When you open Bitunix to place a futures trade, the mechanics behind your margin matter as much as the trading interface. The currency used for margin and settlement affects how you track PnL, manage collateral, and assess your exposure.
That’s why Bitunix introduced USDC-M Futures and increased the maximum leverage available on BTC/USDT and ETH/USDT perpetual futures to 200x. These are separate product changes, but they address the same practical question: how much flexibility do traders have when choosing their futures setup? For perpetual positions, crypto funding rates are another cost to monitor because funding payments can affect the margin balance over time.
What Is USDC-M Futures?
USDC-M Futures are futures contracts that use USDC as the margin and settlement currency.
If you trade a USDC-M contract, you post USDC as margin and your futures PnL is settled in USDC. This gives traders a stablecoin-denominated unit for tracking position performance instead of settling PnL in the underlying cryptocurrency.
For example, if you already hold USDC and want to trade a BTC USDC-M contract, you can use that USDC as futures collateral without first converting it into another margin asset.
This can make portfolio accounting more straightforward, particularly for traders who prefer to measure their futures exposure in a USD-linked unit.
Why Does the Margin Currency Matter?
The margin currency determines what asset you put at risk as collateral and what unit your realized PnL is settled in.
With USDC-M:
The structure is similar to other stablecoin-margined futures products. MEXC, for example, currently describes USDT-M and USDC-M as stablecoin-based futures, while Coin-M contracts use the underlying cryptocurrency for margin and settlement.
USDC-M vs USDT-M Futures
The main difference is the stablecoin used for margin and settlement. Both structures are designed to keep futures PnL in a stablecoin-denominated unit rather than the underlying cryptocurrency.
Feature | USDC-M Futures | USDT-M Futures |
Margin asset | USDC | USDT |
Settlement currency | USDC | USDT |
PnL denomination | USDC | USDT |
Collateral type | USD-pegged stablecoin | USD-pegged stablecoin |
Accounting | USD-linked | USD-linked |
Typical use case | Traders holding or preferring USDC | Traders holding or preferring USDT |
Contract availability | Exchange-specific | Exchange-specific |
Leverage | Depends on contract and risk tier | Depends on contract and risk tier |
The practical difference is often less about trading mechanics and more about which stablecoin you want to hold as collateral.
On Bitunix, USDC-M is integrated into the existing futures environment, so traders can use the same general futures workflow while choosing USDC as their margin currency.
How USDC-M PnL Works
USDC-M futures use a stablecoin-denominated PnL model, which makes the dollar value of gains and losses easier to track.
For a simplified linear futures example, if a trader opens a 1 BTC long position at $60,000 and closes it at $63,000:
PnL = ($63,000 - $60,000) × 1 BTC = +$3,000
The actual realized amount is settled in USDC for a USDC-M contract, before applicable trading fees and funding.
For a short position, the direction reverses:
PnL = ($60,000 - $63,000) × 1 BTC = -$3,000
The exact contract specifications, quantity conventions, fees, and risk calculations can vary by exchange and product, so traders should always check the contract details shown on the trading platform.
USDC-M vs Coin-M: Why the Settlement Asset Changes the Risk Profile
USDC-M is also useful to compare with Coin-M Futures because the two structures create very different collateral exposure.
With Coin-M Futures, the underlying cryptocurrency is used as margin and PnL is settled in that cryptocurrency. Bitunix describes its Coin-M perpetual contracts this way: a BTC-M position uses BTC as margin, and realized PnL is settled in BTC.
That creates an additional layer of price exposure.
For example, if BTC is your Coin-M collateral, a decline in BTC's market value can reduce the USD value of your collateral even before considering the PnL on your futures position.
USDC-M avoids that particular source of collateral volatility because the margin is denominated in USDC.
This doesn't mean USDC-M is automatically safer. Leverage, position size, maintenance margin, market volatility, and liquidation rules still determine the risk of a futures position.
What Is 200x Leverage?
200x leverage means a trader can control a position with a notional value that is up to 200 times the posted margin, subject to the applicable contract and risk limits.
For a simplified example, $100 of margin at 200x could correspond to a $20,000 position.
That doesn't mean the trader can lose only $100 without consequence. A relatively small adverse price movement can consume the available margin quickly when leverage is high.
Leverage changes the relationship between position size and margin. It doesn't reduce the underlying market risk.
Why 200x Leverage Requires More Margin Discipline
At high leverage, small price movements can have a large impact on the margin supporting a position.
For example:
A $20,000 position with $100 margin has 200x nominal leverage.
A $20 move in the underlying represents $20 of PnL on a 1-unit position, before fees and other adjustments.
A larger adverse move can rapidly reduce available margin.
Maintenance-margin requirements and liquidation rules determine when a position can be force-closed.
The actual liquidation threshold isn't simply “1 ÷ leverage.” Exchanges use maintenance-margin rates, position tiers, mark price, fees, and other risk parameters.
For that reason, traders using high leverage should pay close attention to position size and liquidation price, rather than looking at the leverage number alone.
