Thanks

This tool lets your generate PDF paperwallet for arbitrary altcoins
using QR-Codes for fast access to the address and the private key.




Howto Create PaperWallet

• Store address and privkey in csv file
     You may select one of three options to generate you wallet.csv file with
     private keys in it. Read the header of the files to adjust the settings to
     your needs.
  • 1_createEmptyPaperWallets**:
            to create new empty wallets using vanitygen
            press ***Ctrl+C*** when You have enough
  • 1_createNewWalletsAndMoveCoins**:
            to create new wallets using the bitcoin daemons and move coins accoring to the settings in that file
       
  • 1_importExistingWallets**:
            load existing wallets from deamons using 'listaddressgroupings'
       
• Uncomment _ONE_ note layout input line in 'paperWallet.tex' (line 41-48)

A nice guide :) Good work!

Personally, redundant-redundant backups of my wallets is enough security for me but there's no excuse for not having an old fashioned, paper copy.
