Lately, the exchange has been generous, giving out many transaction fee refund vouchers. I'm currently using one, and the exchange gave me another voucher.
Each voucher gives a $30 USDT transaction fee refund. The only downside is that the duration is a bit short, around 3-4 days until expiration.
But that's still great, haha.
I check the Reward Station every day to see if I got any vouchers, haha.
There was also a time when the exchange rewarded me with USDC to use.
