A thought experiment i wanted to know.
I have saved it in a disc (was inspired by satoshi who stated it that he has saved it and buried it)
memorised and saved in hdd in air gapped though!
From a disc, you mean compact disk? Cmon now a days no one uses a compact disk.
But yes i know everyone has their own choices.
I have stored my keys by writing it down in a piece of paper, actually i made 3 copies and kept it separately for emergencies.
Alternatively i have another wallet which has low amount of coins, and it’s private keys i have kept in Gmail account.(it’s not safe and not recommended).
So i can advise the OP at last that, do write the keys in a paper and keep it close to yourself, days are growing and soon cds will extinct. So watch your keys before it gets lost.
