Understanding Crypto Perps and How They Change Trading

Perpetual futures, commonly called perps, are a specific type of derivative contract that allows traders to bet on the price of a digital asset without ever owning the coin itself. First introduced by the BitMEX exchange in 2015, these contracts do not have an expiration date. This means you can hold a position open for as long as you have enough collateral to keep it running.

The main mechanism that keeps these contracts tied to the actual price of the asset is called a funding rate. Because perps do not expire, they need a way to prevent the price from drifting too far away from the spot market. If the price of a perp gets too high compared to the spot price, traders with long positions pay a fee to those with short positions. This creates a constant tug of war that keeps the market balanced.

For many active traders, perps are attractive because they provide high flexibility and the ability to use leverage. However, this same leverage makes them dangerous for beginners. While they offer a way to profit during both bull and bear markets, they carry a high risk of liquidation if the market moves against your position. As these tools continue to dominate volume across centralized and decentralized exchanges, understanding the funding rate is essential for any serious trader.
