For someone like me who is not so technical and quite primitive when it comes to my knowledge of anything related to softwares, I feel scared of hackers ofcourse.  I don't have billions of bitcoins like others but what I have is all I have and so that means the world to me and I'm guessing that a lot out there feels the same way.  If you know your source of living or income is about to be taken away or maybe taken away from you without your knowing then you have every right in the world to feel afraid but it is also a cause for tou to start acting vigilant.  
Start by making sure you do not have all of your honey in one pot, store it into barious pots and store your pots into barious cupboards if you want to be extra cautious.  Then, make sure that the keys to these cupboards are well protected to the point that you vould have them encrypted for your peace of mind.  If you are to give someone yoir password or key, be confident that whoever it is that you're giving it to is someone you trust with your life too.  So there, really, acting bigilant is one big step to take as part of being afraid of hackers.  it's a must because otherwise, you'll end up like a crybaby.
