Margin
Margin is the money you put up as collateral to open and keep a leveraged position. It lets you control a position larger than your own capital, but losses are taken from it, and if it runs too low, the position is liquidated.
How margin and leverage connect
With margin trading, the platform lets you take a position worth more than you deposit. The ratio between position size and your margin is the leverage. If you post 1,000 USDC of margin and open a 5,000 USDC position, you are using 5x leverage.
Two figures matter. Initial margin is what you need to open the position. Maintenance margin is the lower minimum you must keep to avoid liquidation. As the price moves against you, losses are deducted from your margin until it approaches that minimum.
An example
Say you post 1,000 USDC and go long 5,000 USDC worth of ETH at 5x. If ETH rises 10 percent, the position gains 500 USDC, a 50 percent return on your margin. If ETH falls 10 percent, you lose 500 USDC, half your margin. A fall of a bit less than 20 percent, depending on the platform's maintenance requirement and fees, triggers liquidation and most or all of your 1,000 USDC is gone.
Cross versus isolated margin
With isolated margin, each position has its own dedicated collateral. If it is liquidated, you lose that amount but nothing else. With cross margin, your whole account balance backs all open positions. That can keep a position alive longer, but one bad trade can drain the balance that was supporting everything else.
Some platforms also offer spot margin, where you borrow funds or coins to buy or sell, paying interest on the loan.
Risks to take seriously
Leverage magnifies losses exactly as much as gains, and crypto prices can move 10 percent or more in hours. Liquidation usually comes with extra fees. In fast markets, positions can be closed at worse prices than expected. Funding payments and borrowing interest eat into margin over time. Many beginners lose money not because their view was wrong, but because a short-term swing liquidated them first.

Frequently asked questions
What is a margin call?
It is a warning that your margin has fallen close to the maintenance level. In crypto, platforms often skip the call and liquidate automatically.
Can I lose more than my margin?
On most crypto platforms with isolated margin, losses are capped at the margin. With cross margin, more of your account is at risk, and terms vary by platform.
Is margin the same as leverage?
No. Margin is the collateral you deposit; leverage is how much larger the position is relative to that collateral.
