You don't need Bitcoin first, What you need is a JOB, work on that first.
The point is that finance is not forbidding it, but limiting it and making sure to make any decisions based on numbers, not emotions. I understand a little what the OP said, and I think it's not only newbies who have to carry out suggestions like this, those who are not beginners should also implement a system like this. Because bitcoin is an asset that is used for investment if you don't have a job, how do we start investing? by way of debt? this will worsen our finances.
The way I understand @OP concept is that one must have a stable job before investing in bitcoin, which I fully agree. If there is no one supporting a person and he is only by himself, any investment on Bitcoin will be a waste if he don't have a steady source of income because in time when he has nothing left, he will be forced to sell his holding prematurely which may cause losses.
The mindset must be changed, don't buy Bitcoin expecting to get rich in a short time, but buying bitcoin means we are ready to lose money. Therefore, what is needed first is not to buy bitcoin, but how do we find work, that way 30% of the money we get from our new job buys bitcoin in stages every time we receive a salary from work.
Regardless, invest only when one is able to support himself without touching his investment. This way, the person has all the time to wait for his investment to produce profit.
