Well if your that paranoid use the paper wallet or brain wallet.
I searched the term brain wallet and all I got was this from LibertyOrDeath. Can someone explain how I can create one,
or several?
I expect a self coded encrypted personal phrase that only a head injury or dementia could erase is the
point?
If a little knowledge is dangerous, then even less is reason enough for paranoia.
Brian wallets are very risky because people hopelessly underestimate the entropy of their pass-phrase.
The most secure way to store Bitcoins is with paper wallets (or something longer lasting like nickel or stainless steel) generated off-line. You should either make two copies and store them in separate locations, or create a multi-signature script/transaction such you need m of n pieces to authorize the transaction (and store those in n locations).
I saw a comment up-thread the some measures such as this may be considered over-kill. Last year around this time the price of Bitcoin went up 1000% in a month or so. If the price of Bitcoin spikes to something like $400,000 per coin, suddenly "use an anti-virus" is going to start looking seriously inadequate for protecting your 5mBTC (now worth $2000).
Bitcoin is game-changing in that it now makes previously impractical attacks profitable. I believe it is only a matter of time before a major software vendor pushes a wallet stealer in a software update. The only way to keep your Bitcoin savings safe is to keep them away from your network-connected machine in the first place.
