βοΈ Margin Trading Margin Trading
Trading with borrowed money. You put up some of your own funds as collateral (the "margin"), borrow the rest from an exchange, and open a position far bigger than your cash alone would allow.
π The simple version β a mortgage for a trade
Think of buying a house with a mortgage. A small down payment lets you control a much larger asset. If the house rises in value, your gain is large compared to that down payment. But if it drops sharply, you can owe more than it's worth and be forced to sell. Margin trading works the same way: your collateral is the down payment, the exchange's loan is the mortgage, and the coin is the house.
π’ Leverage β the multiplier
Leverage is the number that tells you how much bigger your position is than your own cash. With $1,000 at 10x leverage you control $10,000 of exposure. Crypto exchanges commonly offer anywhere from 2x up to 100x. The higher the leverage, the more a small price move swings your deposit.
| Your cash | Leverage | Position size | If price moves +10% |
|---|---|---|---|
| $1,000 | 2x | $2,000 | β +$200 (+20% on your cash) |
| $1,000 | 5x | $5,000 | β +$500 (+50% on your cash) |
| $1,000 | 10x | $10,000 | β +$1,000 (+100% on your cash) |
π The same table runs in reverse for losses. At 5x, a 10% drop is roughly a 50% loss on your deposit, before fees and interest.
𧱠Two margin numbers to know
| Term | What it means |
|---|---|
| πͺ Initial margin | The collateral you need just to open the position |
| π©Ί Maintenance margin | The minimum equity you must keep to hold the position open |
Borrowed funds also accrue interest the whole time the position is open, and that interest has to be repaid when you close.
π₯ Liquidation β the safety cut-off
If losses push your equity below the maintenance margin, the exchange force-closes your position so you can't lose more than the collateral you put up. This is liquidation. The higher your leverage, the smaller the price move needed to trigger it β a 100x position can be liquidated by a roughly 1% move against you.
π‘οΈ Isolated vs cross margin
| Mode | What's at risk | Good for |
|---|---|---|
| π Isolated margin | Only the collateral assigned to that one position | Beginners β losses are contained |
| π Cross margin | Your whole account balance, shared as one pool | Bigger leverage, but a bad trade can liquidate everything |
π¨ Things beginners should know
- π Losses are magnified too β Leverage cuts both ways; the gain math and the loss math are identical
- πΈ Interest adds up β The borrowed funds cost interest for as long as the position stays open
- π₯ Liquidation is real β Higher leverage means the price has less room to move before you're wiped out
- π§ Start with isolated margin β It caps your risk to one position instead of your entire account
β FAQ
- Is margin trading the same as futures trading?
- They both use leverage, but they're not the same. Margin trading borrows money to buy the actual coin, so you really own it. Futures are contracts that bet on a price without ever owning the underlying coin.
- Does leverage only multiply my profits?
- No. It multiplies losses by exactly the same amount. At 5x, a 10% drop in price wipes out about 50% of the money you put in, and a large enough drop can liquidate your whole collateral.
- Can I lose more than the money I put in?
- Liquidation is designed to stop that: when your equity falls below the maintenance margin, the exchange force-closes the position so your loss is capped at your collateral. With isolated margin only that one position's collateral is at risk; with cross margin your whole account balance is on the line.
