nice reed and funny to boot. 
Just a question. sorry i am very new in theese thinks. my onyl worry the nowdays we can hear about lot of hackers, what if somebody break into my system and just still my wallet number? can this happen? what can you do to avoid this?
Well that is the point of this thread. I somebody gets a copy of your unencrypted wallet.dat they can copy it somewhere else and have access to your funds for ever
. Only way to avoid that is creating the wallet on a clean installed system without a persistent file system (ie: Live CD) and copying the wallet.dat to a memory stick or pendrive that would never be use in your day to day computer. As the objective of this is creating a savings account what you do is take note of the addresses created in the clean system and send your bitcoins to those address from your regular computer. When you want to take money from your savings account you load a clean system again (Live CD once again), load your backed up wallet.dat, send your money to wherever you want and shutdown the system without leaving a trace.
Hope this helps.
