The best Bitcoin cold storage?

[Inotanewbie]

#3 paper wallet stored in safety deposit box
#2 crypto cards
#1 Brain Wallet*

*But not if you're a moron

#2 is probably a bad idea, as it would likely mean that you are trusting your private keys to a 3rd party.

#3 is most likely bad because the human brain is very bad at being random and will likely pick something that can be guessed by the many botnets that are checking possible brain wallet combinations.

I beg to differ regarding Brain Wallets. Brain Wallets can be the most powerful wallets if you take care to use a protocol like Diceware to generate your passphrase and then use the simple method to memorize it as described in the link below.

The advantage of brain wallets is the fact that you can lose everything (backups included) and you can still regenerate your wallets. If you are worried about forgetting your passphrase, split the passphrase into multiple pieces stored in multiple different locations and then add redundancy if so desired.

Of course, my favorite tool to create these is my CoinKee™ http://coinkee.com  

BTW, crypto cards are fine if you use a strong passphrase to encrypt your private key via BIP38 before sending it to them for manufacture.

Just insure it and put it in the local bank safe box...

The service https://BitArmored.com is extremely high-security cold storage with a Live/Hot Wallet for instant transfers and option to store large amounts offline in cold storage.  You can even request an encrypted flash drive containing an electrum wallet which is what we use for each client's funds.

I've heard good things about bitplastic, which is also owned by you correct? I would trust it if I had a lot of bitcoin, but I dont...

I'm building what I think will be if not one of the best cold-storage devices certainly the most attractive. :-)

I think best method 3d printed wallet. Ultimaker 2 can make really good 3d printed QR code.

[ManeBjorn]

Wow these look cool.
How close are you and do you need funding?

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!

Why not store your private key in an ATP microSD card and store it in your container?

Electronic storage is not intended for long term: electromagnetic fields can wipe out your data, and due to memory cells structure the data can fade if not refreshed in 4-5 years

Glad to know. I guess the people who uses the usb which was installed with linux system where their bitcoins were stored aren't also safe.

How do you  store them in Airtight Pill Fob by the way? are you going to write down your btc address and password in a paper store in that Pill Fob ?

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. :-)

I am using #3, as I believe that paper wallets is the most safe option. Right now no computer program is capable of cracking a 22-character long pass phrase (that doesn't mean that in future it might still be so).

I think I can see what you are doing ... it's cool! Keep the rabbit in your hat, for now.

Go ahead and do a web search on bitarmored or check http://antilyze.com

Moriarty steals bitcoin = FACT

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.

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!

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...

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