What is the difference between making a "backup" of my Swing wallet and Exporting my private keys? Do I need to do both to backup my wallet? I would assume I should store these on a USB in a safe place
I haven't used Swing wallet.
Taking bitbill as an example , you only need to "backup " well your wallet.
In genaral , the private key corresponds to managing an address. We don't need to Exporting our private keys if there is no other necessity.
We can recover our wallet with mnemonic words.
BTW, BitBill wallet supports ZEN .(Android soon )
