Value written on your Planet NFT card represent the minimum income you can get on a monthly basis.
When you complete the 2 weekly tasks you will get 1 multiplier. You earn an additional multiplier by doing the tasks that will be announced at certain intervals.
For example, you saw the value 30 in Planet card NFT you have. When you complete the 2 weekly tasks, you will earn 30 USDT per month. If you increase your multiplier to 2 by completing additional tasks, you will get 302 = 60 USDT per month.
Planet owners who verify their planets and complete missions will automatically receive USDT payment within 2 WEEKS. So you get 2 payments every month.
