Listen, if you've been wanting to understand what perpetual contracts are and how to trade them, this is exactly what you need. I see many people jumping into this topic blindly and then losing money. Let me explain everything to you step by step.

Perpetual contract (perpetual futures, or PERP) — is essentially an agreement between two parties that one will buy, and the other will sell cryptocurrency at a certain price in the future. But here’s the catch: unlike regular futures, perpetual contracts have no expiration date. That’s why they’re called perpetual. For example, BTC-PERP is a contract for Bitcoin.

Now, how does this differ from simply buying crypto on the spot? When you buy Bitcoin on the spot market, you actually hold it, can transfer it, sell it, or use it. But when you trade a contract, you only hold a paper claim that confirms you have the right to that asset, but you don’t physically own it. Settlement happens later, not immediately.

Why do you need these contracts at all? There are several reasons. First, hedging — risk protection. Second, if you believe the price will fall, you can open a short position and profit from the decline, even if you don’t own the asset. And third, there’s leverage. This is a powerful tool that allows you to control a larger position with less capital. For example, with 10x leverage, you can open a $1,000 position with only $100. Of course, this works both ways — profits are amplified 10 times, but so are losses.

Now, the most important part — how does it work in practice? If you open a long (bullish position), you’re betting on the price going up. Bought a contract for $100, and A rises to $120 — that’s a $20 profit. If you open a short (bearish position), you’re betting on a decline. Sold a contract for $100, and the price drops to $80 — again, $20 in your pocket.

Here, it’s crucial to understand margin mechanics. When you open a position, you deposit initial margin — your collateral. Suppose you put in $100 for a position with 10x leverage on $1,000. If the price drops by 10%, your position is now worth $900, a loss of $100, and your margin will be wiped out, leading to forced liquidation.

There’s also maintenance margin. If you see your margin nearing zero but don’t want to be liquidated, you can add more funds to keep the position open. But if you don’t, the system will automatically close your position, and you’ll lose your entire collateral.

One key thing to know is the funding rate. This is a fee exchanged between traders that helps keep the contract price close to the spot price. If most traders are long, the bulls pay shorts. If most are short, shorts pay bulls. The rate is calculated every 8 hours, and you can see it on the trading page or on Coinglass.

There’s also the marked price — the fair value of the contract, which helps prevent incorrect liquidations in volatile markets. When you hold an open position, your profit and loss are unrealized — they fluctuate with the price. When you close the position, everything becomes real.

By the way, about the insurance fund. It’s a mechanism that protects profitable traders if the system can’t close losing positions in time. In short, if you make a profit but your counterparty goes bankrupt, the insurance fund covers the losses.

Now, about the riskiest part — liquidation. It’s not just when your margin runs out. Crypto is volatile, and sometimes the price suddenly drops or spikes briefly, then returns. This is called a pump or dump. It can easily trigger liquidation without giving you time to add margin. That’s why it’s essential to set stop-loss orders.

There are two types of orders — market and limit. Market orders execute immediately at the current price if you’re in a hurry. Limit orders only execute if the price reaches your target level, but may not fill at all if the market doesn’t hit that point.

And finally — contracts based on USDT and contracts based on tokens. USDT-based contracts mean calculations are in US dollars, so you clearly see your profit and loss in USD. Token-based contracts settle in the actual crypto, and if the crypto drops, your paper profit can vanish.

In general, perpetual contracts are a powerful tool but highly risky. Some get rich overnight, others lose everything. The main thing is to understand the mechanics, avoid excessive leverage, and always set stop-losses. Start small, learn through practice, and then you’ll be able to trade wisely.
