I recently saw the answer for this question which discusses how to sign a transaction from a cold wallet.
How does one setup a cold/hot wallet pair such as this?
The answer mentions that the hot wallet doesn't have a spend key, this seems like the most optimal setup for securing your coins.
Edit: While technically I can see how this question is a duplicate of others, I was intending to ask more for a tutorial on how to setup both a hot and cold wallet. Where as other questions aim for a more technical view of the mechanics of the technology.
