Perpetual contracts for Bitcoin, also known as perpetual swaps, are a highly popular type of futures contract pioneered by exchanges like BitMEX. These instruments allow traders to speculate on Bitcoin's price movements without expiration dates, combining features of traditional futures with innovative funding mechanisms.
Understanding Bitcoin Perpetual Contracts
Core Mechanics
- No Expiration: Unlike standard futures, perpetual contracts don't settle on a fixed date.
- Funding Rate: A periodic payment (every 8 hours) adjusts the contract price toward the spot price.
- Inverse Settlement: Profits/losses are settled in BTC rather than USD.
Key Features
- High leverage (up to 100x on some platforms)
- Cash-settled in Bitcoin
- Synthetic replication of spot market conditions
How Perpetual Swaps Work
The Funding Mechanism
The funding rate ensures price convergence between the contract and Bitcoin's spot price. This happens through:
- Payment Cycles: Every 4:00 UTC, 12:00 UTC, and 20:00 UTC
- Rate Calculation: Based on the difference between contract price and index price
- Directional Incentives: Traders going against the majority position receive funding payments
