ye, that's the first thing you should not do, saying "hey guys, i have a lot of money and i'm scared of thief, what should i do?"
Be wise and smart, never ever give out this kind of information in primis then, take all the precaution to keep your coins safe (you got already many great advices in this topic).
Hardware wallet it's the way to go, even better if you can put it in a bank safe but really, do not shout that you have a lot of money, there are a lot of greedy people around.
