Well that's a good idea. The only problem I see with your suggestion would be the slowness that I get when I run a Linux Operating System in a stick, it's a real drag. I'd rather quickly plug a standard stick into my full-size Linux, quickly transfer coins, unplug and begone. My Linux computer has quite strong defences (which is why I don't put my crypto activities in windows).

And I don't really have a cavern of space because wallets for Litecoin and Ethereum are going in there too. But for sure I like your idea of encrypting the stick carrying the encrypted wallets. [Maybe I should think about a plug-in SSD drive]. Well thanks for the ideas.

Many thanks. You clarified for me. I just moved the default_wallet and set up the command

Hi

I have Electrum installed in Linux, using all the defaults as is.
But I want a simple cold-ish wallet setup where the key files can be shut off at will.
The key files, including wallet, are supposed to be installed at /home/fred/.electrum.
I have a 26Gb USB stick that I have changed to have ext4 file system, to match the ext4 in /home
I mount the USB stick in /mnt/sdc1 and chown it correctly as both owner and user.
I move .electrum to the USB (ext4) stick.
I put a soft link where .electrum should be, with target to where .electrum is now, in the stick.
When I run the command "electrum" the QT interface pops up and it seems to work fine.
 
When I finish a transaction I can unmount the stick and put it away, in cold storage.
Have I missed anything? Have I done anything to put in jeopardy my coins?

Thanks for advice
Fred
