What Are Crypto Perpetuals? A Beginner's Guide to Futures Trading

Crypto perpetuals guide giant gold coin candlestick chart futures trading

A crypto perpetual, often called a "perp", is a futures contract with no expiry date that lets you bet on the price of a coin going up or down without ever owning the coin itself. You can hold it for minutes or for months, as long as you keep enough margin in your account. If you have ever wondered how traders make money when prices fall, or why a small price move can wipe out an account, this guide explains perpetuals in simple words.

Key points:

A perpetual is a futures contract with no expiry date, kept close to the spot price by a funding rate.
Leverage lets a small margin control a much bigger position, so both gains and losses are multiplied.
If your margin falls too low, the exchange closes your position automatically in a liquidation.

What is a futures contract in simple words?

A futures contract is an agreement about a future price. Two sides agree on the price of something today, and settle the difference later. In crypto, that settlement is almost always in cash, which means you never receive the actual coin. Instead, you receive or pay the difference between the price when you opened the position and the price when you closed it.

Suppose Bitcoin is trading at $80,000. If you open a long position, you are betting the price will rise, and you gain when it rises. If you open a short position, you are betting the price will fall, and you gain when it drops. Long means you expect up, short means you expect down.

What makes a perpetual different from a normal future?

A normal futures contract has an expiry date, a fixed day when the contract ends and settles. As that day gets closer, the contract price is pulled toward the real market price, because the two must meet on settlement day.

A perpetual has no expiry date at all. With no settlement day to force the price back to the spot market, the contract needs another anchor. That anchor is the funding rate, a small payment that passes between traders at regular intervals, and it keeps the perpetual price close to the real price of the coin.

How does the funding rate work?

The funding rate is a payment exchanged directly between traders, not a fee paid to the exchange. On most large venues, it is calculated every eight hours, although some venues do it every hour. The exchange looks at how far the perpetual price sits from the spot price, the real market price of the coin, and sets a rate from that gap.

When the perpetual trades above the spot price, traders who are long pay traders who are short, which encourages selling and pushes the price back down. When it trades below the spot price, the payment runs the other way, and shorts pay longs.

One detail matters a lot for beginners: Funding is charged on your whole position, not just on your margin. A rate that looks tiny, such as 0.01% every eight hours, adds up fast with leverage, because it is paid out of the margin you deposited. A position can slowly lose money to funding even on days when the price barely moves.

What is leverage, and why is it dangerous?

Leverage is borrowed buying power. When you post margin, the collateral or deposit you put up, the exchange lets you control a position many times larger than that margin. At 10x leverage, $100 of margin controls a $1,000 position, so every 1% move in the coin price is worth $10, which is 10% of your margin.

That multiplication works in both directions, and that is the danger. A 10% rise doubles your margin, but a 10% fall wipes it out completely. Leverage does not change how much the market moves, it only changes how much each move is worth to you. Some venues offer leverage as high as 100x, but at 100x, a move of just 1% against you is enough to lose your whole margin.

What is liquidation?

Liquidation is the automatic closing of your position by the exchange when your margin falls too low. Every position has a liquidation price, the price at which your remaining margin can no longer support the position. When the market reaches that price, the exchange closes your trade for you, and you lose most or all of the margin you posted.

Exchanges do not liquidate against the last traded price, which could be moved by a single thin trade. Instead, they use a mark price, a fair-value figure worked out from the spot market across several exchanges. Liquidation is also final in one important way: Once your position is closed, it stays closed, so if the price bounces back five minutes later, you do not get your position or your margin back.

How are perpetuals different from buying crypto on the spot market?

Buying on the spot market means buying the actual coin, and you own it until you sell it. There is no expiry, no funding rate, and no liquidation price. If the price falls, your holding is worth less, but nobody forces you to sell, and you can wait for a recovery. Your loss is limited to what you paid.

A perpetual is different in four ways. First, you never own the coin, you only hold a contract on its price. Second, there is no expiry, but you pay or receive funding the whole time you hold it. Third, leverage multiplies your gains and your losses. Fourth, liquidation can close your position at the worst moment, even if the price recovers later.

Who uses perpetuals, and should a beginner use them?

Perpetuals are used by two main groups. Speculators bet on price direction, up or down, with leverage. Hedgers protect an existing holding. For example, a miner who holds Bitcoin might open a short perpetual to offset a possible price fall, so a drop in the coin is balanced by a gain on the contract. Both groups accept the same risks, and both can be liquidated.

For a beginner, the honest answer is to learn spot trading first. Understand how to buy, store, and sell a coin before adding leverage, funding, and liquidation to the mix. If you ever try a perpetual, treat the first trades as lessons, not as income, use very low leverage, and risk only money you can afford to lose completely. This guide explains how perpetuals work, it does not recommend using them.

What are the main risks in one place?

The first risk is leverage itself, because it turns ordinary price swings into account-ending moves. The second risk is liquidation, which closes your position automatically and cannot be undone. The third risk is funding cost, which quietly drains your margin when a trade is crowded. The fourth risk is platform risk, because a hack, an outage, or a failure on the platform can cost you money no matter how good your trade was.

A simple safety checklist covers most of it: Know your liquidation price before you open any position, keep leverage low, check the funding rate, and never risk money you cannot afford to lose. Be extra careful with any person or platform that promises guaranteed profits from perpetuals, because guaranteed profit in a leveraged market is a classic sign of a scam.
