Before than you listen to any advice you should start thinking in a completely different way with regard to cryptocurrency. When you are in possession of BTC or any other coin you actually become a bank, and you know in what way banks protect funds of their clients. Even more difficult is to protect something so sensitive such as cryptocurrency, so before you acquire new coins take some time to learn about best wallets and security.

Many are skeptical about hardware wallets, some say they are not safe or they are too too expensive, but this is not true. You lost 0.312 BTC which is today around 1400$, and hardware wallet which would save your coins cost less then 100$. This is small price to pay for security of your coins in the future, and certainly the great saving of time in case you want to try some other ways of safe storage - buy&use and be safe.
