I am currently exchanging back to USDT, but the exchange is directly failing. What is the reason for this? If it fails, will my gas fee be refunded or will it be deducted directly?

Note: The event is at UTC+8:00: Exchange starts at 00:00 on the 30th.
The Binance Wallet team has launched the 'Trade on DEX with CEX funds' feature, and the Binance Wallet will host a Bedrock (BR) token airdrop event this Sunday!

Event time: From 00:00 on March 30, 2025 (UTC+8:00) to 00:00 on March 31, 2025 (UTC+8:00). There are 100,000 spots available, so everyone hurry up! Both big and small rewards are still rewards.
