Perps Explained: The Casino Game That Pretends It’s Investing

Perps (aka perpetual futures) are the #1 way people turn a perfectly normal crypto bag into a sad little liquidation notification. This isn’t “investing”. This is strapping your portfolio to a rocket, aiming at your own face, and yelling “price discovery!”

But perps aren’t evil. They’re just… powerful. If you understand how crypto perps work — leverage, liquidation, funding rates, and why the price stays glued to spot — you can stop donating to the market like it’s a charity.

This guide explains perps like a normal human would explain them to a friend who’s about to press “20x” for the first time.

What are perps (perpetual futures), in one sentence

Translation: you can bet up or down, borrow size you don’t have, and you’ll either look like a genius or get force-closed by the exchange in 0.3 seconds.

Perps vs spot: why perps feel like a cheat code

Spot trading is simple:

• You buy ETH.

Perps are extra:

• You open a position (long or short).

If you’re still shaky on basic market mechanics, go read How to Read Crypto Charts first. Then come back and press the spicy buttons.

The “perpetual” part: no expiry, no chill

Normal futures have an expiration date (like “BTC futures, March contract”). Perps don’t expire. You can keep them open as long as:

• you have enough margin,

That last part matters more than you think.

Long vs short: you can bet both directions

• Long = you profit if price goes up.

This is why perps attract chaos. In spot markets, the average beginner is forced to be optimistic. In perps, you can be optimistic, pessimistic, or just emotionally unstable in both directions on the same day.

Margin, leverage, and why “10x” is not a personality trait

Let’s say you have $1,000.

Spot

You buy $1,000 of SOL. That’s it.

Perps with 10x leverage

You put $1,000 as margin and open a $10,000 position.

If SOL moves +5%, your position is up about +$500 (before fees/funding). That’s a +50% gain on your $1,000 margin.

If SOL moves -5%, you’re down about -$500. Do that twice and you’re doing the “I’m fine” meme while the exchange is already measuring you for a liquidation coffin.

Leverage magnifies:

• profits (cute),

Liquidation: the exchange’s “nope” button

Liquidation is when the platform closes your position because your margin can’t cover the loss.

It’s not a moral judgment. It’s risk management. The exchange is basically saying:

> “We are not letting you owe money. We are deleting your position before it becomes our problem.”

Why liquidation happens faster than you expect

Two reasons:

1. You don’t get liquidated at -100%. Fees, maintenance margin, and the liquidation engine kick in earlier.

2. Price wicks exist. A single ugly candle can slap your liquidation price for one second and you’re gone.

If you’ve never experienced a wick liquidation: congrats, you still have innocence.

The hidden boss fight: “maintenance margin”

Exchanges require you to keep a minimum amount of margin in your position, called maintenance margin.

As your position loses money, your margin ratio worsens. When it crosses the line, liquidation begins.

This is why two traders can both be “down 6%” and only one gets nuked:

• trader A is 3x

Same move, different funeral.

How perps track spot price (and why they don’t drift into fantasy land)

If perps had no expiry, the perp price could float away from spot forever. So exchanges use funding rates to keep perp price close to spot.

Think of funding like a little “gravity tax” that pulls the perp market back toward reality.

Funding rates explained (the part people ignore until it hurts)

Funding is a periodic payment between longs and shorts.

• If the perp price is above spot, funding is usually positive: longs pay shorts.

Why?

• When perps trade above spot, the exchange wants to discourage too many longs.

Funding doesn’t go to the exchange (usually). It’s peer-to-peer between traders.

Funding is the “rent” you pay to hold a position

If you hold a 20x long for days during hype season, you might be paying funding every 8 hours like:

• “It’s fine, it’s just a little fee”

That’s funding. That’s the rent.

(We’ll do a deep dive soon — and yes, it deserves its own article. For now, also read What Is MEV? if you want to understand another invisible tax that shows up when you trade on-chain.)

Mark price vs last price: the exchange is not letting you get wick-trolled (sometimes)

Most perp platforms use a mark price to trigger liquidations, not the last traded price.

• Last price can be manipulated by thin liquidity or a random wick.

