Following a good will Casascius apparently opened the pandora box. Now people are really believe that the sealing proves that the physical bitcoin is secure. But of course it is not. A producer of a physical note or a coin can copy and preserve the private key. This situation is so strange. I bet that if this hysteria wouldn't decline we will face a wave of fraud associated with a physical pseudosecured coins in a future.

It would be better if Casascius spend the same amount of effort populating the idea that only self printed paper wallets are secure. Every such cold storage obtained from a second party as a present, gift or a payment should be immediately transferred to the safer wallet because private key could be copied and preserved by a grantor. Tamper-evident seal in this case doesn't provide the needed level of security because the private key could be copied before the sealing was applied on a coin.

Shame on you Casascius Sad

Funny you say this and make that suggestion that I spend time promoting paper wallets, because I believe there is a decent possibility that nobody in the world has spent more time on promoting that very idea than me. I realize you're relatively new here, but why don't you use the forum search feature to search for all posts containing "paper wallet" ("wallets?") by username casascius.

Bitaddress.org does paper wallets in a large part because of my influence and suggestions and bounties.
The idea that paper wallets should be artistic and have an abstract resemblance to bank notes is something I introduced myself.
The ability to produce encrypted paper wallets that require zero trust from the manufacturer is also something I published on my own.
I don't fault you for not knowing any of this - everybody has to start out new at some point. So, welcome.

I really have made sure to point out that a physical bitcoin maker should not be trusted, that there should always be recourse in case of fraud. You are making a good point about an important principle. But just to be clear, and as others seem to have pointed out, your point is going to be more respectable if it doesn't purport to be putting people in their place with a dose of "shame" backed only by self-issued respect. Feel free to share your message - I agree it's important - I would just recommend you remember to use your manners at the same time.
