For those who are investing for the long term, an emergency fund is important to avoid being forced to sell in unexpected situations. Generally, every investor is asked to keep an amount equivalent to three to six months of income in an emergency fund, but this amount may vary from person to person. The main thing is to have an emergency fund at a level that will not force you to sell Bitcoin. Therefore, it is important to create an emergency fund along with maintaining investment discipline in long-term investments.
That sounds ideal, but real life does not always work out the way we expect. No one can predict what kind of emergency they might face or how much money they will need to get through it. If we knew exactly how much money we would need and what situation we were going to face, then it would not be an emergency.
So if your emergency fund is not enough, selling Bitcoin should not be seen as a failure. After all, Bitcoin is just money, and money is meant to serve our lives.
