The emergency funds should not be used for your bitcoin investment or accumulations, your emergency funds which should be able to cover at least 3 to 6 months of your financial expenses should be able to take care of your medical bills, payment of your utility bills and other financial obligations and not to be used for your bitcoin accumulation.
These are not emergencies but part of your expenses which you should've considered and removed them from the total income before considering the remnants your discretionary income, I might consider the first one "Medical expenses" as an emergency if there is a big medical challenge and not routine checkups or common illnesses that are non-concurrent, but are not emergencies.
The coverage of your emergency funds is subject to a real emergency occurring like car accident, fire accidents in the home and you need to replace some properties ASAP and other things that are that aren't expected to happen. Another scenarios is in the event you are cut off from your income all of a sudden without prior notice and you have exhausted all your savings, then your survival becomes an emergency and you can survive on your emergency fund for the time being while you work on fixing your finances and rebuilding the funds you depleted while you were financially backward.
That's so true. People often confuse what is an emergency fund and what is a necessity. All kinds of things can go wrong in life. There is insurance for these, but insurance does not cover every eventuality and you may have to make unforeseen expenses. Life is unpredictable, so it is always important to keep some money aside.
Putting that aside, you have a good income, your expenses are less than your income, you have a good level of emergency savings, you have done your basic consumption shopping, the next step is luxury consumption. The more you cut down on that luxury consumption, the more you can invest in the future. In this case, the first thing that comes to my mind, and probably almost everyone in this forum, is Bitcoin. In this case, you can make purchases to increase your Bitcoin amount with peace of mind.
