It's generally wise not to do anything confidential when anyone or any device can see you.
if you dont trust your own family in your own home. maybe you should get a divorce and get your kids sent away to be adopted.(joke)
My kids are young, I don't want them around when handling sensitive stuff because they're distracting.
seems some are a little too paranoid in their own homes.
With 5 listening devices equipped with cameras in the house, I don't think you can be too paranoid.
put a hammer to your PC and printer to stop family from checking your document history later
A live Linux DVD and dumb printer solve all this.
and for the rest of your life, not keep the paperwallet at home.. because you dont trust family to not find it a day, week, month later laying around the house.
How is this different when storing 24 seed words to a hardware wallet?
the only real advice, without the paranoid 'over-fearing' scare tactics is:
to not do it on someone elses device, EG in a public library.
to not make a single paper wallet with significant amounts on it
You forgot one:
Don't use Windows.
the real world fear is not your coins being stolen. but your access to your device/wallet being taken where the coins end up 'burned' via lost keys
That's a perfect use case for paper wallets, they're much easier to copy than hardware.
