I want to buy miracle coin with the money that is already in the wallet of the play store, but this option does not appear. When I hit '' Google Play '', it appears to use either credit card, Paid Marketplace or gift card. Can I use my own Play Store wallet to buy Miracle Coin? I already downloaded the official app for this link: https://play.google.com/store/apps/details?id=com.aigrind.warspear
