Hi, I've put bitcoins in cold storage in the past and am considering buying Ether and some other currencies. I'm wondering if all/most cryptocurrencies require the same method as bitcoin to put them in cold/paper storage or if they differ much. You need a different wallet for most types of currencies, right? And is the process of putting the alt-coins in cold storage the same for all coins- or are there big differences? For example, do you put ripple and ether in cold storage in the same way that you'd put bitcoin in cold storage?
