Spot means you own the coins; a dated future has a deadline; a perpetual has no deadline, a funding meter and a liquidation price. Nearly every signal you will ever receive trades the third one.

What are you actually buying in each case?

Three instruments carry the same price chart and completely different obligations. Spot means you exchanged money for the asset and own it. A dated future is a contract to settle at a fixed date. A perpetual is a contract with no date at all, kept near the real price by a funding fee, and closed by force if your margin runs out. Everything else in this guide unpacks that table:

Spot Dated future Perpetual
You own the coins Yes, withdrawable No, a contract No, a contract
Expires Never Fixed date Never
Leverage None (without borrowing) Yes Yes, routinely 10-100x+
Ongoing cost None Roll to next contract Funding every 8h
Can be liquidated No Yes Yes
Short possible No Yes Yes

Why this matters here: signal channels almost never trade spot. When a Telegram message says "BTCUSDT LONG 20x", it is quoting the third column, with every obligation that column carries.

What does "spot" mean?

A spot trade is an immediate exchange: your money for the asset, at the current market price. The coins land in your balance, you can withdraw them to a wallet you control, and your maximum loss is what you paid. The position cannot be liquidated, because there is no debt in it.

Spot is the only one of the three instruments where "buy and forget" is a coherent strategy. There is no expiry and no funding meter; nothing needs maintaining. The price can fall, but nobody can close your position for you.

The limitation is the mirror of the safety: no leverage without borrowing, and no way to profit from a fall. Those two gaps are exactly what the other two instruments exist to fill.

What is a dated future?

A traditional future is an agreement to buy or sell at a set price on a set date. CME's bitcoin futures, the institutional standard, expire on the last Friday of the contract month and settle in cash against a reference rate, so no bitcoin changes hands at all.

The expiry date does useful work: as it approaches, the contract's price is pulled toward the real market price, because settlement is coming. The cost of that discipline is maintenance. Keeping exposure past expiry means closing the old contract and opening the next month's, or "rolling", every single month.

Retail crypto traders rarely touch dated futures; they are an institutional habitat. But they are worth understanding for one reason: the word "perpetual" only means something as a contrast to them.

What makes a perpetual "perpetual"?

A perpetual is a futures contract with the expiry date deleted. The position stays open until you close it, or until liquidation closes it for you. The idea is older than crypto: economist Robert Shiller proposed perpetual futures academically, and BitMEX built the modern crypto version in mid-2016 with its XBTUSD contract.

Removing the expiry removes the mechanism that kept a future's price honest. Nothing forces a perpetual toward the real market price at settlement, because settlement never comes. As Deribit's education desk puts it:

"Perpetual swaps do not have an expiry date, therefore they need another mechanism to keep the price of the contract as close to the index price as possible." — Cryptarbitrage, Deribit Insights: Perpetual Swap Funding

That mechanism is the funding rate: the defining moving part of the instrument, and the first recurring cost most beginners meet without knowing they signed up for it.

Who pays whom the funding rate?

Funding is a periodic payment between traders, not a fee to the exchange. When the perpetual trades above the real index price, longs pay shorts, which nudges traders toward selling until the gap closes. When the perpetual trades below the index, shorts pay longs. The exchange transfers the money and takes no cut.

On most venues funding settles every 8 hours; only positions open at the settlement moment pay or receive. The per-interval rate looks tiny (in 2024, BitMEX's XBTUSD funding averaged about 0.017% per interval), and the small number hides the two facts that matter.

First, funding is charged on the full position size, not on your collateral. At 20x leverage, a 0.017% charge on the position is a 0.34% hit to your margin, three times a day if you hold through settlements. Second, funding is usually positive (longs usually pay), so a crowded long trade quietly bleeds while it waits for its target. Multi-day "swing" signals never include this line in their arithmetic.

What do leverage and margin really mean?

Margin is your stake; leverage is the multiplier. A $100 position at 10x requires $10 of margin, and that margin requirement defines how little adverse movement the exchange will tolerate before your stake stops covering the position.

