How is paper wallet with private key not a "Bitcoin Storage method". You store BTC on a address you have private key to. Once you need it you can put private key into many different wallets depending on what's your favorite.
Yes that is what I meant. You said that a paper storage method is a method, but not in my list, because a signed data has to access an online PC to broadcast the transaction, which will happen in 1-9 ways.
So a paper wallet is irrelevant in this discussion, as I`m talking about PC security. Plus a paper wallet is worse secure than a hardware wallet, because both can be extorted from a person but a harware wallet atleast has access to the PC and its more practical.
The whole point of a paper wallet is that it keeps your private key (and BTC address) offline. So it is stored on a piece of paper. Your thread is about storage... not transmission. And I'm talking storage in a safty deposit box or similar, not in a desk like one mentioned above.
I think leaving a big some on a PC is a bad idea for the most part. And even military grade can have someone take BTC there is a level of trust at this level that a "bad guy" can take advantage of just look at silk road where agents took BTC - http://www.coindesk.com/former-silk-road-dea-agent-pleads-guilty-to-bitcoin-theft/ So even military computers are not perfect as long as a human is part of equation. According to your list this cannot happen as these DEA agents no doubt were military grade hardware and site.... but it did. No way of storage has zero risk.
Your logic if flawed in my view.
