It would be very myopic for an investor to quit his job just because he invested in Bitcoin, so what's going to be paying his bills till his Bitcoin investment get mature?
Because to the best of my knowledge, anyone that have no source of income has no business investing in Bitcoin because he needs to cater for his basic needs, and if he can't do that, he can't buy and accumulate Bitcoin consistently,
Yes, I agree with you on what you just said above regarding source of income and why it is important for Bitcoin investing, as an avenue to sustain the investor while allowing his/her investment mature in a long term. But one thing I also don't agree is the part where you said accumulate Bitcoin consistently, because it's literally not a must that every investor must accumulate consistently, but it rather a choice for people who have more money to always accumulate more whenever they wishes. Because a person can still no longer have a job and still decide to buy just $20 to $100 worth of Bitcoin and hold it for 15yrs or 20yrs when its price value might have skyrocketed to 100x.
The best form of strategy for Bitcoin investors is to have steady cash flow that help the service their Bitcoin investment at regular intervals, this is so that there won't be pressured into liquidating they previous asset when there is any financial needs around that investors, let say that even though you make at least $100 monthly and you decide to go long term with Bitcoin as you stated, 15 years or so, it hard to be able to attain such height without steady cash flow that allows you to look away from your Bitcoin investment for such a long period of time, its quite alright to say that, putting extra funding like let say additional $20-$50 monthly after the first initial investment amount of $100 or More, this will help you build up you portfolio more and at the same time increases your Bitcoin worth in all direction along the line. With our puting you as an investor under any form of pressure.
