It would be good training for those who have never taken the plunge of investing before.
I do know several people who invest and it takes about ten years before you start to get good at it, so I wouldn’t do much more in the beginning than put your money in safe stocks, ones that are not likely going to go bankrupt soon.
However to learn, you have to play the game and that means putting real money where you will likely lose it all. However, that money is the price you pay to learn the rules. Almost everybody here has lost a fair bit of money learning how to invest.
I’ve been in it a bit more than ten years. Still not making much money but losing a lot less than I used to.
Half the battle is gaining Knowledge, the other half is learning how to control the emotions. Im going to keep at it until I either kick the bucket or make money one or the other.
