If I've lost my wallet, but know my bitcoin receiving address, can I get my bitcoins back? Although I do have a backed up wallet file, I seem to also have a second bitcoin receiving address, which doesn't seem to correspond to it. Is there a way to recover any coins associated with that receiving address, or are the coins lost forever?
You can't get your bitcoins with just the receiving address (if that could be done, they could easily be stolen), so your only chances of retrieving them are:


If they're stored in the wallet file you have backed up, then you can use that
Somehow recovering the original wallet file, which is a data recovery exercise. This might be possible in the case of a failure or deletion of a hard disk, or a deletion from an SD card/memory stick
