I need to see which addresses contained coins 1 year ago at date x.
all coins from my wallet were moved already to a different address
my wallet balance is 0 now
1) go to your console and get the list of all your addresses.
listaddresses()
2) go here:
http://www.findmycoins.ninja/ and paste the list here and separate them with a new line and remove any extra symbol that it might have (like " or ,) and click search
3) now from the results choose the ones that contain some fork_coin and copy the single address.
4) go back to electrum and get the private key of that address
getprivatekeys('Your_Address_here')
enter your password if you have one and you will see your private key.
5) copy it and use it in any fork_coin wallet that you want and claim your reward.
it is best not to use this wallet anymore. move to a NEW wallet (not just a new address from the same wallet) create a new seed.
