Isn't the problem keeping the coins in on online wallet or exchange? If you store your personal wallet offline how can you be hacked?

Lots of ways:

- Software you use for key generation uses a known random-seed.

- Compromised software that converts your seed into an address/priv key.

- Compromised transaction generation software.

- Offline wallet physically stolen

- Malware / firmware exploit on USB used to transfer transactions between online & offline computers
