What Are Perpetual Futures? A Complete Guide
Perpetual futures — often called 'perps' — are the most traded derivative in crypto markets. Unlike traditional futures, they have no expiration date, allowing you to hold a leveraged position for as long as your margin allows. This guide walks through how they work, the mechanics behind the funding rate, and the tradeoffs versus spot trading.
The core idea: futures without expiry
A traditional futures contract is an agreement to buy or sell an asset at a predetermined price on a specific date. For example, a Brent crude oil June futures contract settles in June at whatever price the market has moved to. When the date arrives, the contract closes and traders either take delivery or settle in cash.
Perpetual futures remove that expiration date. You can hold a long or short position indefinitely, rolling profit and loss continuously. To keep the perp price anchored to the underlying spot price despite having no settlement, the market uses a mechanism called the funding rate — a periodic payment between long and short traders. We cover funding rates in a dedicated guide; for now, think of it as the 'rent' that keeps the contract honest.
This single change — removing expiry — makes perps dramatically more usable for leveraged directional bets. You no longer need to roll contracts every quarter, worry about term-structure pricing, or manage expiration risk. Your only constraint is maintaining enough margin to keep the position open.
How a perp trade works end-to-end
Suppose BTC is trading at $70,000 and you believe it will rise. You deposit $1,000 USDC into your Tenbagger trading account and open a 10x long position, controlling $10,000 of BTC exposure. If BTC rises to $73,500 (a 5% move), your position value grows to $10,500. Subtracting fees, that's roughly a $500 profit — a 50% return on your $1,000 collateral, thanks to 10x leverage.
The reverse is equally important. If BTC falls 5% to $66,500, your position loses $500 — half your collateral. A 10% drop would liquidate you entirely: your $1,000 of collateral can no longer cover a $1,000 loss, so the platform closes the position automatically to protect the counterparty. This is why leverage is often called a double-edged sword: returns are amplified in both directions.
On Tenbagger, orders flow through the Hyperliquid order book. Your market buy matches against the best available ask prices instantly. Alternatively, a limit order waits in the book until someone crosses it. The position appears in your portfolio immediately with live PnL, funding accruals, and liquidation price.
Perpetuals vs. spot trading
Spot trading means buying or selling the actual asset. If you buy 1 BTC on an exchange, that BTC is yours — you can withdraw it, send it to cold storage, or hold it for years. Gains and losses are exactly what the price moves, minus fees. There is no liquidation; the worst case is that your BTC is worth less when you sell.
Perpetual futures, by contrast, are a synthetic derivative. You never own the underlying asset. You hold a contract whose value tracks the price, settled in USDC. You can go short (profit when the price falls) — something spot trading doesn't directly enable. You can apply leverage without borrowing from a lender. And you can enter and exit large positions with fractional capital.
The tradeoffs: perps carry liquidation risk, funding rate costs, and the psychological weight of leverage. For long-term holders who simply want price exposure, spot trading is almost always better. For active traders expressing short-term views or hedging, perps provide flexibility and capital efficiency that spot cannot match.
Who trades perpetuals, and why
Three user archetypes dominate perpetual volume. Directional speculators take leveraged long or short positions based on their view — the most common use case and the primary driver of funding rate dynamics. Hedgers use shorts to offset spot exposure: a BTC miner sitting on unsold inventory might short 50% of their expected production to lock in a price. Arbitrageurs exploit tiny mispricings between venues, between perp and spot, or within the funding rate itself.
Liquidity providers sit on both sides of the book with limit orders, earning the maker rebate and small edges from the bid-ask spread. Professional market makers handle the bulk of this, but retail users can also act as makers by using post-only limit orders. This helps tighten spreads and provides depth for takers — which benefits everyone.
Common misconceptions
'Higher leverage means higher profit.' Not inherently — leverage amplifies whatever price move occurs, but if the direction is wrong, it also amplifies losses and drags your liquidation price closer. Most experienced traders operate at 2x–5x effective leverage on majors, saving higher leverage for short-duration tactical plays.
'Perps are gambling.' Perps are tools. They enable risk management, price discovery, and capital efficiency. Whether a specific trade is gambling or investment depends on the thesis, sizing, and risk controls, not the instrument itself. Used without a plan, any financial instrument is gambling. Used with discipline, perps are a legitimate component of a trading strategy.
'Funding rates are a fee.' The funding rate is a zero-sum transfer between longs and shorts, not a fee paid to the exchange. When longs pay shorts, your short position earns funding while open. When shorts pay longs, your long earns it. This is fundamentally different from a platform fee and is baked into your realized PnL.
