GOAL:

Quickly and securely own your private keys in long term cold (offline) storage for the top 30 altcoins listed at coinmarketcap.com (instead of storing them on the exchanges), and extract each key/address string to store in your OWN way, rather than in numerous disparate wallets which each operate differently and may expect you to store and/or remember secondary files/passwords etc. A picture is worth a thousand words: https://i.imgur.com/8xiVMww.png

Background:

I've invested in so many altcoins now that I've kinda lost count, and it's the easiest thing in the world to keep them on the exchanges, especially if your time is limited. But as we've seen with Mount Gox and more recently BitGrail, exchanges can fail and lose your funds. It turns out hardware wallets and multi-coin wallet apps don't support many of the major crypto-currencies (for example, the Ledger Nano S only supports 12 out of 30, and Coinomi only 11/30), and are by no means guaranteed secure either. For me personally, I didn't want all my coins strewn across numerous apps and wallets – I'd rather have them all in one place.

Instructions:

After following the instructions for any coin, you can expect to create something similar, a giant list of your favourite coins, each with their own address and private key, stored in the way YOU want (I recommend storing the text file offline on at least two offline storage mediums (such as an airgapped computer or pen drive), and preferably encrypting it using a strong passphrase that you either write down on paper, and/or you memorize daily for at least a week (and once or twice a week for a few months thereafter). You may wish to use something like Keepass or 7zip for the encryption process.

Each coin has "Easy" and "Secure" instructions. There's no such thing as 100% secure, and you may wish to improvise further by setting up a Linux computer from scratch, but the "Secure" instructions should suffice for most people in most situations, especially if it means the alternative is not doing anything at all due to lack of time. As a further precaution, if you do send funds to such addresses, you may wish to only send a tiny amount first, and/or play around with a 'test' key/address (sending back and forth from/to an exchange) to see if everything works as expected.

For most links in the instructions, I have given REPUTABLE sources (shown in black below the links). These are usually the official sites, or sites that are endorsed by the applicable subreddit's moderator/spokesperson. Exceptions include very well known sites such as MyEtherWallet.com, WalletGenerator.net or apps/Javascript pages that are only required to confirm that an address corresponds with a given key created by a separate program from a reputable source (all done air-gapped for obvious reasons).

NB: Whenever any instruction says "offline", you should interpret that as: "Offline, on an air-gapped computer (such as an old unused laptop) which never sees an online connection", especially if you're following the Secure instructions rather than Easy ones.
