Let's bear in mind that emergency is something that comes unexpectedly and most time can be very life threatening.
so it may be a matter of life and death and if so anything can happen.
if in the emergency situation you are able to see money to borrow and you are sure of paying back without any problem, then you go ahead and keep holding your bitcoin but if not, I will advice you sell and save your life first, and that's if the emergency is life threatening.
remember that health is wealth and it's the living that invests and holds.
Some people are saying the things they are saying now because they are have not experienced what's called emergency before. I have once sold my laptop and phone for price below the amount that I bought them to save a friend that had an accident in school during school rag day, it was a trailer that push their truck to the bush, we have to do what's necessary before we could even tell the parents as the mother is having high BP, we couldn't tell her immediately.
Things happened not because we want them to happen or not because we are not ready for it, they come unaware and sometimes you can be unprepared. You can save emergency funds for 4 years and it's possible you may not encounter any challenge of any such but as soon as you use that money for another things, you may encounter an emergency condition the second week after using the money, life can be uncertain and unpredictable.
