Not having a stable source of income of income shouldn't stop an investor from starting to accumulate bitcoin, the most important thing is if they have discretionary income to invest with and once they have sort out there discretionary income after meeting all there expenses there is no need while they should be waiting to stabilise there income .An investor can be investing in bitcoin using discretionary income and at the same time while working to stabilise his or her source of income. What an investor needs to Start accumulating bitcoin is discretionary income and not stable source of income. Even with a stable source of income without discretionary income an investor is not fit to invest in bitcoin since the investor will be investing money that is meant for expenses into bitcoin which is gambling.
First you need a stable source of income then discretionary funds to be able to sustain DCA method, without both there is no how you can accumulate and hodl. This means that a jobless person and a struggling person that is working but cannot cater for their basic needs should not go into Bitcoin investment because it will be unproductive attempt.
I disagree with you on this bro, someone may not have a stable source of income, but have discretionary income at the end of the day, possibly someone who's income is not very stable might have less expenses to take care of and as a result still have a good discretionary income after taking care of his little expenses, such a person should not wait to stabilize his income first, but jump in with his part of his discretionary income and start accumulating bitcoin consistently and with commitment while building out backup funds alongside their accumulating bitcoin.
Someone can also get a lucky win from lottery or jackpot and after settling his expenses and still have some good income left, the person can still put it into bitcoin. You must not figure out everything before getting into bitcoin, you only have to get started first with available discretionary income and as you progress into your accumulation journey, you may start getting lots of maturity and stability in your income and handling your portfolio properly. It might interest you that some people would even be pushed to do more about their income when they are committed to accumulating bitcoin.
