Let's say I have paper wallet "X" and paper wallet "Y". I also have a wallet for spending: wallet "Z"
I want to transfer 0.01Bitcoins from "X" to "Z" spend 0.005BTC and from there send the left over 0.005BTC to "Y".
When I took the funds out of "X" I used the password "12345abcde" (which is BIP38 encrypted) and now that the 0.005BTC are in "Y" the password (which is BIP38 encrypted as well) is also "12345abcde. If I had malware and/or a keylogger are my funds at risk because the passwords are the same?
Question 2.
What ultra-paranoid method do you use to store large amounts of BTC? Why do you trust it and how is it 99.999% safe?
I'm just being ultra paranoid because when I started with Bitcoins I got hacked in under 24h. Mind you I was using the Blockchain.info android wallet so that was pretty newbie of me
.I know some people here: https://bitcointalksearch.org/topic/time-to-bust-a-myth-paper-wallets-are-less-secure-than-normal-encrypted-wallets-1013586 feel that paper wallets aren't actually as secure as they might seem. Just because you use a Ubuntu Live CD/USB doesn't mean if you had malware on your Windows system it won't also be able to infect the Ubuntu Live CD/USB.
This is very top-notch ultra-paranoid stuff and I'd love to hear your expert opinion on the subject!
