The key is make sure you're only invest amount that you can afford to lose and you will not touch it, many people are really focus to invest all of their money and then after few days or weeks they will ask "should I sell my coins now for urgent needs?".
If you lack of money and live from paycheck to paycheck, it means you need to find a high paying job first.
If it were easy to find a high-paying job, not everyone would have difficulties in life, and people wouldn't have to work hard to find new solutions. We don't need to find a high-paying job, we just need to put in a little extra effort like doing side jobs to increase our income and then plan to invest in bitcoin.
I agree that we should prioritize family life needs over investments, but maybe investing is an opportunity for us to overcome the current situation. Therefore, we must trade off a little instead of always thinking we need stability before investing. Because if we have achieved economic stability, do we still need to invest?
