I have now been using trezor as cold storage. I like how it is almost like a hybrid wallet, where you don't have to sweep the entire thing when you want to spend.

The one downside is that you have to rely on their API (I think). The backend of the website was down the other night, so none of us had access to our coins in the meantime (unless you wanted to use the recovery seed on a different wallet)

I personally do not trust trezor. You should have 100% access to your private key at any time. If their website goes down then you need to have a way to recover the private keys

Well, use your backup! :-P
It's standard-conforming, following the BIP0038 scheme.
Either put it into another Trezor, or in your case, any other BIP0038 client.

We seem to have quite a few topics created about "cold storage" lately - anyway for anyone interested in 100% "air-gapped" security using an Live OS (created using SUSE Studio) there is this: https://susestudio.com/a/kp8B3G/ciyam-safe (it combines an offline bitcoind with GPG, scrypt and does all comms between online and offline computers via QR codes).

I would not trust trezor because their hardware is very new and untested. They do have "open source" software, however you do not have any real way of verifying that the software on your trezor is the software on github. You also have a huge amount of risk regarding the shippment as you do not have any real way to verify that the shipment was actually sent by trezor and was not intercepted

Touchdown

I currently use an always offline Raspberry Pi with Electrum. Signing transactions is easy enough and hiding the 12 word mnemonic code in random files and emails means I can rebuild the wallet at any time, anywhere in the world, should I need to.

Mycelium is great for spending from cold storage wallets too (change is returned to the same address).

In light of this:

CoinKee is transitioning to CoinPro (no USB - LiveCD only):

http://coinpro.me

This is a good move considering the recent USB firmware hack that came to light. I can't find the link at the moment, but suffice it to say I didn't know USB firmware could do that shit. I hate discs altogether, but it seems that lo-tek old school is proving more and more secure every day.

Only if you trust your wife. Otherwise, hide it inside your own body.

Those look really cool. Kind of how I would imagine pills in heaven...lol. I have been thinking about getting one of these. I like to spread things out in multiple places so it isn't all in one spot. Andreas was talking about how he carries around a FOB with an operating system and wallet on it...

Sure looks funky!
After searching through your site way too long, I found the description page.
That page doesn't really explain what this *is*!

What is it? What material is outside? What's inside? Seed, key, wallet? Encrypted? BIP0038?
In case that stuff is written on that page, sorry, I only skipped through it after reading half of it - it's too much text.

I don't mean to offend you, it's meant as constructive criticism!

I'll make a better site in september to better explain it. I was actually thinking to do a little video to help explain. Basically it's an NFC device sealed inside a device that can't be counterfeited nor broken open and resealed. It's one time use only and serves as like a secure password container where you don't need to trust me the manufacturer to safely use.

I've bee showing a lot of people in person and testing different ways of explaining how it works. Once I hit on the simplest way to explain it I'll let you know! But generally september I'll do better at explaining that. :-)

That sounds cool!
Well, as long as that stuff is long-term reliable.
Remember how they told us "CDs last 100 years" or the like? I had problems reading in my CD-Rs after less than 10 years..
Flash cells are worse. Now I don't know a lot about NFC chips, but would always feel safer having at least one optically-readable backup. And that means at least a QR-code, and preferrably something with letters and numbers.

Actually I had that idea as a child: some secret message enclosed into a glass tube, where you couldn't read it without breaking it open first! So, yay for nice flashy coldwallet!

I like this a lot, I would be very interested in buying one!! I think il get one of these and dig a 2 ft hole in the garden place in in the hole and put a rock over directly where it is just in-case of a house fire or robbery or anything.
