This is very shocking to me that an investor in Bitcoin will not have an Emergency funds nor see it as mandatory.I can't even imagine myself not having an emergency funds or a backup funds in this regard because it's not Idealistic at all. Am sure an investor who doesn't plan on building an emergency funds plans to fail because there's absolutely no way he wouldn't consider having an emergency funds or backup funds if he truly plans on succeeding in his Bitcoin investment. It's very mandatory or highly commended for an investor to start building his emergency funds using his discretional income for the next six months to keeps his Bitcoin investment protected .

Another facts here is that traders that gambles or  are already gambling with their Bitcoin investment always shares this common view that having an emergency funds is not mandatory
maybe for traders alone since there are into a short term plan [Buying & selling] makes it more optional for them but doesn't apply to an investor with a long term plan.
