Cold storage for crypto wallets

Since I am trying to be very careful when storing my crypto assets, I am here describing (possibly very strange) way of storing my private keys. I haven’t see this anywhere, so please comment if you think I am doing something wrong.It is done as following:download the programs you need to generate keys for specific crypto coin (BTC, ETH, LTC,…) and copy them to USB.take another USB and make bootable USB with Ubuntu (you can use any other OS, but I prefer some light Linux)disconnect from internetkeep in mind that you are off the internet (and off any other network for the complete time of this process)turn off the computerunplug the hard disc(s) from the computerPlug in the bootable (Linux) USBTurn on the computer, which will now start booting from the USB (or you will have to adjust boot sequence)Plug in other USB and copy all the programs you need for wallet (key) generationUnplug the USB with wallet programsuse the programs and generate all necessary keysconnect printer and print paper wallets (key)copy keys on some other (third) USB device if you want (you can also immediately encrypt them using fx. VeraCrypt)Turn off the computerDisconnect all USB drivesTurn on computer and start BIOS. Perform memory test to purge all working memory. This will ensure that there will be no trace to the generated keys on the computer.

It is done as following:

  • download the programs you need to generate keys for specific crypto coin (BTC, ETH, LTC,…) and copy them to USB.

  • take another USB and make bootable USB with Ubuntu (you can use any other OS, but I prefer some light Linux)

  • disconnect from internet

  • keep in mind that you are off the internet (and off any other network for the complete time of this process)

  • turn off the computer

  • unplug the hard disc(s) from the computer

  • Plug in the bootable (Linux) USB

  • Turn on the computer, which will now start booting from the USB (or you will have to adjust boot sequence)

  • Plug in other USB and copy all the programs you need for wallet (key) generation

  • Unplug the USB with wallet programs

  • use the programs and generate all necessary keys

  • connect printer and print paper wallets (key)

  • copy keys on some other (third) USB device if you want (you can also immediately encrypt them using fx. VeraCrypt)

  • Turn off the computer

  • Disconnect all USB drives

  • Turn on computer and start BIOS. Perform memory test to purge all working memory. This will ensure that there will be no trace to the generated keys on the computer. This is also maybe a hardcore step which might be unnecessary.

  • Turn off the computer

  • Plug in the hard disc(s) back to the computer

  • Connect back to the internet
