good information, some of this is new to me and advanced. I will start googling. I have a spare laptop that I could dedicate to this.
Or use a hardware wallet (like
Trezor) not only it's safer, but the need for only one paper backup is a really nice thing (the same applies to
Electrum). Before Trezor I used to use Electrum on an off-line laptop for signing and had a watch-only wallet on-line (although transfering transactions back and forth via USB was a bit tiring ;c)).
What recourse is there when a trezor fails and the company is no more?
What recourse is there when I am dead and my family can't find where I put the trezor?
Maybe there are solutions but that's what I like about paper wallets. Keep the private key in a Safe Deposit Box. I can print them ahead of time and put them in the SDB ahead of time, they just have no value until I pay to the public address which I keep printed local (and signed with my name so I know it is one of my cold addresses)
I want to make sure it isn't too hard for family to recover the funds if a meteorite squishes my house tomorrow (which would destroy a trezor too).
