Encrypting the wallet
"If you use Bitcoins, you have the option to encrypt your wallet" - that's a bit misleading. The present version of the officieal Bitcoin client does not have the option to encrypt the wallet. Silly, isn't it? For a developer of a crypto currency to keep the wallet unencrypted... All you can do is create an encrypted disk partition and tell the software to keep the wallet file there - which is rather inconvenient.
BTW, how do you call a pickpocket who steals your Bitcoin wallet? A "bitpocket"?
