The maximum amount you can borrow are determined by 3 factors: The available borrowings based on your crypto holdings in margin trading of your account, the max borrowing amount based on the tier of your main or margin limits, and whichever is less. For more information on margin rules and tiers, please refer to:margin borrowing position tiers
1. Alice has 600,000 USDT for BTC/USDT trading. 3x leverage lets her borrow 1,200,000 USDT more. Because of the borrowing limit, the maximum amount Alice can borrow is 1,000,000 USDT.
2. Bob has 200,000 USDT for BTC/USDT trading. 3x leverage lets him borrow 400,000 USDT more because this amount doesn’t exceed the borrowing limit.
Note that the individual maximum borrowing limit vary by trading pairs. Even if you’ve borrowed 1,000,000 USDT for BTC/USDT trading, you can still borrow extra 500,000 USDT for XRP/USDT trading. To minimize your risks, we also consider other factors when calculating the limit. You can find the final amount on the margin trading page.
