What Is a Margin Call in Crypto?

A margin call is the market's way of tapping you on the shoulder before things go wrong. Understanding it helps you act before the exchange acts for you.

What triggers it

When you open a leveraged position you post margin. As price moves against you, your losses eat into that margin. When it falls close to the maintenance level the exchange requires, you get a margin call — a warning that you're near forced closure.

Margin call vs liquidation

They're not the same. A margin call is the warning; liquidation is what happens next if you do nothing. In fast crypto markets the gap between the two can be seconds, so don't rely on having time to react.

Your options when called

• Add margin — top up collateral to push liquidation further away.
• Reduce the position — close part of it to lower risk.
• Close it — take the controlled loss and reset.

How to avoid them entirely

Use lower leverage, keep a margin buffer, size by risk, and set a stop-loss inside your liquidation price. Do that and you'll rarely, if ever, see a margin call.
