Coin-margined futures trading is a powerful tool for crypto investors looking to leverage their positions and gain deeper exposure to digital assets like Bitcoin (BTC) and Ethereum (ETH). This guide will walk you through the essentials of coin-margined futures, how they work on Bitget, key parameters, risk management, and practical trading strategies — all while keeping your understanding clear and actionable.
Whether you're hedging existing holdings or speculating on price movements, this comprehensive overview ensures you're equipped with the knowledge to trade confidently.
What Are Coin-Margined Futures?
Coin-margined futures are derivative contracts where the underlying cryptocurrency (e.g., BTC, ETH) serves as the margin, settlement currency, and unit of account. Unlike USDT-margined contracts, profits and losses are denominated in the base asset itself.
Key Features:
- Pricing Unit: USD
- Common Pairs: BTCUSD, ETHUSD (settled in BTC)
- Settlement: Profits/losses paid in the collateral coin (e.g., BTC)
- Contract Types: Perpetual or delivery (fixed maturity)

Perpetual vs. Delivery Contracts
Understanding the two main types of coin-margined contracts is crucial for choosing the right strategy.
Coin-Margined Perpetual Contracts
- No Expiry Date: Can be held indefinitely
- Funding Rate Mechanism: Periodic payments between longs and shorts every 8 hours
- Best For: Long-term speculation, arbitrage opportunities
Coin-Margined Delivery Contracts
- Fixed Maturity Date: Automatically settles at expiration (e.g., BTCUSD-20250628)
- Settlement Method: Based on spot index price at expiry
- Best For: Hedging, institutional risk management
Example: Suppose you hold a BTCUSD contract expiring on June 27, 2025. At 16:00 UTC+8, the system will settle all open positions at the final index price — say $70,000. A trader holding five BTC futures will either buy or sell five BTC at that rate. Alternatively, traders can close their position before expiry to realize gains or losses earlier.
Advantages of Coin-Margined Futures
- Double Exposure to Asset Growth
If BTC rises, your profits are paid in BTC — meaning you benefit both from increased holdings and rising prices. - Effective Spot Hedging
Hold BTC but fear a short-term dip? Open a short position in BTCUSD to offset potential losses in your portfolio. - Lower Funding Rates
Compared to USDT-based perpetuals, coin-margined contracts often feature more favorable funding conditions due to lower demand imbalances.
Potential Drawbacks
- Complex Profit Calculation
Since P&L is calculated in BTC (not USD), understanding real returns requires converting values based on current market rates. - Higher Liquidation Risk
During sharp price drops, the value of your BTC-denominated margin declines rapidly — increasing the chance of liquidation even if dollar value seems stable.
Core Trading Parameters on Bitget
To trade effectively, familiarize yourself with these essential settings:
- Leverage: Adjustable (e.g., 10x, 50x, up to 100x) — higher leverage increases both profit potential and risk
- Margin Mode: Choose between isolated (per-position margin) or cross (shared account margin)
- Taker Fee: Typically 0.028%–0.042%, charged when you remove liquidity (market orders)
- Maker Fee: Usually 0.0072%–0.014%, applies when you add liquidity (limit orders)
- Funding Rate: Applied every 8 hours for perpetuals; no funding in delivery contracts
- Index Price: Derived from a weighted average of major exchange spot prices — used for fair valuation and liquidation triggers
Order Types & Execution Models
Flexibility in order execution helps refine your trading approach.
Available Order Types:
- Limit Order: Set a specific entry or exit price (e.g., open long at $60,000)
- Market Order: Instant execution at best available price
Execution Instructions:
- GTC (Good Till Cancel): Stays active until filled or manually canceled
- IOC (Immediate or Cancel): Executes immediately what it can; cancels remainder
- FOK (Fill or Kill): Entire order must execute instantly — otherwise, rejected
These models allow precision in volatile markets and help avoid partial fills that could distort your strategy.
How Funding Fees Work
Funding fees ensure perpetual contracts stay anchored to the underlying spot price. They are exchanged between long and short traders every 8 hours.
Formula:
Funding Fee = Position Value × Funding RateThe rate consists of two components:
- Interest Rate (I): Theoretical cost of holding crypto vs. fiat
- Premium Index (P): Reflects the gap between contract price and spot index
Bitget calculates a minute-by-minute premium index and averages it over each 8-hour cycle. The final funding rate adjusts within predefined bounds (a, b) to prevent extremes.
If the difference between interest and premium falls within acceptable limits, the funding rate equals the interest rate — promoting market stability.
Fees are automatically deducted or credited to your wallet at scheduled intervals.

Index Price & Mark Price Explained
Index Price
Represents the true market value of the underlying asset, calculated using data from top exchanges like Binance, Coinbase, and Kraken. Prevents manipulation by averaging multiple sources.
Mark Price
Used to calculate unrealized P&L and determine liquidation triggers. Helps avoid unfair liquidations caused by temporary price spikes.
Mark Price Formula:
Mark Price = Index Price + N-minute Moving Average of [(Bid + Ask)/2 − Index Price]This smoothing mechanism protects traders during flash crashes or illiquid moments.
Note: A small unrealized P&L may appear immediately after trade execution due to minor differences between entry price and mark price. This does not reflect actual profit or loss.
Risk Management & Liquidation Process
Bitget employs robust systems to protect traders and maintain market integrity.
Key Metrics:
- Maintenance Margin Ratio (MMR): Minimum required margin to keep a position open
- Margin Ratio Monitoring: Alerts sent when levels approach liquidation thresholds
Liquidation Trigger:
When MMR reaches or exceeds 100%, the system initiates forced liquidation at the best available market price.
Additional safeguards include:
- Auto-Deleveraging (ADL): In extreme cases, opposing positions may be reduced systematically
- Insurance Fund: Covers residual losses after liquidation to prevent auto-deleveraging where possible
Pro Tip: Always monitor your margin level, use stop-loss orders, and avoid maximum leverage unless highly experienced.
Frequently Asked Questions (FAQ)
Q: What’s the difference between coin-margined and U-margined futures?
A: Coin-margined contracts use crypto (like BTC) for margin and settlement — profits grow with the asset’s value. U-margined (e.g., USDT) contracts offer USD-denominated clarity, making P&L easier to track.
Q: How can I avoid liquidation?
A: Maintain healthy margin levels, reduce leverage, set stop-losses, and choose cross-margin mode for added buffer during volatility.
Q: Do funding fees impact my position?
A: Yes — every 8 hours, perpetual contract holders pay or receive funding based on market sentiment. It’s deducted directly from your balance.
Q: What happens when a delivery contract expires?
A: All open positions are automatically settled at the final index price. Settlement is made in the underlying cryptocurrency (e.g., BTC).
Q: Is mark price the same as my entry price?
A: Not necessarily. Mark price is used for risk calculations and may differ slightly from your fill price — especially during high volatility.
Q: Can I close my position before expiry?
A: Absolutely. Most traders close positions early to lock in profits or cut losses before settlement.
Final Thoughts
Coin-margined futures offer experienced and novice traders alike a strategic way to amplify returns, hedge portfolios, and participate in crypto markets with greater flexibility. However, with higher leverage comes increased responsibility — understanding margin modes, funding mechanics, and liquidation risks is essential.
Whether you're aiming to capitalize on Bitcoin’s long-term growth or protect your holdings during uncertain times, mastering coin-margined contracts gives you an edge in today’s dynamic digital asset landscape.
