The fact remains that the ealier you start taking risk as a student, the strongeer you become to face the world after graduation, for me i will advise you should invest some percentage of the money you save.
The parable is the faster someone moves to do something, the faster he understands something. If in this case you intend to advise someone on an investment, I think it is right to use some percentage of the money you have saved, because it will also be better for him as long as he is very understanding of the risks.
But if he still doesn't really understand the risks and places to invest better, it is also highly recommended for everyone to find out these two things before immediately deciding to invest. Because a good investment is in a place that is really safe and really good and is also carried out in the long term so that the income can be felt more satisfactorily.
