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
Um? I think you don't even need Electrum to do this.Just copy the address you want to know how many coins where deposited to it and paste it in a blockchain explorer to find out the date of deposits and the amounts.
A common blockchain explorer
