Topic: DIY,Bitcoin cold wallet USB stick creation step by step guide (Read 5604 times)
right ... that's not too complicated for people ...
Great guide, will definitely use this in the future. I should really have more backups of my wallets, and I should have a cold wallet as well (paper or something). I don't even trust printers, man. Especially those network-connected ones.
I am not that much of a fan of USB, and it can get affected.
So, I write a simple application to transfer data through air gap by QR code movies:flipqr : https://bitcointalksearch.org/topic/flipqr-transfer-long-text-or-small-file-over-air-gap-978033

nice guide but a hardware-wallet is better for a newbie i think

While I do think this was a very well written tutorial, Elwar has a point in regards to usb security. I saved a copy of your pdf for future reference however.

Will try this. 
But why Electrum? Isn't Armory generally better suited for cold wallets?

thanks a lot for creating this walk-through it was so useful
the only risks for using this way are: forgetting your passwords and damaging USB stick physically nothing else comes to my mind
and for preventing these two you can write your seed and/or passwords on a piece of paper and keep it safe
The viruses can be wrote on USB device firmware.thanks a lot for creating this walk-through it was so useful
I do not think that USB stick is safe wallet - there can be a lot of problems. For example, there are viruses, that use USB stick. And if you use one Linux OS - you can use only that one Linux OS, so you can not use USB stick in other machines with different OS then.
i have never head of virus on linux! there is none.the only risks for using this way are: forgetting your passwords and damaging USB stick physically nothing else comes to my mind
and for preventing these two you can write your seed and/or passwords on a piece of paper and keep it safe
So don't use any untrusted USB devices (include keyboard,mouse, charger) on wallet PC or mobile.
and don't plug the USB stick into untrusted PC.
Don't flaunt your funds.

Make sure you also keep paper wallet or other forms of backup, i feel sorry for anyone who only keeps a backup on a USB key. USB keys are unstable and TOTALLY UNSUITABLE for keeping important data long term
many will discover this the hard way...
Yes , we need to write down the 12 words Electrm wallet seed on the paper and keep it in safe place.many will discover this the hard way...

For novice, the pdf document with screenshots is more easier to understand,

also, why did you boot Ubutu from USB? isn't it enough to boot it from the Ubuntu CD?
and about the partition that you created on USB. was it for booting Ubuntu or keeping the installed wallet or both?
i meant can't you just create the partition with Ubonto and keep ONLY the wallet there?
sorry if my questions was newbish
2, Create 2 partition is just a junior protection. Windows OS can't find the 2nd partition.
Both Ubuntu and wallet keeps in the 2nd partition.
Yes, if you like, you can skip the usb disk partition steps.

I think you should add this truecrypt encryption
If you use dedicated PC for cold storage, full filesystem encryption is good.
the performance of full filesystem encryption on USB disk is not well.
Yes.
To avoid the BAD-USB firmware risk, don't plug the USB stick into untrusted PC.
and don't connect untrusted USB devices (include keyboard,mouse) to your offline wallet computer.

Do not rely too much on a USB being secure.

Also backup or clone.
