Yes, that means there is no hot wallet on the servers, I have the wallet on my computer, and there are digital and paper backup of the wallet in case something happen to my computer (we use the very secure Armory client and its awesome watch-only wallet feature to track deposits on Bitfinex side).

In other word, if a hacker manage to find an access to the servers, he won't be able to steal your bitcoins. That doesn't mean we don't take care of the security of our servers though .

On your side, don't forget to use google authentication if you can, and if you want, we can make an arrangement so that I proceed your withdrawal request only if I receive a confirmation by email from you.
