Not quite as much fun as watching the price skyrocket while you meanwhile have your life savings in your wallet.dat.
...and more fun when your harddrive fails right after that
No, REAL FUN is realizing you have misplaced the USB stick with backups of your wallet.dat, GPG keys, SSH keys, and such important data.
Like left it on a table at DEFCON (hacking convention)
BTW I don't trust any media with unencrypted data, encrypted volumes should be in backups. Then it does not matter
