No because floppies are notoriously unreliable. You just got lucky with those particular disks.
Maybe that was the case, but all the IBM and Sony ones are working lol. And I have found an even older floppy (the ones that folded), I would like to try this one out but I don't have a reader for big floppy disks anymore, but im sure someone already made one that can connect to usb
Are floppy disks safe to store wallets?
No.There are way better alternatives nowadays. I'd consider CD, DVD, M-Disc, Cloud storage. Just make sure your wallet is encrypted with a strong password and with quantum proof encryption.
And always name your wallet files randomly, naming as "My Millionaire Bitcoin Wallet" is definitely not a good idea and will just encourage brute force attacks and attempts. Naming it as "travel_71nYNujPnL" would work otherwise.
Even binary data printed in sheets of paper and buried somewhere in this planet would be safer than a floppy.
Yes, I have backups everywhere and they are all encrypted. What do you consider "quantum proof encryption" to be tho??
