1st thing you do after funding a wallet - dumpprivkey! Print it out, keep it safe, tattoo it onto the tonsils of your pet assault crocodile, recover your balance easily even if all your wallet.dat backups get eaten by undead alien tentacle-horrors!
I am NOT retarted !
I have 4 backups and am double german paranoid on this !
I had a spelling mistake in the passphrase !
believe that ! Yes, think about it,
as you can not see what you actually type these things ( i guess) can happen !!
so tattoo it on your forehead,
but if you misspell it in the beginning that tattoo will not help you ether !
