If you're just storing Bitcoin & Litecoin for long term then you should just create two paper wallets, one for Bitcoin and one for Litecoin. You can create them while disconnected from the internet and then you just send the coins to the address on the wallet and when you want to spend them you import the private key into Bitcoin-QT or Litecoin-QT. Also some online wallets allow you to import private keys. You can create paper wallets at the following websites, *CLEARNET WARNING* www.BitAddress.org (Bitcoin Wallet) www.LiteAddress.org (Litecoin Wallet) Remember before you hit "Generate" on the website disconnected from the internet to make the wallet offline. This is then considered cold storage.
