I received a token voucher from a BSC campaign reward. It was worth 0.00021 BNB and could be used in the Spot market. I used the voucher on May 12, 2025, at 5:38 PM (UTC +5.5). The status now shows "Used," which means I have already claimed it. These kinds of vouchers are usually given as part of promotions or rewards. They can be used for trading or other activities on the Binance platform. I'm glad I received this small reward as part of the campaign.
