No good investor that will see emergency fund as something to play with in as much as having the intention to hold long term is the aim of that investor, because is not a matter of using it and later replace back reason been that emergency is unforseen circumstances that can't give you sign before it take place
The example I gave in my post above is clear for you to know that a delay in someone's weekly or monthly salary payment is a good emergency that will make that person use his emergency fund to cover up until the person receives his salary. For instance, you used to receive your monthly payment at the end of each month, but something happened at the place of your work, and you got paid on the 10th of the new month. You will have no choice but to use your emergency fund to sort out your bills because you never expected that your salary payment would be delayed.
If challenges like salary payment or other challenges comes up an investor can always rely on their floating or reserve funds till further notice, an investor can decide to build their emergency funds depend on their income and choice but, I personally build my emergency funds time to time cause it stands as an alternative not because I want to withdraw each time I encounter challenges. An emergency funds can always stand and accessible, it’s not proper using your emergency funds always settling every needs without replacing back the money, emergency funds is not meant to stay empty rather build this fund along side with your invest is important. When gotten to a balanced portfolio with your investment (mature investment) an investor can diversify, All this depend on an investor planning and income.
Emergency funds should not be tampered with or used for your needs, and being replaced back. Emergency funds is always there as stand by at all the time and not to be spent only when a real emergency happens. For instance, if you lost your job, you can rely on your emergency funds for the mean time till you get another job, so that you don't sell for bitcoin to survive during when you don't have a job. Your income should be divided, whereby you have set aside for your needs.
If a real emergency happens, and you use the funds like the example, I gave above, when you get a new job, you can then replace/build back your emergency funds. This is why we should have a good size of emergency funds, so that whatever emergency that happens, it can sustain us. It is also good because that is what will also consider how aggressive we will be when accumulating bitcoin through DCA in a particular time.
