I think almost all of us who uses bitcoin  do also experienced it because we are only humans and we arent perfect. And if that happens to me, I will not know what will I do. surely many people who have experienced such an event, and of course we really do not want it to happen to us but want how else
such events come to anyone and without any notice of course so with the incident we are required to be more vigilant and careful in doing something.This will serve as a learning to all bitcoin.
