If an investor cannot keep an emergency fund or a reserve fund (backup fund), then he will put his investment at risk. Because an emergency fund is kept for danger. If an investor gets into danger while running his investment and there is no one to help him. Then if he has to sell the investment to get rid of that danger, then he will have no end of regrets. You can face many obstacles and dangers while investing. Therefore, an emergency fund or a reserve fund is necessary to deal with any emergency situation.
You right @Lembo69 it is very important we setup an Emergency funds alongside our Bitcoin investment. I also understand that Emergency funds are setup to protect our investments in Bitcoin and to also prevent us from tampering with it whenever future real life Emergencies happens. If we wanna look at it from this very angle,you will agree with me that Emergency funds sometimes may not be enough to protect our Bitcoin investment 100% because there are some serious Emergencies situations that are bigger than what our emergency funds can solved. In other ways to counter situation like this, we should try as a much as possible to build a stronger Emergency funds that can handle bigger Emergencies.
However As investors our discretional income differs in sizes, likewise the low income earners who's discretional income isn't that big should consider building and funding their emergency reserved consistently for At least a period of 1 Year in other to have a stronger Emergency funds that is capable of handling bigger real life Emergencies situations.
