Long and short in crypto trading, explained
A long gains when the price rises; a short gains when it falls. See how both work with one simple USDT example, including losses, closing and liquidation.
Going long in crypto means opening a position that gains when the price rises. Going short means opening a position that gains when the price falls. Both can lose money if the price moves the other way.
If you have seen Buy / Long and Sell / Short in a futures app, those buttons choose your position's direction. A long buys first and sells later. A short sells first and buys back later. In futures, you trade a contract, so you do not need to own the coin to open a short.
What is the difference between long and short in crypto?
| Action or price move | Long | Short |
|---|---|---|
| Open the position | Buy | Sell |
| Price rises | Gain | Loss |
| Price falls | Loss | Gain |
| Close the position | Sell | Buy back |
These gains and losses describe the price movement before fees and funding. Long and short describe direction, not how long you hold a trade.
Buying a coin outright is a spot purchase: you own the coin. A futures position gives you exposure to its price through a contract. Perpetual futures, often called perps, have no expiry date, but you still need enough margin to keep the position open.
How can a short make money when the price falls?
The order of the trade is reversed: sell first, buy back for less. The difference is your profit before costs. If buying back costs more than the opening sale price, the difference is a loss.
A futures short works through a contract instead. You put up collateral, called margin, rather than borrowing and selling coins yourself. With USDT-settled futures, the price difference is settled in USDT.
Selling coins you already own simply reduces your holding. Opening a futures short creates a position that gains from a subsequent price fall.
Long and short profit and loss: one worked example
Suppose a SOL futures contract trades at 100 USDT, and you open a position representing 10 SOL. Its entry value is 1,000 USDT. These are hypothetical round numbers, not current prices or a prediction.
Compare a long and a short of that same size:
- If you close when the price reaches 110 USDT: the long gains (110 − 100) × 10 = 100 USDT. The short loses (100 − 110) × 10 = −100 USDT.
- If you close when the price reaches 90 USDT: the long loses (90 − 100) × 10 = −100 USDT. The short gains (100 − 90) × 10 = 100 USDT.
For these USDT futures, the calculations are:
- Long P&L = (exit price − entry price) × coin quantity.
- Short P&L = (entry price − exit price) × coin quantity.
P&L means profit and loss. While the position is open, its price gain or loss is unrealised and can change. Closing it realises that result. Trading fees and any funding paid or received also affect the final amount.
What are the risks of going long or short?
A long loses as the price falls. A short loses as the price rises. A price cannot fall below zero, but there is no equivalent ceiling on how high it can rise. A short's theoretical price loss therefore has no fixed upper limit if the position stays open. A margined futures position can be liquidated before that loss keeps growing.
Leverage makes losses larger relative to your margin for both directions. In the example above, a 1,000 USDT position at 5x needs 200 USDT of initial margin before costs. A 100 USDT loss is half that margin. For a fixed position size, changing leverage changes the margin needed, not the USDT profit or loss from the same price move.
Liquidation is the forced closing of a position when its collateral no longer meets the minimum requirement, called maintenance margin. A leveraged long can be liquidated after a price fall; a leveraged short after a price rise. Higher leverage leaves less margin relative to the position, bringing liquidation closer.
In Cryptathon, isolated margin limits the position's liquidation loss to the margin assigned to it. All of this money is virtual. On real platforms, margin rules vary.
Our guides to leverage in crypto trading and liquidation in crypto futures explain the relationship between position size, margin and forced closing.
How do you close a long or short?
Close a long by selling the same quantity. Close a short by buying back the same quantity. Closing only part reduces the position and leaves the rest open.
Use the position's close control or a reduce-only closing order where available. An ordinary opposite-direction order can behave differently depending on the platform's position mode, so check that it closes the existing position.
In Cryptathon, there is one net position per market. With a long open, the Sell button becomes Close long for the full size or Reduce long for part. With a short open, the Buy button becomes Close short or Reduce short. Buying back a short closes that exposure.

Practise going long and short with virtual money
Cryptathon is a crypto paper trading game for Android and the browser. New players start with 10,000 virtual USDT to practise Bitcoin, Ethereum and Solana USDT perpetual futures. All money is virtual. Nothing can be withdrawn.
- With no position open in a market, tap Buy / Long. Note the entry price, size and leverage shown in Positions.
- Observe how the virtual P&L changes with price, then use Close long.
- With that market's position closed, tap Sell / Short. Compare its P&L with the short formula, then buy back using Close short.
Practise in Cryptathon on Google Play or in your browser. Our guide to crypto paper trading explains practising without risking real money.

Frequently asked questions
What do long and short mean in crypto trading?
A long is a position that gains when the price rises and loses when it falls. A short gains when the price falls and loses when it rises. These directions describe price profit and loss before trading costs.
Can I short crypto without owning it?
Yes, through a futures contract. You provide margin and sell to open the short, then buy back to close it. You do not need to own the underlying coin. This differs from a short sale that involves borrowing the asset.
Does Sell / Short always open a short?
No. It depends on your existing position and the app's position mode. In Cryptathon, Sell / Short opens a short when you have no position in that market. If you already hold a long, a sell up to its size closes or reduces that long.
Is a long safer than a short?
Both can lose money, and leverage can cause liquidation in either direction. A short's theoretical loss grows without a fixed price ceiling as the price rises. A leveraged long can still lose its position margin after a price fall.
