To invest in Bitcoin, you definitely need a sensible income, why can't you invest and move forward if you have a mirror and don't have a good source of income. To invest in Bitcoin, you definitely have to be wealthy. A low-income person can invest in Bitcoin if he has the mindset and desire to invest. That's why it's most important to invest in Bitcoin according to the DCA method, because the DCA method is easy for any person and investing in Bitcoin is most important for him to further secure his future through income.
Your statement seems to be very misleading, because you’re sounding all confused, well
I don’t really know what you mean by sensible income, but to my understanding you just need a discretionary income to invest in bitcoin and decide to hold for a long term interval.
However you don’t need a good source of income, what you should endeavor to have is a discretionary income and this money that could be used for whatever purpose but you have to decide to invest that money into bitcoin, and you don’t have to be wealthy to invest into bitcoin, you can start investing into bitcoin little by little on a regular basis and that would be more efficient.
But I must say that you’re mixing things up and you sound confused with your statement for saying you need to be wealthy to invest into bitcoin, and latar saying that a low income earner can still invest into bitcoin, well I must say that you sound confused.
I agree with you that you don't need to be rich to invest in Bitcoin. You can start with a small income if you want. But you can also think that if you have a stable source of income, deep buying will be more convenient. Since this is a long-term investment system, you can think of it like the stronger the roots of a tree, the better the growth of that tree. You must be patient. Don't get discouraged. Take your time, observe, learn and apply.
