Tails vs Bitkey vs Glacier Protocol vs other cold storage

[cryptoverted]

I've been doing some research into air-gapped cold storage methods and have found some options

• https://bitkey.io/
• https://glacierprotocol.org/
• https://tails.boum.org/index.en.html

Are there other well adopted methods with best in class security for cold storage, not only for bitcoin, but other cryptocurrencies as well (ethereum, zcash, etc.)? What do you prefer?

Creating a offline wallet on a live Linux cd. You would create the wallet just like you would on your personal computer but on a clean bootable live cd like Ubuntu offers. This option is good if you are not going to be accessing this wallet for a long period of time. Of course you can access it via the offline Ubuntu live cd if you wanted too. But, anything other than that could compromise it.

I'm not familiar with the options you have provided in your original message, except for tails. Tails is a very similar process to the one above.

I use Bitkey for my long-term storages. It's as easy as downloading and flashing the image in a flash drive, so the regular user won't have any problems with creating a safe environment without having to sacrifice their safety for convenience.

I imagine that you could download several tools for other altcoins - like MyEtherWallet - and use it in the same offline device along with the traditional Electrum wallet for BTC.
