Pocket money, or the money that someone gives you will only bring you unrest mind if you plan to invest with such money, it's the type of money you are not ready to lose, because it's all you have, because you have no other money coming from else where.
You don't need Bitcoin first, What you need is a JOB, work on that first.
Although I agree with the views you are trying to narrate, but it never hurts for anyone to buy bitcoins with the pocket money they have. Bitcoin can be purchased according to the capacity of money that is owned and is not forced, what needs to be emphasized is the knowledge about bitcoin that some beginners must understand beforehand if they want to be involved in investing. If you can do both at the same time, it will be much better and if you don't have a job but someone has a large pocket money, there is nothing wrong with getting involved in investing.
The most important thing is being able to be responsible for the investment that is being undertaken and not neglecting other needs first. For example if they are still students or students, the money must be used first to support their education and the rest can be used for investment in the simplest way possible.
