It sounds like you're referring to a promotion or reward on Binance — possibly something like receiving a free "Banana" token or a $10USTD reward using a code like kup10.

However, please be cautious:

Always verify promotions directly on Binance's official website or app.

Avoid clicking suspicious links or entering promo codes from untrusted sources.

Binance sometimes has campaigns involving tokens like "Banana" (e.g., BANANA from ApeSwas), but rewards should only be claimed through official channels.
