Why would I move cold coins was asked above? Cold comes in many flavors. My application was that the private keys were kept "cold" in the sense they were never exposed to an online connection. That definition works perfectly for me, and using this approach I could move coins every few days without a hassle if I needed/wanted to. The Electrum two computer approach is a true cold wallet. Now that definition might be a stretch for someone wanting to place coins in absolute isolation for a few years. The Electrum approach would still fully work, but those folks tend to want a paper wallet hidden in a vault. LOL!! As my operation and needs grew I wanted to be able to execute multiple transactions a day. Now the two computer Electrum approach became a chore. What to do? To remain "cold" with the keys as per my original definition of the term, I transitioned to hardware wallets and Electrum. Private keys are fully "cold" (within Trezors) but my transactions can be fully conducted on a mobile computer system while online. That is the way it "morphed" on my end.
i getcha. my setup is a lot simpler. most of my coins just stay cold and im willing to leave a portion of them hot.
