Perpetual Futures Explained

Perpetual futures are the most-traded crypto derivative, yet the mechanics behind them confuse most beginners. This guide breaks down how perpetuals work, how they differ from dated futures, why funding rates exist, and which one makes sense when you're starting out.

What is a perpetual future?

A perpetual future (often called a "perp") is a derivative contract that lets you bet on the price of an asset like Bitcoin without ever owning it. You can go long or short, and you can use leverage to control a larger position than your deposit.

The defining feature is in the name: a perpetual has no expiry date. A traditional futures contract settles on a fixed calendar date, after which it ceases to exist. A perpetual can be held open indefinitely, as long as you keep enough margin to avoid liquidation.

This creates a problem. Normal futures converge to the spot price automatically as expiry approaches. A contract with no expiry has nothing forcing it back toward the real market price. The solution is the funding rate, covered below.

Perpetual vs dated (traditional) futures

A "dated" future has a settlement date baked in — for example, a contract that settles on the last Friday of the quarter. Here is how the two compare:

Most crypto volume sits in perpetuals because traders never have to think about expiry or rolling positions. Dated futures still matter for institutions hedging to a specific date and for traders capturing the gap between futures and spot (the "basis").

How the funding rate keeps price in line

Because a perpetual never expires, the exchange uses funding payments to keep its price anchored to the spot ("index") price. Funding is a periodic payment exchanged directly between long and short traders — the exchange does not keep it.

• Perp price above spot → funding is positive → longs pay shorts. This makes going long more expensive and discourages the premium, pulling price down toward spot.
• Perp price below spot → funding is negative → shorts pay longs. This pushes price back up toward spot.

Funding is usually settled every 8 hours (three times a day on many venues), though some exchanges use 1-hour or 4-hour intervals. You only pay or receive if you hold a position at the exact funding timestamp. For a deeper breakdown, see what is a funding rate.

Note that funding is charged on position size, not your margin. With 10x leverage, a $1,000 deposit controls a $10,000 position, so funding is calculated on the full $10,000. This is a cost many beginners overlook.

Price convergence: a quick comparison

Both contract types ultimately track spot, but they get there differently.

1. Dated future: If a quarterly contract trades at $62,000 while spot is $60,000, that $2,000 premium must shrink to zero by expiry. As the date nears, the gap mechanically closes — there is no choice, because at settlement the contract is worth exactly the index price.
2. Perpetual future: There is no forced endpoint. Instead, whenever the perp drifts above or below spot, funding makes the more crowded side pay the other, creating a continuous economic incentive that drags price back. It's a tug-of-war, not a deadline.

Which should a beginner choose?

For most newcomers, the honest answer is to start with neither, then prefer perpetuals if you do trade derivatives. Spot trading (actually owning the coin) carries no leverage, no liquidation, and no funding — it is far more forgiving while you learn.

If you move to derivatives, perpetuals are usually the more practical first step because there is no expiry to manage and liquidity is deepest. But they come with real, repeating costs and amplified risk:

• Leverage cuts both ways. 10x leverage means a ~10% move against you can wipe out your margin. Understand liquidation before sizing up.
• Funding is a drag on long-held positions. In a strongly bullish market, longs can pay funding continuously — small amounts that add up.
• Always use a plan. Set a stop-loss and take-profit and apply sensible position sizing before entering.

Choose a dated future only if you have a specific reason to bet on a calendar window or to hedge to a known date, and you understand rollover. There is no setup that wins automatically; both instruments can lose money quickly when leveraged. Treat derivatives as tools with sharp edges, learn the mechanics on small size, and never risk money you cannot afford to lose.