The goal: reduce “one-second wick” liquidations.

Reality: it helps, but it’s not a forcefield. Low liquidity moments can still cook you.

Fees: perps are not free, and you pay more when you panic

Perp fees usually include:

• maker/taker trading fees

If you’re opening/closing constantly, taker-fee-ing yourself to death is a very real form of self-harm.

Why people trade perps at all (it’s not always degen behavior)

Perps have legit uses:

1) Hedging

You hold spot ETH but you’re scared of a short-term dump.

• Keep your spot.

If price drops, the short profits and cushions the pain.

2) Short exposure (without borrowing)

Shorting spot is annoying in crypto. Perps make it one click.

3) Capital efficiency

You can deploy less capital for the same exposure.

This is only good if you’re disciplined.

If you’re not disciplined, it’s like giving a toddler a flamethrower because “it’s efficient for lighting candles.”

Cross vs isolated margin: choose your own disaster

Most platforms offer:

Isolated margin

Each position has its own margin. If it gets wrecked, only that margin dies.

Cross margin

All your account balance supports your positions. If one position gets wrecked, it can drag the rest of your balance into the abyss.

If you’re a beginner, isolated margin is usually the “least bad” option because it limits the blast radius.

A simple liquidation example (so it clicks)

You have $1,000.

You open a BTC perp long with 10x leverage.

• Position size: $10,000

You do not get a polite email at -10%.

You get a liquidation engine trying to close you before your margin goes negative.

So when you see:

> “BTC is only down 3% today, why am I wrecked?”

The answer is:

• because you were overleveraged,

Perps on CEX vs perps on DEX: same idea, different risks

You can trade perps on:

Centralized exchanges (CEX)

Pros:

• deep liquidity (usually)

Cons:

• custody risk (they hold your funds)

If you need a refresher, read CEX vs DEX.

Decentralized perp DEXs

Pros:

• self-custody vibes

Cons:

• smart contract risk

Security note: if you’re going on-chain, level up with Crypto Security Masterclass first. Don’t learn by getting drained.

The psychology trap: perps turn boredom into bad decisions

Spot investing is boring.

Perps are never boring.

Perps give you:

• dopamine every minute

This is why perps are basically a video game with real money.

And the final boss is you.

The 9 rules of not getting obliterated trading crypto perps

Not financial advice, just survival advice.

1) Start with 1x–3x, not 20x

If you can’t make money at 2x, you won’t make money at 20x.

You’ll just lose faster with better graphics.

2) Use isolated margin

Cross margin is for people who understand exactly what they’re doing.

Beginners don’t.

3) Know your liquidation price before you click confirm

If you don’t know where you die, you’re not trading. You’re gambling with extra steps.

4) Size positions like a boring adult

Small size is a superpower.

Your goal is to stay in the game long enough to learn.

5) Respect funding

If funding is extremely positive and you’re longing, you’re paying expensive rent.

Sometimes the best trade is… not paying rent.

6) Don’t hold high leverage through major news

Macro prints, ETF rumors, protocol hacks, exchange drama — volatility spikes.

Wicks get violent.

7) Use limit orders when you can

Market orders in fast markets can fill you at the worst possible price.

On-chain, slippage can also dunk on you. (We’ll cover DEX limit orders soon.)

8) Don’t average down on leverage like it’s a personality

Averaging down can work in spot.

In perps, averaging down can speedrun liquidation.

9) If you’re stressed, close the position

If you can’t sleep because you’re watching the chart like it owes you money… it’s too big.

“So should I trade perps?”

If your goal is:

• long-term investing → spot + patience is the meta

If your goal is:

• “I want to turn $200 into $20k today” → perps will happily turn $200 into $0 today

And if you’re still building fundamentals, start with:

• What Is DeFi? (so you know what you’re even interacting with)

Perps glossary (quick and painless)

• Perps / Perpetual futures: Futures contracts without expiry.

Bottom line

Perps are a tool. A very sharp tool.

Used right, perpetual futures help you hedge, express directional views, and manage risk.

Used wrong, they turn your portfolio into a live demo of “why risk management exists.”
