I have been saving ETN now on a paper wallet. What you do is create a Paper PDF wallet and then save it in a memory stick.
Cut out the Public Wallet box and save it where you can get at it.
You can use a paper wallet like a bank account as when you pay to the Public Wallet box the amounts Add up! Your Paper Wallet will be safe on the Memory Stick and you can safely have the Public Wallet Box anywhere while you keep adding to it even when your internet is on so it will look like below.
I have also copy and pasted the actual numerical code too and you only need one Paper PDF Wallet.
Any thoughts on this or how to improve it are welcome.
