I agree with you that emergency fund is our back bone when unforseen circumstances happen, but I think it not compulsory that emergency fund must be 3 to 6 months ahead of our salary. I feel that discretion fund should be in position to be higher than emergency fund. reason because emergency don't happen frequently Rather regular expenses occure more frequently which will require discretion fund rather than emergency fund. Emergency fund don't need to be tamperd always or frequently like the discretion fund. If emergency fund is much higher than discretion fund then some regular ppl problem will be considered as emergency and will leed to always tampering emergency fund. But if discretion is higher than emergency them some problem that may even appear as emergency may be solved with discretion fund. Always considered discretion as a middle man between Bitcoin investment, emergency and family expenses.
I find your description confusing, since none of us have been talking about a discretion fund.. which sounds like a reserve fund.
The idea of discretionary income is the amount of money that we have available after expenses... so with discretionary income we can choose to invest or to consume with it or to save it by putting it into an emergency fund and/or reserves.
Generally, the emergency funds are the amount of money that we would not touch absent an actual emergency, but yeah, if we run out of reserves and other kinds of extra money, we might be forced to tap into our emergency funds, which would be our last line of defense before we might need to tap into our bitcoin investment.
Thanks for putting this confusing concepts between emergency funds and discretionary funds into perspective, the simple fact is that emergency funds is gotten from discretionary funds. When you remove money for fixed expenses like food and rent, the rest of your income are at your discretion to know how to spend it, it is from there that emergency funds can be taken out. This is why it is said that we remove funds from our discretionary funds for our DCA method of accumulating Bitcoin. It is from the discretionary funds that we can put money aside for savings and other short term financial goals.
A person that understands financial management coupled with Bitcoin knowledge will know how to make budget and know the percentage of money that they will take from their discretionary funds to buy Bitcoin that will be sustainable in their DCA strategy. It is good to make provisions for emergency funds and savings, not concentrating most of the discretionary funds on DCA. Without proper planing the investor will sell their Bitcoin prematurely because there is no adequate provisions for emergency expenses.
