Spot vs Futures

Spot and futures are two distinct ways to gain exposure to the same asset. Spot is direct ownership: settlement happens (near) immediately, you can custody and withdraw the asset, and your maximum loss is your outlay. Futures and perpetuals are derivatives: you post margin to control a larger notional, you do not own the underlying, and you face funding costs and a liquidation price set by your leverage. The two markets are linked through basis and arbitrage, but their risk profiles differ sharply — spot cannot be liquidated, whereas a leveraged future can be force-closed by ordinary volatility.

In plain English — Spot trading means buying or selling the real asset for immediate settlement — you own the coins and can withdraw them. Futures (including perpetuals) are contracts that track the price, usually traded with leverage, where you do not own the underlying. Spot losses are limited to what you put in and you can hold indefinitely; futures add leverage, funding, and liquidation risk that can close you out long before your view plays out.

Spot: you buy 0.1 BTC for $6,000 and hold the actual coins; a 50% drop leaves you down $3,000 but still holding. Futures: a 5x long with the same $6,000 controls $30,000 of exposure — a ~20% adverse move can liquidate the whole margin.
