Any suggestion for things that we could invest and make money at the same time
You have been a little bit late for your investment, the price pumps a little. If you want to put some investment you can look on some ICO's that is currently doing their sale, but make sure you are scanned it very well, you should look for their whitepaper and the team behind it although it will took time but it can lessen the risk that you may encounter.
It is not too late though. The price just started pumping and there is a lot of space the price can grow. But before he starts investing, he should know the fundamentals first of the coins he wants to invest in. If he blindly follows all the suggestions here, that can end very badly for him.