Two account settings decide the blast radius, and signal channels never mention either of them:

  • Isolated margin: only the stake assigned to this position is at risk. Liquidation burns that stake and stops.
  • Cross margin: your whole account balance backs every open position. One losing trade drains margin from everything else, and liquidation triggers at account level, so a single bad position can zero the account.

Defaults differ by exchange, and following a "20x" signal in cross mode with an existing balance is a different trade from the same signal isolated. Check the setting before the first order, not after the first loss.

Where is your liquidation price?

Closer than the leverage number suggests. The naive expectation says 10x leverage survives a 10% move against you. The real formula subtracts the exchange's maintenance margin (the minimum equity that must remain), so liquidation for a 10x long sits around 9% below entry, not 10%. At 50x the distance is under 2%; at 100x, under 1%.

Three details move it closer still. Fees and funding are deducted from margin over time, quietly shrinking the buffer. Liquidation is checked against the mark price — an index-anchored fair price, not the last traded price, so a brief exchange-wide wick can liquidate a position even if the chart "came back" seconds later. And once liquidated, the position is gone; the recovery you watch afterwards happens without you.

Kraken's education pages state the general rule plainly:

"Liquidation occurs when the market moves against a trader's derivatives contract and funds fall below a platform's maintenance margin requirement." — Kraken Learn: What are perpetual futures contracts?

How big do liquidation cascades get?

Liquidations feed on each other: forced closes push the price, which pushes more positions past their maintenance margin, which forces more closes. On October 10-11, 2025, that loop produced the largest deleveraging event on record: about $19 billion of leveraged positions liquidated within 24 hours. Total open interest across major exchanges, meaning the combined value of all open perpetual positions, fell 43% in a day, from $217 billion to $123 billion.

More than 1.6 million traders were liquidated in that event, most of them inside a few hours. One honest nuance: "$19 billion liquidated" is notional position size, not realised losses, so the industry's headline number overstates the money destroyed. The part that is not overstated: every liquidated trader lost 100% of the margin behind the position. For the individual, liquidation is always total.

That event was exceptional in size, not in kind. This is the instrument working as designed under crowding, with no black swan required.

Why do signal channels live in perpetuals?

Because everything about the format wants them there. Perpetuals are where the volume is: on CryptoQuant's 2025 totals, about three-quarters of all crypto exchange turnover runs through futures rather than spot. Every altcoin a channel wants to call has a liquid perpetual quoted in USDT (with USDT posted as collateral); no expiry means a signal stays "valid" indefinitely; and shorts are as easy as longs, which spot cannot offer.

Above all, leverage is what makes a signal's numbers look like marketing. A typical target is a 2-3% move — invisible at 1x, "+40-60%" at 20x. Our own corpus shows the fingerprint (as of August 2026): 92% of the 3,175 signals we parsed state a leverage figure, up to 200x, and 56% are shorts. Neither number is possible on spot. The signal industry is not a spot industry with leverage added; it is a perpetuals industry that quotes coin names.

What that means for you as a follower: every risk in this article — funding drag, margin modes, liquidation distance, cascades — is silently included in every signal you receive. Following crypto trading signals: how it actually works covers the execution side in detail.

What should you check before trading any of these?

For spot, one question decides your safety: custody, meaning where the coins live and who holds the keys. For any leveraged contract, four settings decide your outcome more than the direction of the trade does. All four are chosen before you place an order:

  1. Margin mode — isolated or cross, before the first order.
  2. Liquidation price — computed for your actual size and leverage, not assumed from "1/leverage".
  3. Funding schedule — whether your holding period crosses settlements, and at what rate.
  4. Position size derived from your stop — risk a fixed small share of the account per trade, whatever multiplier anyone advertises.

And if the trade idea came from a signal channel: verify the channel before trusting it with leverage attached. Our index replays every parsed signal against 1-minute exchange candles (the method is on the Methodology page), and How to verify a crypto signal channel before you pay shows the checks anyone can run in minutes. An instrument this leveraged deserves at least that much due diligence about who is telling you to trade it.
