While that's true. It's also worth noting that not all unexpected expenses are actual emergencies, that's why it's also advisable to have other backup funds asides the emergency fund, just like the reserve fund and also the float fund, this could also be used to cover some unexpected expenses which are not actually an emergency, so that the emergency fund will always be reserved until when an actual emergency occurs.
Emergency is emergency bro when Challenges you never expected hits you it's called an emergency maybe the unexpected expenses you are talking about is for example maybe you dey go buy food stuff for market and you no expect to give out money to people you just budgeted money for food stuff only and some one or an old friend now ask you for money and you gave out I believe that's the kind of unexpected expenses you are talking about.
I don't think that's the type emergency we are talking about real emergency could be burial in Nigeria you already know that people spend whole lots of money when it comes to burial this is just an example of the kind of emergency fund we are talking about not road side expected expenses.
So the expected emergency you are referring to is not the real emergency when it comes to bitcoin investment.
No, I don't buy the idea that emergency is emergency, their are level to everything, and emergencies are in levels, just as you illustrated above, someone or an old time friend you met in the market beg you for money comes with different pressure to health emergency, in the case of your old time friend begging you for money, you can sort that out with your reserve funds because it's the money set aside to service your Bitcoin investment either by using it to buy aggressively during the dip or used to sort out one or two vital needs or expenses that a not part of your basic needs.
But our emergency funds should only be used for real life emergencies that threatens your Bitcoin holds, something huge not minor needs or expenses that are not part of our basic needs, something like health issues.
