Notes

• Generators produce rewards periodically until the end of the month
• Rewards depend on the upgrade level
• No need to collect your rewards on time: they will stack and can be retrieved anytime
• Uncollected rewards are sent by mail once the generators disappear
• No need to rush the first minutes: you receive full rewards for the ongoing period you invest in
• But if you miss the first period completely, your rewards will be reduced
