One option is to use myetherwallet for your ERC20 coins. You can use the option of 1 wallet for each coin, with the file saved on a flash drive and the white paper printed and stored. Or use 2-5 different wallets to split your coins up, just in case one the wallets gets hacked, you don't lose them all. Any option you use, save the file on a flash drive and print out the white paper for max security......Fraud sucks
