Every exchange puts spot and futures side by side in the same interface, one tab apart, with the same chart and a very similar-looking order ticket. They are not variations of the same activity. One is buying something; the other is entering a contract about its price, with borrowed size and an automatic exit you do not control.
This guide explains what each one actually does, how a liquidation price is arrived at, what the order types mean in practice, and how to decide which side of the tab you should be on.
Spot: you own the coin
A spot trade exchanges one asset for another at the current price. Buy 0.1 BTC with USDT and 0.1 BTC is credited to your account. You can hold it indefinitely, send it to a wallet, stake it if the exchange offers that, or sell it back. There is no borrowing, no expiry, and nothing that closes the position for you.
The risk is therefore entirely the asset. If it falls 40%, your balance falls 40% and recovers if the price does. Nobody calls in a loan and no clock runs out. This is why long-term positions belong in spot: it is the only version where sitting still is a viable strategy.
The cost is one trading fee on the way in and one on the way out — around 0.10% at standard tier on most exchanges, and 0% on spot at MEXC. That is the whole cost structure.
Futures: you own a position, not the asset
A perpetual futures contract is an agreement whose value tracks the price of an asset you never receive. You post margin — your own money — and the exchange lets you control a position several times larger. Bybit advertises up to 100x, Gate.io up to 150x and MEXC up to 200x on their futures products, which sounds like opportunity and is more usefully read as a warning label.
Two things follow immediately. The fee is charged on the position, not on your margin: $1,000 at ten times leverage opens $10,000 of exposure, and a 0.05% taker fee on that is $5 to enter and $5 to leave. And the profit and loss are calculated on the same $10,000, which is the entire point and the entire danger.
Perpetuals also never settle. A traditional futures contract has an expiry date; a perpetual replaces that with the funding payment described further down, which is what keeps its price tethered to spot.
Leverage is not extra money, it is a larger position
The most useful way to think about leverage is to ignore the multiplier and look only at the position size. Ten times leverage on $1,000 is not "ten times the profit" — it is a $10,000 position, and a 1% move in the market is $100, or 10% of everything you put up.
Run it the other way and the arithmetic gets uncomfortable fast. At 10x, a 10% adverse move is your entire margin. At 50x it takes 2%. At 100x, 1% — and 1% moves happen on a quiet afternoon in crypto. The multiplier does not create an edge; it compresses the distance between you and being wrong.
Experienced traders use leverage to size a position rather than to enlarge one: deciding the exposure they want, then choosing the margin and multiplier that produce it with room to survive noise. That is the opposite of the usual beginner sequence, which starts with the multiplier.
Liquidation: the price where the decision is taken from you
Your margin is collateral. When the loss on the position approaches it, the exchange closes the position to protect the money it lent — that is a liquidation, and it happens automatically, at whatever price the market is at, whether or not you are watching.
The rough version of the arithmetic is worth memorising: at leverage L, an adverse move of about 1/L wipes the margin. Ten times leverage means roughly 10%, twenty times about 5%, a hundred times about 1%. The real trigger comes slightly earlier, because exchanges require a maintenance margin — a small percentage of the position that must remain — and because entry and exit fees come out of the same pot.
Every futures ticket shows an estimated liquidation price before you confirm. Reading it is the single highest-value habit in derivatives trading: if the number sits inside the range the asset moves in on an ordinary day, the position is not a trade, it is a coin toss with a fee attached.
Adding margin to an open position moves the liquidation price further away, and reducing size does the same. Both are cheaper than being liquidated, which crystallises the loss at the worst available price.
Isolated and cross margin decide how much is at stake
Isolated margin ring-fences the position: only the margin assigned to it can be lost. Liquidation ends that trade and leaves the rest of the account untouched. It makes the worst case knowable in advance, which is why it is the sane default while learning.
Cross margin pools the whole futures balance as collateral for every open position. Liquidation comes much later, because everything you have is defending the trade — and when it does come, everything you have is what it takes. Cross has legitimate uses, mostly hedged books where one position offsets another. As a way of avoiding liquidation on a single directional bet, it converts a survivable loss into a total one.
The setting sits next to the leverage selector on every exchange, it can usually only be changed with no position open, and most platforms ship with cross enabled.
Order types, and when each one is the wrong choice
A market order executes immediately at the best available prices. It guarantees the fill and nothing else — on a thin book it walks up several price levels, and it always pays the taker fee. Use it when getting out matters more than the price you get out at.
A limit order names your price and waits. It guarantees the price and not the fill, and it earns the cheaper maker fee when it rests on the book. Most orders should be limit orders; the ones that should not are the ones you place because something is going wrong.
A stop-limit is two prices: a trigger that activates the order and a limit that constrains where it may fill. It is the standard stop-loss tool and it has one famous failure mode — in a fast drop the market blows through both prices and the limit order never fills, leaving the position open and losing. Setting the limit meaningfully below the trigger, or using a stop-market instead, trades a worse fill for a guaranteed exit.
A stop-market triggers into a market order: it will fill, at whatever the price is by then. Take-profit is the same construction pointed the other way. And most exchanges let you attach both to a position at once — a TP/SL pair, sometimes labelled OCO, where the first to trigger cancels the other.
Two flags are worth knowing. Post-only rejects the order rather than letting it cross the spread, which guarantees the maker fee. Reduce-only stops an order from accidentally opening a position in the opposite direction, and belongs on every exit order you place.
Funding: the cost of holding a position that never expires
Because a perpetual has no expiry to force its price back to spot, exchanges use a payment between traders instead. Every eight hours, if the contract trades above spot, longs pay shorts; if it trades below, shorts pay longs. The rate is published in advance next to the contract.
The exchange is not collecting this — it moves between the two sides of the market. What it means practically is that the crowded side of a trade pays for the privilege, and in a strong rally that is the long side, continuously. Held for a week, funding can cost more than the trading fees on the position several times over.
It also means a futures position is never neutral while it waits. Spot exposure sits still for free; leveraged exposure meters.
Which one you should actually be using
If the plan is to accumulate an asset and hold it, the answer is spot, and futures adds nothing but ways to be closed out during a drawdown you would otherwise have sat through. If the plan is short-term directional exposure, hedging a spot holding, or shorting at all, futures is the instrument that does it — spot cannot short and cannot hedge.
For anyone new to it, the sequence that works is unglamorous: trade spot until limit orders and position sizing are automatic, then open futures at low leverage on a size you would be willing to lose entirely, with isolated margin and a stop attached from the first order. Most exchanges offer a demo or paper futures account, and an afternoon there costs nothing and teaches the liquidation mechanic properly.
Whichever you start with, the fee structure is worth setting up once. Accounts opened through a referral link carry the 20% trading-fee discount on Bybit, OKX, Bitget and Gate.io, and MEXC charges 0% on spot — and neither can be applied to an account that already exists, which makes the first click the only one where it is available.
