Yes, I'm very late to the party but I'm going to have a go at this altcon malarkey. I've brought some Ethereum from Coinbase and I'm currently mining some minor coins via
Minor Gate which seems to be going rather well. My next concern is safely keeping my coins offline, so my question is ... is there such thing as an offline app or program that organises or stores wallets for various coins in one place or do I need to keep every alt coins separate?
