Difference Between Binance USDⓈ-M and COIN-M Futures: Which One Should HODLers Choose?
USDⓈ-M uses USDT for profit/loss, while COIN-M uses the underlying coin. Their risk structures are vastly different. This guide provides a decision tree for choosing between them.
The choice between USDⓈ-M and COIN-M futures depends entirely on your trading goals. First, activate your futures account on the Binance Official Website and download the Binance Official App (for iOS, see the iOS Installation Guide).
Comparison at a Glance
| Dimension | USDⓈ-M | COIN-M |
|---|---|---|
| Margin Currency | USDT / USDC | Underlying Coin (BTC, ETH, etc.) |
| PnL Settlement | USDT / USDC | Underlying Coin |
| Suitable For | Speculators without holdings | Long-term HODLers |
| Price Risk | One-way USD valuation | Two-way amplification |
USDⓈ-M Futures
This is the most common form of futures. Margin is kept in stablecoins like USDT, and profits/losses are settled in USDT.
Features:
- Intuitive calculation (profit is measured directly in dollars).
- Easy-to-understand USD-based mindset.
- Funding rates are settled in USDT.
- No need to own the underlying asset.
COIN-M Futures
The margin used is the coin corresponding to the contract. For example, a BTC contract uses BTC as margin, and an ETH contract uses ETH.
Features:
- Natural use of funds for HODLers.
- Profits/losses directly increase or decrease the quantity of the coin you hold.
- In an uptrend, you benefit from both the price increase and the trading profit.
- In a downtrend, the margin itself depreciates, compounding the risk.
Why HODLers Prefer COIN-M
Assume you are bullish on BTC long-term and hold 10 BTC in your account.
Using USDⓈ-M to Long BTC
- You must sell some BTC for USDT to use as margin.
- This effectively reduces your position.
- Profits are in USDT, meaning you have to buy back BTC if you want to increase your holdings.
Using COIN-M to Long BTC
- You use your BTC directly as margin without selling.
- Profits are settled directly in BTC.
- You get the "holding + leverage" double gain effect.
Two-Way Risk of COIN-M
The defining characteristic of COIN-M is the "double impact of price and position."
During an Uptrend
- Coin price rises: Your margin currency becomes more valuable.
- Long position profits: You earn even more of the coin.
- Result: Double benefit.
During a Downtrend
- Coin price falls: Your margin currency loses value.
- Long position loses: You lose more of the coin.
- Result: Double blow.
Liquidation for a long position in COIN-M is more severe than in USDⓈ-M because the margin itself is losing value while the position is taking a loss.
Advantages of USDⓈ-M
| Scenario | Advantage |
|---|---|
| No holdings | Only viable choice. |
| Short-term trading | Clear PnL calculation in USDT. |
| Long/Short both | No bias towards any specific coin. |
| Arbitrage | Standardized and easy to hedge. |
Advantages of COIN-M
| Scenario | Advantage |
|---|---|
| Long-term HODLers | Capital is already available in the coin. |
| Bull market longs | Double earnings effect. |
| Hedging | Use COIN-M shorts to hedge against downside price risk. |
| Lower fees | No need to frequently swap for USDT. |
Decision Tree
Start
├─ Do you hold a significant amount of a specific coin?
│ ├─ Yes → Are you bullish on this coin long-term?
│ │ ├─ Yes → COIN-M (HODL + Double Earning)
│ │ └─ No → USDⓈ-M or Sell Spot
│ └─ No → USDⓈ-M
└─ Primarily shorting?
├─ Yes → USDⓈ-M (To avoid margin depreciation pressure)
└─ No → Follow the branch above
Hedging with COIN-M Shorts
Advanced strategy:
You hold 1 BTC (and don't want to sell), but you expect a short-term drop in price.
Operation:
- Open a 1 BTC short in COIN-M BTC futures (1x leverage).
- Keep your 1 BTC spot holding.
Effect:
- Price falls: Your spot loses value, but your short earns more BTC, maintaining your total BTC quantity.
- Price rises: Your spot gains value, but your short loses BTC.
This is roughly "market neutral," where price fluctuations do not significantly change the USD value of your total holdings.
Ideal for: HODLers who are unsure of short-term direction but don't want to reduce their position.
Funding Fees in COIN-M
In COIN-M, funding fees are settled in the underlying coin. If you are long and the rate is positive, BTC will be deducted from your account.
If funding rates are high and you hold a long position for a long time, your BTC quantity will be slowly eroded by these fees.
Liquidity
Generally, liquidity follows this order: USDⓈ-M > COIN-M > Altcoin COIN-M.
COIN-M is mostly active for BTC and ETH. Liquidity for other altcoins in COIN-M can be significantly lower.
Switching Between Them
Each trading pair allows you to choose either USDⓈ-M or COIN-M (they are essentially two separate products).
Before switching, you must manually transfer funds between your USDⓈ-M wallet and your COIN-M wallet.
Common Mistakes
1. HODLers Using Only USDⓈ-M
This misses out on the double earning potential of COIN-M.
2. Non-HODLers Forcing COIN-M
Buying spot just to use it as COIN-M margin forces you into an entry, violating neutrality.
3. High Leverage COIN-M Longs in a Bear Market
As the coin price drops, margin depreciates. High leverage leads to near-instant liquidation.
4. Ignoring COIN-M Funding Fees
HODLers may hold long positions for months, unaware that their BTC count is being slowly eaten away by funding fees.
FAQ
Q: Can I open both USDⓈ-M and COIN-M positions simultaneously? A: Yes, they are managed in two independent accounts.
Q: Can I use BNB to pay fees in COIN-M? A: USDⓈ-M supports it fully. COIN-M has partial support.
Q: Which has lower fees? A: The base rates are the same. VIP levels and BNB discounts apply similarly.
Q: Is there USDC margin in COIN-M? A: No. COIN-M forces the use of the underlying coin.
Q: Can I short ETH in COIN-M using BTC margin? A: No. Each COIN-M pair only accepts its own underlying coin as margin.
Further Reading
USDⓈ-M is the default choice. COIN-M only makes sense when you already hold the coin and want to use it as margin for futures trading.
