Futures vs Spot: The Core Distinction
Spot means you own the coin; a perpetual is a leveraged contract that just tracks its price. Know the difference.
Look at the two sides above before reading on. Left: you hand over cash and the coin lands in your wallet. It's yours. Right: you post a small deposit and hold a contract that rises and falls with the coin's price, but the coin never touches your wallet. That single difference (own the thing vs. hold a bet on the thing) is the whole module.
Spot: you own the coin
Spot trading is the plain version. You swap cash for an asset at today's price, right now, and you walk away owning it. Buy 1 coin at $100, you paid $100, and 1 coin sits in your wallet. If the price doubles, your coin is worth $200. If it goes to zero, you lost your $100, no more, no less. You can hold it forever, send it to someone, or sell it whenever you like.
"Spot" just means on the spot, immediate delivery at the current price. Simple, and hard to blow up with. That's the baseline everything else is measured against.
A futures contract: an agreement about a price
A futures contract is not the coin. It's an agreement whose value is tied to the coin's price. You don't buy the asset. You take a position that pays out based on where the price goes.
The classic version has an expiry date: "settle this at the end of the month." But the idea underneath is what matters: you're holding a deal that tracks a price, not the asset itself.
Because you never buy the full asset, you only put down a small deposit called margin, a good-faith slice of the position's value. That's what makes leverage possible (next section).
A perpetual: a futures contract with no expiry
A perpetual (or "perp") is the version most crypto traders actually use. It's a futures contract with no expiry date: it just rolls forever. You open it, and it stays open until you close it or you get liquidated.
To keep a no-expiry contract glued to the real spot price, perps use a small periodic payment between the two sides called funding: longs and shorts pay each other a tiny fee every few hours so the contract price doesn't drift away from spot. You don't need the mechanics yet; just know that's the tether.
Why traders use futures
Three real reasons, survival-framed:
- Leverage: control a big position with a small deposit. Post $10 of margin at 10x and you control a $100 position. Your gains and losses are multiplied. This is the thrill and the danger in one sentence.
- Short exposure: you can profit when the price falls, which you can't easily do just holding a coin.
- Hedging: if you own a coin on spot, a short perp can offset a drop, locking in value without selling.
The catch: leverage means you can lose your whole margin fast, and be liquidated, the position force-closed when your margin can't cover the loss. Own-the-coin spot can't liquidate you. A leveraged contract can, and will.
The key differences: settlement + risk
| Spot | Perpetual | |
|---|---|---|
| What you hold | The actual coin | A contract tracking the price |
| Leverage | None (1x) | Yes, often high |
| Can be liquidated? | No | Yes |
| Expiry | Never | Never (rolls) |
| Profit if price falls? | No (must sell first) | Yes (go short) |
| Worst case | Coin goes to $0 | Lose margin + liquidated early |
The mental model: spot is ownership, a perpetual is a leveraged bet with a tether. One survives a bad week untouched. The other can be closed out before the week even ends.
Dated futures vs perpetuals: the difference
A dated (or "quarterly") future settles on a fixed calendar date. On that day, the contract closes at a final settlement price and cash changes hands. You can't hold past expiry. Its price can trade above or below spot (called contango / backwardation), and that gap shrinks to zero as expiry approaches.
A perpetual never expires, so there's no natural pull back to spot. Instead it uses a funding rate, exchanged typically every 8 hours (some venues hourly):
- Funding positive → longs pay shorts (contract trading above spot; discourages longs).
- Funding negative → shorts pay longs (contract trading below spot).
This steady payment nudges the perp price back toward the underlying spot index, replacing the "expiry pull" that dated futures get for free.
How shorting actually works
Going short means you profit when the price falls. The intuition: you're agreeing to sell high now and buy back low later, pocketing the difference.
Worked example (10x short, $10 margin controlling a $100 position):
| Price move | Position result | Your P&L on $10 margin |
|---|---|---|
| −5% | Short gains 5% of $100 = +$5 | +50% |
| +5% | Short loses 5% of $100 = −$5 | −50% |
| +10% | Short loses $10 | −100% → liquidated |
Two things to burn in: gains and losses are on the full position size, not your margin: that's leverage. And a short's loss has no ceiling in theory (price can rise indefinitely), which is why risk controls matter more on shorts.
Execution & settlement differences
Spot settlement: you exchange cash for the asset and the coin is delivered to your wallet/account. Settlement is the transfer of ownership. Done, no ongoing obligations.
Perpetual settlement: there's no delivery of the underlying. The contract is cash-settled continuously against a mark price, a reference price (usually an index of several spot venues) used to value your position and trigger liquidation. Key ongoing mechanics while the position is open:
- Margin is checked live; if equity falls below the maintenance requirement, you're liquidated.
- Funding is debited/credited on schedule regardless of whether you're up or down.
- Closing the position is just opening the opposite trade. There's no coin to hand back.
So spot is a one-and-done ownership transfer; a perpetual is a live, marked-to-market position with running costs until you close it.
Quick knowledge check
When you buy on spot, what do you actually hold? The real asset: the coin itself, sitting in your wallet, yours to keep with no expiry or leverage.
What makes a perpetual different from a dated futures contract? It has no expiry: it rolls forever, using a periodic funding payment (instead of a settlement date) to stay tethered to the spot price.
Why can a perpetual position get liquidated when spot can't? Because it's leveraged on a small margin deposit; once losses eat that margin, the position is force-closed. Owning a coin outright has no margin to run out.
