For me, memorising the private key was the only way to go.

The safest place for you will depend on your circumstances.


Or maybe even better, use steganography. Take some random document (e.g. a mailshot). Use some part of it as your brain wallet passcode (maybe the third paragraph). Put the document in a bank vault. Then all you have to remember is "third paragraph".

On an offline computer, create a split wallet 2 out of 3.
Keep one of the fragments at home for reference, and store the other two in separate bank vaults (here in Germany those cost less than 50 EUR per year).
You probably won't get much safer than that.

The safest way to store your wallet i think is buy a server with a raid array for obtein redundancy from the disks and power redundant power supply look like this if you have more than 1 server so cool, you are having a cluster.

CIYAM safe  - offline tx's using QR codes for comms


so there is no need to plug any USB device etc. So the hole process of signing transactions etc. works with QR codes ... see ref post...

https://bitcointalksearch.org/topic/ann-ciyam-safe-offline-txs-using-qr-codes-for-comms-134833


Quote
Another milestone towards CIYAM Open's 2013 mission has been achieved with the publication of the CIYAM Safe LiveOS on SUSE Studio: http://susestudio.com/a/kp8B3G/ciyam-safe

Using the distro as the LiveOS and after installing ZBar on your online computer you can create addresses and sign transactions in a manner that does not require USB (other than the live distro itself) as long as both your online and offline computers have webcams.

All source code is included - several various scripts and utilities are included from https://github.com/ciyam/safe and a slightly modified (just command line args not algo) version of "scrypt" from https://github.com/ciyam/scrypt.

If anyone would like to help test this it would be greatly appreciated (please consider it to be a "beta" at this stage and only test with very small amounts of BTC).

It should be noted that this is *not* trying to be an offline "wallet" in the same vein as Armory (although I guess it could be used for that purpose) and is not suitable for the technically non-savvy (you need to construct raw tx's) or for performing large numbers of tx's quickly. It's a bit more of a "nuts and bolts" type solution that was put together for the purpose of being able to create "paranoid" levels of security (as CIYAM Open intends to make sure its donations do not go anywhere apart from where they are meant to).

It has been tested with real transactions and testing also included re-installing the LiveOS (i.e. as if you'd lost it). The documentation is serviceable but far from "great" and the whole package could certainly be improved with some polish (if others are interested in using this and would be prepared to donate some funds towards adding more functionality then I will consider opening a project for it on CIYAM Open for it).

Of course others are welcome to copy this (or add QR comms to their own offline wallet projects).

Encrypt your wallet, then burn your wallet into a CDROM, finally destroy your PC disk wallet completely.

And hold your CDROM carefully.

You can get hacked by Alzheimer's. Make sure to save paper backups still.

One must weigh the probability of forgetting vital data against the probability of having your paper backup read by someone that knows what it means.

You still have to remember where do you keep the backups Grin

Oh, you are about an encrypted wallet. It's correct.

The only keylogger possible on a not rooted phone is keyboard, so it is pretty safe to use default keyboard. And it is much easier to have offline small android than an offline PC/MAC.

I still say that encrypted software wallet like Multibit is better than paper wallet.  Of course back it up...on the cloud, on multiple USB sticks or microSD cards, etc.  As long as it is encrypted with something like PGP or True Crypt, you can name the container anythign you want and no one would know it's bitcoin and even if they found out, they couldn't do much because PGP has not been cracked.

Paper wallet can be found and seized and if it's not encrypted, then there go your BTC.

But a keylogger or malware can steal your password when you decrypt it.

This is what I did, too. But it is a bit more technical than the original steps 1. to 4. Like the OP I am not a computer wiz. The additional step took me a couple of hours to sort out. You have to find out what Ubuntu is and what version to get,  download it, get the computer to boot off it, work out how to run bitaddress.org via Ubuntu, and finally get the printer to work with Ubuntu. The last step was particularly frustrating (!!!). Definitely safer though if the OP has time and is not computer-phobic.

It can be done more easily and safer - take paper wallet for android and write down a generated key. Just make sure that device is not rooted to prevent external access to app memory. Oh, and the minikey could be tattooed faster and more easily than a QR ;-)

1. save https://bitaddress.org/ to a usb stick
2. go to a secure workstation and disconnect it from internet
3. load up the saved webpage and print off a few paper wallets
4. stash your bitcoins in those paper wallets

this is a good idea ^^

+1, That's what I do.. plus on the usb stick I put a live version of Ubuntu

Bitcoin Armory running on an offline computer, with a couple copies of backups printed and stashed in safe places. You can create a new bitcoin address for every new deposit you receive (thus not showing that you have a lot of coins), and you can still safely spend them when you need to without any exposure to hackers.
