Selling digital gift cards like a $300 Razer Gold balance is a common way to earn US dollars in Nigeria by using specialized online exchange platforms.

To proceed, you must first create an account on a trusted site such as Redemption Center or ExBuyer and navigate to the gift card selling section to input your card details.
After the platform verifies the $300 balance, the funds are typically deposited into your Payoneer account or digital wallet, allowing you to convert the dollars into Nigerian Naira.
