By becoming a Supporter, you will be able to obtain extra BillG Coin by forming a security circle of 3-5 trusted individuals. After you've completed three mining meetings as a BillG Coinoneer, the Supporter job becomes available to clients. After 3 days of mining, you'll see a new icon of the security circle on the app's home screen, which you can tap to begin. To become a supporter, you must add 3-5 people to your security circle whom you trust.
