What Are Coin-Margined Futures?
Hey there! In the previous article we covered USDT-margined futures. Today let's talk about their sibling -- coin-margined futures.
Coin-margined futures, also called inverse contracts or coin-margined perpetual contracts, have one key distinction: you use the cryptocurrency itself as collateral, and profits and losses are also settled in that cryptocurrency.
For example, to trade the BTCUSD coin-margined contract, you use BTC as margin. Win, and you earn BTC. Lose, and you lose BTC.
Sounds a bit circular, right? Bear with me -- by the end of this article, you'll see why it's clever.
Coin-Margined vs. USDT-Margined: Key Differences
Here's a clear comparison:
| Feature | USDT-Margined | Coin-Margined |
|---|---|---|
| Collateral | USDT/USDC | Corresponding crypto (BTC, ETH, etc.) |
| Settlement currency | USDT/USDC | Corresponding crypto |
| Contract type | Linear | Inverse |
| P&L calculation | Simple and intuitive | Slightly complex (non-linear) |
| Best for | Most traders | Long-term holders, miners |
| Expiry types | Mostly perpetual | Perpetual + quarterly delivery |
The critical difference is the margin and settlement currency. USDT-margined uses stablecoins -- straightforward. Coin-margined uses the crypto itself, which creates an interesting phenomenon: double gains (or double losses).
The "Double Effect" of Coin-Margined Futures
This is the most interesting and important characteristic. Let me illustrate with examples.
Scenario 1: Long + Price Rises (Double Gains)
Suppose you use 1 BTC as margin and go long on BTCUSD. BTC rises from 60,000 to 66,000 (up 10%).
Your futures position profits, earning you more BTC. Meanwhile, the BTC you hold has also appreciated in value.
Contract wins + coin appreciates = double gains
Specifically, at 1x leverage, you'd earn roughly 0.1 BTC. But that 0.1 BTC is now worth $6,600 (not $6,000), because BTC itself also went up.
Scenario 2: Long + Price Drops (Double Losses)
Conversely, if BTC drops from 60,000 to 54,000 (down 10%).
Your futures position loses BTC. Meanwhile, the remaining BTC in your account has also depreciated.
Contract loses + coin depreciates = double losses
This is why coin-margined futures have different risk characteristics than USDT-margined ones -- gains and losses are non-linear. You earn more when things go up, but lose more when things go down.
Scenario 3: Short + Price Drops
If you go short on coin-margined (expecting a price drop) and BTC does fall, your contract earns you more BTC. But BTC itself has depreciated. One gains, one loses -- they partially offset each other.
This characteristic gives coin-margined shorts a natural "hedging" effect. You accumulate more coins even as the price drops, so when the bull market returns, you're holding a larger quantity.
When Should You Choose Coin-Margined?
Understanding the mechanics, let's explore when coin-margined beats USDT-margined.
Situation 1: You're a Long-Term Holder
If you believe in BTC or ETH for the long haul and plan to hold regardless, going long with coin-margined futures adds a leverage layer on top of your long-term position. During bull markets, the double effect makes your returns significantly more impressive.
Situation 2: You're a Miner
Miners continuously produce BTC but need to hedge price risk. Shorting via coin-margined futures locks in some profit. If BTC drops, the contract earns BTC as compensation. If BTC rises, the contract loses BTC, but your holdings are worth more.
Situation 3: You Don't Want to Hold Stablecoins
Some people don't fully trust stablecoins (even though USDT has been fine so far), or they feel converting to stablecoins means missing out on price appreciation. Coin-margined is the better fit here.
Situation 4: Quarterly Delivery Contract Arbitrage
Coin-margined contracts include quarterly delivery contracts, which open up arbitrage opportunities between the delivery and perpetual contract price spreads.
How to Trade Coin-Margined Futures
If you're already familiar with USDT-margined futures, coin-margined is essentially the same process. Here's how on Binance:
Step 1: Prepare Your Margin
Unlike USDT-margined, you need to transfer the corresponding cryptocurrency to your coin-margined futures account. For BTCUSD contracts, transfer BTC.
- Go to the "Coin-Margined Futures" trading page
- Click "Transfer"
- Move BTC from your spot account to the coin-margined futures account
Step 2: Choose Contract Type
Coin-margined offers two options:
- Perpetual: No expiry date, similar to USDT-margined perpetuals
- Delivery: Has an expiry date (typically end of quarter), auto-settles at expiry
Beginners should start with perpetual contracts.
