it's not a free giveaway, it's a loan with temporarily waived interest.

Here’s what’s actually happening:

You are borrowing up to 50 USDC from Binance under their Cross Margin feature.

For 1 day only, no interest is charged (this is the “voucher” benefit).

After that 1-day reward period ends, interest starts accruing at the regular rate unless you repay the loan.

You must have sufficient collateral to borrow.

So think of the voucher as a short-term interest-free loan, not free money or a gift. If you don’t repay it within that one day, you start paying interest like any normal margin loan.
