I doubt that you are making any meaningful and/or important point OrbitalX - since the ways that guys use either term would depend upon the context inht which he is using such term... so at first there were guys who were seeming to proclaim that guys should not be investing into bitcoin unless they have a steady income (which they might have had referred to as a source of income or source income.. either way).
Something else to ponder here, I don’t necessarily agree with you can’t invest in bitcoin if you have no income source.
When you consider your emergency funds include your dca amount as per the term; 3,6,9,12,18 etc months of funding/living. Technically you don’t have an income but you planned for the worst and can continue to DCA too with the emergency funds include kicking in, in your time of need.
While I am finding it difficult to understand this statement I bolded out, and I would point out straight up that if you do not have an income source
not necessarily a steady one, then you may not be able to have discretionary income since funds are not coming in from anywhere and you do not have hope of any.
If you have been having income and it has been cut off momentarily and you have expended all your variances of reserve funds, leaving only your emergency funds, then it surely makes no sense to buy bitcoin from your emergency funds since you are in the red zone of your finances. More focus should be on fixing your finances possibly before your emergency funds gets depleted and you turn to your holdings for survival. if you continue buying with your emergency fund and it gets drained when you have not fixed your income, at that point even the acquisition you made with your emergency funds might be retrieved at a loss if bitcoin goes into a negative correction at your point of selling.
