thank you @shorena
If you have a decent amount of BTC - don't rely on Electrum (software) Cold Storage. A software file is a software file. The best Cold Storage is with Trezor or Keep Key - which are Wallet independent.
i will look into trezon and similar wallets for sure but i don't like paying for a wallet that i can create for free.
I set my Trezor in dual mode, ready for the $5 attack - you know, the guy who threatens you to break your skull with a $5 wrench from Home Depot... They get my Trezor, I give them the PIN, but they only get my "change" wallet - where I keep less than $50 worth of BTC. They don't know it, but on the same device lies a wallet with thousand of $ of BTC with an encrypted passphrase... That is how secure Trezor is.
if someone threatens to break my skull i am going to give him the keys to my car and house
