Without cahs flow, you do not have any means of putting money into Bitcoin, even if all your needs are catered for. Anyone joining Bitcoin now to get rich should realize also that the ROI is no where near what it was ten years ago. They would not get lambos with Bitcoin, except they already had a very good source of income.
If you want to get rich, build your income and reduce your expenditures and liabilities, then invest.
One of the comments i have read in this thread, OP might have a rough starting experience in his journey over the years probably because he had little money at the start of his journey but because he still has someone who provides for him it was easy for him to invest the little money he has.
There is no way one can invest in bitcoin without having money now as bitcoin investment is not as it was when it first started so yeah only rich people can make enough money for themselves in bitcoin investment in a short period. It is best for a person to build wealth before investing else one may just end up investing an amount they can’t afford to lose and probably invest due to fear of missing out.
What I am saying here is that it's still doable if you have the conviction to make things happen, if you crave for changes you will go any lent to make things happen in the right manner and ways, but having a source of income will make things more easier for you, I still considered my story as a easy one because I had my father then, I had a roof over my head in my parents home, and also I don't pay any bills, it was just me and my stomach to feed and my BTC wallet to fill up.
For someone who came from poor home it will become a very big battle to conquer poverty, and for those who come from average or rich home, it becomes easier for them to have a better future because they will have more money to take risks, if you are from a home like mine, you need to strive hard, my battle took me three years, if I have never know Bitcoin and I decided to take the path that everyone in my country was into it would have been harder for me, judging from the present conditions of those who almost stopped my Bitcoin journey, I am not shaming anyone, I am just saying that Bitcoin is worth every shot.
Because since the past 12 years, there is no investment that does it better than Bitcoin, you can't find anything like this anywhere else, it's worth every fight and hustle, but your journey will be way easier if you have a source of income, don't give up, always give your best short, you are on the right path.
Your story is quite touching; it takes a strong mind to stay committed and focused when faced with many obstacles along the way. Despite coming from a low-income background, you were able to overcome all of the challenges. However, investing in bitcoin requires money and one cannot invest without it. I know you said you were making a little money through some internet side gigs, which you were able to invest along with your pocket money.
I'm not sure where you're from, but in a typical African home like the one I come from in Nigeria, having pocket money and having been exposed to bitcoin back in the day is considered a blessing. Therefore, if you were from Nigeria, I wouldn't categorise you as coming from a poor family because in my country, people in your situation are considered average earners. Being from a poor family means that you can never earn anything close to pocket money because you have to work for your money in addition to feeding yourself. This is why it's very difficult for people from poor families to invest in bitcoin.
