I also plan to use my emergency fund for my child's needs, as he will start school in about a year, and I can use my emergency fund for future needs and beyond as much as possible without having to use Bitcoin prematurely.
Indeed it is correct that everyone should clearly remember about a separate savings section as the emergency fund is like a financial safety net. Using an emergency fund for a child's needs doesn't seem like a complete healthy plan to me and this plan should be shut down immediately. In terminology it can be said that these things are basically part of your financial plan so it may be appropriate to use personal savings or other reserve savings to enter at that moment. In fact an emergency fund may not be created to cover such expenses, basically everyone tries to save that money to deal with unexpected and confusing financial pressures. It's true that if you don't want to use Bitcoin prematurely, so definitely need to find other options or alternatives but you probably shouldn't touch your emergency fund at all because these funds should be used properly based on risk tolerance and for unexpected moments.
To be honest with you, i didn't have the ideas of creating out emergency fund more of have a discretionary income to use for an investment but ever since i joined this forum i have learnt allot in the forum and this discretionary income i have use it to invest instead of saving it in the bank and it is in this forum that i understand how important emergency fund it is, ever since i have be practicing using my discretionary income for investment and emergency fund that can be of help to me not touch my discretionary income incase of any unforeseen circumstances and i have also spread it outside Bitcoin investments too, so as I'm investing and with emergency fund, I'm also having emergency fund outside my investment.
