There are so many ways of securing your BTC.
Getting a wallet like Electrum makes it so no one can send money out without a password.
Storing your wallet in cold storage makes it so it's not accessible from the internet (only by your computer).
People store wallets on USB keys that remain in a safe, but then you have the inconvenience of accessing your coins when in need.

It's really all about a security vs. convenience tradeoff, but overall some very solid ways of keeping your coins safe!