BTC and ETH Perpetual Futures Support Up to 200x
Bitunix announced that the maximum leverage available on BTC/USDT and ETH/USDT perpetual futures was increased from 125x to 200x, subject to position size and applicable risk limits.

The 200x setting is designed for advanced futures users who understand how leverage, margin, liquidation, and position sizing interact.
If you use high leverage, the practical controls matter more than the headline number:
Position size: Keep exposure appropriate for available margin.
Margin mode: Understand the difference between isolated and cross margin before opening a position.
Liquidation price: Know how close the position is to forced liquidation.
Protective orders: Consider stop-loss and take-profit orders where appropriate.
Funding: Include recurring funding costs when estimating the cost of holding a perpetual position.
Does Funding Rate Apply to USDC-M Futures?
Funding is a feature of perpetual futures, not simply a feature of USDT-M or USDC-M.
Perpetual contracts don't have a fixed expiry date, so funding payments help keep the perpetual price aligned with the underlying spot market. When the funding rate is positive, longs generally pay shorts; when it is negative, shorts generally pay longs.
Bitunix's futures interface also provides funding information for USDC-M contracts. The platform's funding documentation calculates funding fees based on position value and the applicable funding rate.
This means leverage isn't the only cost to consider. A trader holding a large perpetual position across multiple funding settlements should also account for potential funding payments.
USDC-M Futures: Who Might Prefer Them?
USDC-M can be a practical fit for traders who already manage capital in USDC or prefer USDC-denominated accounting.
Traders Holding USDC
If your available futures collateral is already in USDC, USDC-M can reduce the need to convert that collateral into another stablecoin before trading.
Traders Who Prefer USDC-Based PnL
USDC settlement keeps realized PnL in the same stablecoin denomination, which can make performance tracking easier.
Traders Using Multiple Stablecoins
Some traders maintain both USDT and USDC for different purposes. Having more than one stablecoin-margined futures option lets them choose the collateral that fits their existing portfolio structure.
The right choice depends on the contract, fees, liquidity, risk limits, and your own collateral preferences rather than the stablecoin name alone.
How to Get Started With USDC-M Futures on Bitunix
If you want to trade USDC-M Futures on Bitunix:
Log in to your Bitunix account.
Deposit or purchase supported assets, then obtain USDC.
If your USDC is held in Spot, transfer it to your Futures wallet.
Open the Bitunix Futures trading page.
Select a USDC-M contract.
Choose your margin mode and leverage.
Review the order details, margin requirements, and liquidation information before placing the trade.
The exact contract list and available leverage can change as Bitunix updates its futures products, so check the trading interface for the current parameters before opening a position.
If You Want to Trade BTC or ETH With Up to 200x Leverage
Open BTC/USDT or ETH/USDT perpetual futures.
Select the leverage setting available for your position.
Confirm the applicable position-size and risk limits.
Review the estimated liquidation price and margin requirements.
Place the order only after checking the full position parameters.
The 200x maximum is a maximum available setting, not a recommended trading level. The amount of leverage appropriate for a position depends on its size, volatility, margin, and risk tolerance.
USDC-M vs USDT-M: Which Should You Choose?
There isn't a universal winner. The more useful question is which collateral structure fits the way you manage your trading capital.
If you... | Consider |
Already hold USDC as trading collateral | USDC-M |
Prefer USDT for futures accounting | USDT-M |
Want PnL denominated in a stablecoin | USDC-M or USDT-M |
Want to keep BTC or another coin as futures collateral | Coin-M |
Want to avoid converting stablecoin collateral before trading | Choose the matching stablecoin-margined contract |
Are comparing leverage | Check the specific contract's current risk limits rather than the margin type alone |
The margin currency is only one part of the decision. Trading fees, funding rates, liquidity, contract availability, leverage limits, and liquidation rules can all affect the final trading setup.
Common Mistakes When Using USDC-M Futures
Treating 200x as a Target
A higher leverage setting doesn't automatically make a strategy more efficient. It increases the amount of market exposure relative to margin and can reduce the room available for adverse price movements.
Ignoring Funding
A position that looks profitable before funding may have a different net result after repeated funding payments.
Confusing Margin With Position Size
Posting $100 of margin doesn't mean the position is worth $100. With leverage, the notional position can be substantially larger.
Assuming USDC-M and USDT-M Are Identical Everywhere
The basic margin structure is similar, but exchanges can differ in available pairs, contract specifications, leverage limits, funding parameters, and risk tiers.
Always check the specific contract you're trading.
Conclusion: Understanding USDC-M Futures on Bitunix
USDC-M Futures give traders another stablecoin-based margin and settlement option on Bitunix. Instead of using USDT, traders can use USDC as collateral and receive PnL in USDC, which can simplify accounting for portfolios already managed in USDC.
The second major update is the increase in maximum leverage for BTC/USDT and ETH/USDT perpetual futures to 200x, subject to applicable risk limits. Higher leverage can increase capital efficiency, but it also makes position sizing and margin management more important.
For anyone trading perpetual futures, the useful starting point isn't the maximum leverage number. Check the margin asset, position size, liquidation mechanics, funding rate, and contract specifications first. That gives you a clearer picture of how the position actually behaves once it's live.
