Yes, of course you can. The only thing that can happen is wallet.dat getting corrupt, and that's why you need to have a few backups instead of just one. Just install a wallet to your PC whenever you want (a year later as you say) and paste your wallet.dat to it's original place and you will get all your coins. Oh, and backup your password aswell, it's even easier to forget it than lose your wallet.dat :p
Ok, great thank you @Denmor, just so I have this 100% straight tell me if there is a flaw here, lets say I put $100 in Feather coin, then I encrypt the wallet (save the password somewhere safe I got that worked out already over the years) then make 10 copies verify a few to make sure they are not corrupt put 10 in 10 places, zip drive, cloud storage, my website etc...
Come back in a year, download the Feather coin wallet on a brand get laptop, grab my Feather.dat from dropbox rename it Wallet.dat replace the current wallet.dat and wolla my $100 in Feather coin are there?
I'm assuming no one can break the encryption other then that is this reasonably safe to do? I would just need 1 of the 10 Feather.dat files to survive in order to retrieve the money right?
