The transfer of gold from tanks to doubloons is possible, provided the following conditions apply:
1). Gold purchased by the owner (it is not essential what was purchased, essential is the act of purchase), (TN: i.e. bought for real money alone, or as part of a bundle;)
2). Not gold awarded as prizes, offerings or gifts (e.g., in competitions);
3). The minimal amount of transfer: 2,500 gold/doubloons;
4). At least one month of inactivity in the game where the gold comes from, (TN: i.e. have not played tanks or planes since at least one month;)
5). One transfer per account only.
