I look at bitcoin as my early retirement fund. Obviously, none of us want nor expect a significant crash and loss of value from which Bitcoin will never recover.
I am sure that quite a lot of bitcoiners who have been in the network for a lot of time also look at bitcoin in the very same way. Bitcoin is volatile, but since it is a retirement fund, it is a very long term investment depending on the age of the individual, and bitcoin does so well in the long run, neither is it going to go to zero.
