Investments are a way of inviting your friends to come and join you on Millionaire City. There should be an icon for you to click into and begin your investment.
First, you need to send your investment request to a friend.
Second, you should publish a reminder in your investment portfolio so that your friend can notice your request.
Third, if your friend accepts your request, you will find your friends income data in your investment portfolio. You can check if your friend declines it too in the investment portfolio.
For more enquiries, you can literally press the help button in the investment icon.
