Anybody that uses funds for emergencies to invest in Bitcoin is not a wise investor because problems can come at anytime when he/she will need some money that he will use to settle down some things that needs to be settled..
Having an emergency funds might make an investor to hold more longer than he or she planned to hold. Reasons are because when you are saving and still accumulating Bitcoin and on the other hand you have funds for emergencies, then what will the person want to sell his coins for? Nothing,,, unless they will want to use some of the profits to complete a project and other things that can be bring more money to them during the week or month.
There are some people who works in a company that don't pay workers salaries on time (delays payments) and those people if they are invest in Bitcoin and they are not saving some funds for emergencies and just saving for nothing, by the time month end and there is no payment they will want to sell some coins and use the money to support them self untill payment is made.
I have not seen anyone keeping funds for emergency. There is no special emergency funds in anywhere but the funds came out when the emergency arise. Nobody pray for bad omen or danger ahead, but emergency is unavoidable, whether we like it or not we must encountered it from one way to another and emergency funds also comes unprepared. And at that time of the emergency, no responsible person would use that funds to invest in Bitcoin then the person does not value the sick person life. Bitcoin is not something we invest and reap within a second or hours. But a long term investment.
As I said nobody saves money for accident, law case and others but it is when the matters arise then money would come out from it hidden places to settle the problem.
