You don't need to have a stable income before you start investing into bitcoin, you can start with what ever amount you have, waiting to stabilise before investing in Bitcoin is not the right thign to do cause you can start while you put yourself in a better position by looking for a stable source of income, let's assume a guy that receives 100$ as a birthday gift and wants to buy bitcoin, although it's it's a steady income he can decide to invest up to 50$ into bitcoin or less depending on his expenses and what matters most is taht he has already started and when he has another money he can buy again and by the time he is stable he might already have some money invested into bitcoin, besides it's a long term approach so he has time to fix himself as he accumulates bitcoin.
Having a stable source of income is crucial for consistent Bitcoin accumulation while also meeting personal needs. investing money you have at the moment without having a steble source of income can impact negatively and hinder your Bitcoin investment growth. Bitcoin investment requires one to be engaged in something that brings earnings or wages either weekly or monthly so that certain percentage can be allocated to your Bitcoin investment no matter how little it may be and also doing it consistently, whether weekly or monthly, to ensure steady growth in your investments. Consistency is key in building your Bitcoin portfolio while balancing your financial responsibilities. It's all about finding that balance and staying committed to your investment goals.
It is applicable only to those investors who are very serious about their investment and who do not want to disturb the continuity of investment in any way. But I think that an investor can continue to invest properly as long as he doesn't feel too much pressure on his investment. Whenever an investor feels investment pressure he will not be satisfied with his investment and will feel that he should sell this investment. So the investor will invest according to his ability and when he gets time to invest he will invest so that even if the investment is not continuous he can hold his investment for a long time.
