I've been streaming PK battles since 2023, and I've always treated my Diamond balance like ammo. You don't think about the price per bullet until you're out of bullets mid-fight. That night I learned that a likee gift card(https://www.lootbar.com/gift-card/likee-gift-card ) and App Store Credit are not interchangeable currencies — they're two different economies wearing the same logo. One route charges you for Diamonds.
