Your argument makes no sense, and someone that don’t know what financial situation means shouldn’t be giving investment advice. You’re basically saying investor situation does not matter, at the same time telling them to figure out their discretionary income before investing. Think about it??
How do you think a person figures out discretionary income? The moment you say someone should first identify their discretionary income, you’ve already brought their “financial situation” into the discussion. Discretionary income is determined by a person income, expenses and financial obligation. Two people can can both DCA, but their available amount, frequency and ability to sustain that accumulation can be completely different.
You just want to confuse people with your rhetoric with this idea of financial situation. If I can figure out my discretionary income, why do I have to turn it into financial situation that is vague and sound more of an excuse than anything. When an investor receive inflow like salary, the moment he is able to remove the money for his basic needs, whatever is left is the discretionary income. After arriving at this point, it become easier for the investor to begin to allocate funds into investment, emergency funds and other protective funds. The process have to be easy and not subjective and complicated.
The issue is sustainability. It’s not enough to say “I have discretionary income, so I should put it all ito Bitcoin”. Part of the money may also need to cover your savings, emergencies and other important needs. If someone puts too much into Bitcoin and later need that money, he may be forced to sell
You seems to be making serious mistakes in your reasoning because I don't see where anyone says that an investor can put all his discretionary income into Bitcoin. It is part of the discretionary income that should be invested into Bitcoin, some part will serve as emergency funds, while some part of it will serve as reserve funds and any other words coined to make the investment process seamless and hassle free.
