If I wouldn't have a choice but to sell my Bitcoin then I would do it. I can't starve my family so I could keep holding. There are still opportunities for me to earn and buy Bitcoin again but if the situation would ask me to sell it, I will never have a second thought of doing it if its really needed. Holding Bitcoin is really important as an asset and investment but we can't disregard the fact that we still need money to sustain our needs.
Bitcoin is very important asset because we consider it as precious as gold and land lots and we hold it as investments to gain more profit in the near future. But we should have not to forget that we strive to earn and improve financially for our self and family, then as for my own opinion, there is no reason to hold our assets that we prepare for the future if it is much reasonably needed by now. As the sayings said "what's the sense of the grass if the horse is already dead".
