Use some hardware wallet or any trusted offline wallet, this way, you could secure your bitcoin to the fullest, also to assure yourself so you don't have to worry about it all the time getting steal by someone. Don't fully trust the online web wallets out there, because they are too vulnerable to hackers and could easily penetrate.

Unlike the hardware wallets, you are the only one who knows the private key and it couldn't be hacked since it is offline most of the time.
