Perps vs Spot vs Futures: A Beginner's Primer

You have $600 and want $6,000 of Bitcoin exposure. On spot, that is impossible — you simply buy $600 worth and wait. But with a perpetual future, that $600 can control the full $6,000 position. That amplification is the draw. So is the ability to profit when prices fall. Understanding how that works — and what can go wrong — is what this article is about.

This is Part 1 of the Onchain Perps: Hyperliquid, Drift, dYdX in 2026 series. It builds the vocabulary the rest of the series depends on. No prior derivatives experience is required, but a basic familiarity with what DeFi actually is will help.

Spot Trading: What You Already Know

Spot trading is the simplest form of market participation. You exchange one asset for another at the current market price, and you own the thing when the trade settles. If you buy 0.1 BTC on a spot market, you hold 0.1 BTC.

There is no expiry date, no ongoing cost beyond the trade fee, and no embedded leverage. The capital requirement equals 100% of the position size: holding $6,000 of BTC requires $6,000. Your only risk is that the price falls after you buy — and you can only profit from prices going up. Betting against an asset on spot requires borrowing and selling it first, which most retail traders cannot do easily.

Traditional (Dated) Futures: The Predecessor

A dated futures contract is a binding agreement to buy or sell an asset at a fixed price on a specific future date. Both parties must settle at expiry, regardless of whether the price moved in their favor.

Because the contract expires, traders who want continuous exposure must roll — close the expiring contract and open the next one — paying roll costs each time. Contracts also trade at a premium (contango) or discount (backwardation) to the current spot price depending on market conditions, so the contract price can diverge from spot as expiry approaches. CME Bitcoin futures are the canonical example: institutional desks use them for hedging, but forced settlement is operationally inconvenient for active traders. Traditional crypto futures are almost always cash-settled in USDT or USDC rather than physically delivered.

Perpetual Futures: No Expiry, No Roll

A perpetual future — usually called a perp — is a derivative contract that tracks an asset's price, allows leverage, and never expires. A position can stay open indefinitely as long as margin requirements are met. The trader, not a calendar, decides when to close.

BitMEX announced the first crypto perpetual swap on May 13, 2016. It became the most-traded crypto derivatives product of all time, and the design it introduced — no expiry, funding-rate-anchored pricing — is now the standard across every major venue.

With no expiry, there is no roll cost and no forced settlement. But the discipline that expiry provided — pulling contract prices back toward reality — had to be replaced by something else.

The Funding Rate: The Invisible Anchor

The mechanism that keeps a perp price honest is the funding rate: a small recurring payment exchanged directly between the traders who hold long positions and those who hold short positions.

When the perp trades above spot, longs pay shorts (positive rate) — this makes holding a long position slightly more expensive, discouraging buying and nudging the price back down. When the perp trades below spot, shorts pay longs (negative rate) — making the short side more expensive and nudging the price back up. The result is continuous, market-driven pressure that keeps the perp price tethered to the underlying asset's real market price.

Funding is not a fee paid to the exchange — it is a transfer between opposing traders. Its sign and size shift with market sentiment.

Funding rates, their calculation, and how insurance funds manage extreme dislocations are covered in depth in Part 4 of this series. For now, treat funding as a small recurring cost (or rebate) that is the price of having no expiry date.

Long, Short, Leverage, and Margin

Four terms you will encounter constantly:

Long means you profit if the price rises. Short means you profit if the price falls. Perps make both directions equally accessible without requiring you to borrow the underlying asset.

Leverage lets you control a large notional position with a smaller margin deposit. Notional value is the full dollar size of the position you control. Margin is the collateral you actually post. With 10x leverage, a $600 margin deposit controls $6,000 of BTC exposure. With 40x leverage, $150 controls that same $6,000 notional.

There are two margin thresholds to know. Initial margin is the collateral required to open the position. Maintenance margin is the minimum required to keep it open. If losses erode your account balance down to the maintenance floor, the venue can liquidate your position — closing it automatically to prevent your balance from going negative.

Liquidation is covered in depth alongside funding rates in Part 4.

Why Traders Use Perps

Perps combine several advantages that no single instrument previously offered together:

Onchain Perp DEXs vs Centralised Exchange Perps

Until recently, perpetuals were almost exclusively a centralised-exchange product. That has changed materially.

Decentralised perp exchanges captured approximately 19.2% of the global perpetuals market in January 2026 — up from a fraction of that two years earlier. Onchain perp DEX monthly volume grew roughly 8-fold from approximately $81.74 billion in January 2024 to $739.48 billion in January 2026, crossing $1 trillion in a single month in late 2025. Cumulative perp DEX volume reached approximately $6.7 trillion in 2025, a 346% increase from roughly $1.5 trillion in 2024.

The case for onchain perps comes down to self-custody. When you trade on a perp DEX, the smart contract enforces the rules — you never hand control of your collateral to a centralised counterparty. A platform collapse does not put your margin at risk in the way an exchange insolvency can.

The trade-offs are real. Onchain perps can involve slower finality, chain-specific gas fees, and occasionally shallower liquidity than the largest centralised exchanges. Purpose-built venues have closed much of the performance gap, but not all of it.

Hyperliquid is currently the dominant onchain perp venue. Its 30-day volume exceeded $180 billion as of late April 2026, representing roughly 70% of all onchain perpetual DEX volume. Jupiter, dYdX, GMX, and Drift each remained below 3% of DEX market share. The design choices behind these platforms — and what separates them — are the subject of Part 2 of this series, which covers orderbook versus AMM-based perp designs.

The oracles and price feeds that these venues rely on to mark positions are also worth understanding — they are the infrastructure that makes onchain price discovery trustworthy.

Risks to Understand Before You Participate

Leverage cuts both ways. If 10x leverage means gains are amplified tenfold, it equally means losses are amplified tenfold. A 10% move against a 10x leveraged position wipes out the entire margin deposit. At 40x, a 2.5% adverse move achieves the same result.

Liquidation risk is the most direct danger. When your margin balance falls to the maintenance threshold, your position is closed automatically — often at a worse price than you would have chosen — and the loss is realised immediately. There is no waiting for a recovery.

Funding rate risk is subtler. In strongly trending markets, funding rates can become persistently positive or negative, turning a technically correct directional bet into a slow drain. A long position held during an extended bull run may pay significant cumulative funding even as the price moves in your favor.

Liquidation cascades can amplify volatility. When many leveraged positions get liquidated near the same price level, the resulting sell (or buy) pressure can trigger further liquidations, creating sharp, fast moves that are disproportionate to any new fundamental information.

No leverage level is inherently safe. Lower leverage reduces liquidation risk but does not eliminate it. Start with the smallest leverage your strategy requires.
