It's an interactive tool we created to reward you and give you the opportunity to enjoy our new products. Depending on the activity or your participation on the Binance platform, we'll send different types of vouchers to your Reward Center. The cash voucher is an airdrop that will be credited to your corresponding account once you redeem it. It can be used for various products (spot, margin, futures, P2P, etc.). The cashback voucher can be used for deductions in trading fees.
