If I had many bitcoins I guess I would be afraid, but since I am poor junky who hopes to become reach through cryptos , at this time there is nothing to steal 
no worries junky, day will come that your portfolio will also grow and you'll fear both from hackers and risk of market crash. I also don't have much but that's all I have and some of my friends wallets has been hacked. so if I say that I am not afraid, that wouldn't be true.
