely.
- Funding and fees. Perpetual contracts charge or pay a funding rate, and every trade has fees, both of which eat into margin over time.
- Cross versus isolated margin. With isolated margin, only the collateral assigned to one position is at risk. With cross margin, the whole account balance can be pulled in to support it, so a single position can drain more than you intended.
- Compounding of mistakes. After a loss, people sometimes add leverage to win it back. This tends to deepen the damage and is a classic emotional discipline problem.
Gains are real, but so is the asymmetry
Leverage does magnify gains. That is why it is attractive, and why it can look like a shortcut. But the two directions are not symmetrical in their consequences. A leveraged gain is capped by how far the price moves in your favour, while a leveraged loss is capped by your margin, and reaching that cap is much more likely at high leverage. A position can also be liquidated by a brief spike, then the price may return to where you wanted it, with you already out.
Practical risk notes
- Lower leverage leaves more room for ordinary price swings. High leverage leaves very little.
- Many experienced traders choose their position sizing first and treat leverage as a tool for efficiency, not a way to increase size beyond what they can afford to lose.
- Only money you can afford to lose entirely should be used. Outcomes are uncertain, past results do not predict future results, and many people lose their entire margin.
