In otherwise, the emergency fund saved to tackle occurance of emergency challenges can turnout to be a capital for a new investment if proper planning are put in place instead of saving the fund somewhere without it adding interest.
then that's obviously not emergency fund. Proper planning entails you keep emergency fund and not tamper with it or else the real emergency will come at the time you least expect. While making your plans, putting things in their proper perspective is almost as important as making the investment in the first place. No doubt, an alternative investment opportunity might erupt along the line and it might appear as though your emergency fund is laying waste and could possibly go into that alternative investment and yield more profit but just know that you're at that situation that demands you to become matured enough to see certain things as major distractions. It's not wrong that if you have another money outside of your emergency funds and sees an opportunity to invest into, that's a totally different situation, but when you go on to using your emergency fund for another purpose, then you've literally mismanaged your fund and it will certainly affect your investment.
For instance, if there is a total some of $150k save as emergency fund to help tackle emergency challenges, a good investor and business oriented minded person can use part of this money to accumulate Bitcoin using DCA strategies for a long term investment and then be accruing the profit of the investment to emergency challenges and within little time in the near future there may be a reasonable rate of return from the little investment made from emergency fund.
maybe you're getting somany things twisted here and it's possible you don't know the value of the figure you're putting out here.
For clarity, 1
BTC at the moment is just $61k and if we do our little maths, with that $150k you are looking at using for emergency fund, you can starch at least 2
BTC and still have $28k left. Except you're a extremely rich, using $150k as an emergency fund doesn't look wise at all, I mean, how much have you ever as starched up before having such reserve that's going up for emergency fund? Let's be realistic sometimes.