Step 3: Configure and Place Your Order
Leverage settings, margin mode selection, and order types work identically to USDT-margined. The only difference is that your margin and P&L are denominated in BTC or the relevant crypto.
Step 4: Understand Contract Face Value
Coin-margined contracts have a unique aspect: they're denominated in USD face value. BTC contracts have a face value of $100 per contract; ETH contracts have $10 per contract.
So when placing an order, you enter the number of contracts, not BTC quantity. For example, buying 10 BTCUSD contracts means $1,000 in position value. How much BTC is needed as margin depends on the current BTC price and your chosen leverage.
This differs from USDT-margined and takes some getting used to.
P&L Calculation Explained
Coin-margined P&L math is slightly more complex:
Long P&L (in BTC) = Face Value x Contracts x (1/Entry Price - 1/Exit Price)
Short P&L (in BTC) = Face Value x Contracts x (1/Exit Price - 1/Entry Price)
Yes, the formula uses the reciprocal of prices. This is why coin-margined P&L is non-linear: as price rises by the same amount, you earn progressively less BTC; as price falls by the same amount, you lose progressively more BTC.
Here's a concrete example:
You go long on 10 BTCUSD contracts ($100 face value each) at an entry price of 60,000.
- BTC rises to 66,000: Profit = 100 x 10 x (1/60,000 - 1/66,000) = 0.001515 BTC (roughly $100)
- BTC drops to 54,000: Loss = 100 x 10 x (1/60,000 - 1/54,000) = -0.001852 BTC (roughly $100)
Notice: despite an equal 10% move in each direction, you profit 0.001515 BTC but lose 0.001852 BTC. That's the non-linearity in action.
Don't let this intimidate you though. For short-term trades with a few percentage points of movement, the difference is negligible.
Coin-Margined Fees
Fee rates for coin-margined futures are comparable to USDT-margined:
- Maker: 0.01%
- Taker: 0.05%
Since fees are paid in crypto, the actual USD-equivalent cost varies with the coin's price.
Users registered through our exclusive referral link enjoy fee discounts that add up significantly over time.
Special Risk Warnings for Coin-Margined
1. Margin Value Fluctuates
This is the biggest thing to watch. Your margin itself is volatile. If you use 1 BTC (worth $60,000) as margin for a long position and BTC drops, your margin value shrinks too -- liquidation arrives faster than you'd expect.
2. Liquidation Price Calculation Is More Complex
Since margin value changes, liquidation price calculations are more involved than with USDT-margined. Always use Binance's futures calculator to determine your exact liquidation price.
3. Not Ideal for Frequent Altcoin Trading
Coin-margined futures primarily support major coins like BTC and ETH. If you want to trade various altcoin futures, USDT-margined offers a much wider selection.
4. Liquidity May Be Lower
For the same trading pair, USDT-margined volume typically far exceeds coin-margined. Lower liquidity means wider bid-ask spreads and larger slippage on big orders.
Real-World Use Cases
Case 1: Bull Market Accelerator
You own 5 BTC and are firmly bullish. Transfer 2 BTC into coin-margined futures, 3x leverage long. When the bull market arrives, not only do your 5 BTC appreciate, but the contract earns you extra BTC on top. Far better returns than simply holding.
Just remember to set your stop-loss and manage risk.
Case 2: Miner Hedging
You're a miner producing 0.5 BTC per month. Worried about a near-term price drop, you short an equivalent amount via coin-margined futures. If BTC drops, the contract profit offsets your holding losses. If BTC rises, the contract loss is offset by your holdings being worth more.
Case 3: Accumulate Coins + Collect Funding Rate
During bull markets, the funding rate is often positive (longs pay shorts). You can hold BTC in spot while simultaneously shorting an equal amount in coin-margined futures. Spot BTC gains offset contract losses. But you continuously collect the positive funding rate.
This is a low-risk arbitrage strategy that we'll cover in detail in a future article.
Summary and Recommendations
Coin-margined futures aren't for everyone, but they offer unique advantages in specific scenarios:
- Long-term holders: Double gains effect when going long
- Miners: A natural hedging tool
- Arbitrageurs: Great for funding rate arbitrage
- Those who prefer full crypto exposure: Stay fully invested in crypto without holding stablecoins
If you're a pure short-term trader who values simplicity, USDT-margined is probably your better bet. If you're a long-term crypto believer, coin-margined deserves a deeper look.
Regardless of which type you choose, risk management always comes first. Set your stop-losses, manage your position sizes -- these fundamental principles apply equally to both contract types.
