How shorting works

The classic way is borrowing: you borrow a coin, sell it right away, and later buy it back to return it. If the price fell in between, you buy back for less than you sold and keep the difference. If the price rose, you must buy back at a higher price and take the loss, plus any borrowing fees.

In crypto, most shorting happens through perpetual futures. You post margin and open a short contract that gains when the price drops, without borrowing coins directly. These positions often use leverage and can be liquidated.

An example

Say you short 1,000 USDC worth of a coin at 50 USDC, without leverage, meaning a position of 20 coins. If the price drops to 40, buying back the 20 coins costs 800 USDC, so you gain 200 USDC before fees. If the price rises to 60, it costs 1,200 USDC, and you lose 200 USDC.

Why short positions matter

Shorting lets traders profit from or protect against falling prices. A common use is hedging: someone holding coins long term may open a short to reduce their exposure during a period of uncertainty. Short sellers also help markets price assets more accurately, because pessimistic views can be expressed, not just ignored.

Risks and common mistakes

A long position can lose at most 100 percent, because a price cannot fall below zero. A short has no such ceiling, because a price can keep rising. With leverage, a quick rally can liquidate a short in minutes. When many traders are short and the price rises, forced buying to close their positions can drive it even higher, a short squeeze. On perpetual futures, funding payments can also make holding a short expensive.

Frequently asked questions

Can you lose more than you invested when shorting?

In principle, yes, because prices can rise without limit. On most crypto derivatives platforms with isolated margin, liquidation closes the position before losses exceed the margin.

What is a short squeeze?

A rapid price rise that forces short sellers to buy back their positions or get liquidated, which pushes the price up further.

Is shorting allowed everywhere?

No. Access to derivatives and margin trading depends on your country's rules and the platform's policies, and some regions restrict it for retail users.
