Hello guys,

Pretty nooby question here.
https://ledger.groovehq.com/knowledge_base/topics/which-altcoins-are-supported-by-the-nano-s-and-the-blue => Here is the list of altcoins/tokens that I can store in my Ledger Nano S. Which, I believe, is strongly accepted by the community as the safest way to store your crypto currencies safely.

But what if you want to hodl an altcoin that is not storable in your Nano Ledger S? (Let's imagine NEO and OMG for example)
I obviously understand that it's never a good idea to store any of my alt-coins in a marketplace like Bitrex for example.

Thanks in advance for making things a bit clearer to me. Hope my question make any sense.

Well you could try what I may/may not do  ::)

Download the crypto's wallet, and then verify the file hash (There really should be one provided, otherwise the devs dont know how to make a damn wallet) {hopefully it's a bitcoin-core clone or something along those lines}

Boot into a (securely installed - So verify the hash, of the ISO.) live Ubuntu USB and open the wallet offline (Unless there isn't a linux wallet, in which case you do a fresh install without internet), and then generate a private key for a receiving address.


Now you want to securely store this private key. I don't use the most secure method, but I find it gives me peace of mind. (I've lost way too many loaded wallets on my phone after doing a factory reset without backups)

I manually copy down each letter of the private key onto my web-connected PC, and after every couple of letters, I type a space and a random word. Then I continue typing a couple more letters, then another random word. Repeat. This prevents malware on your computer that detect strings that look like private keys, not realise that you're typing a private key (I hope). Then you encrypt this string of text using openssl or pgp, whatever you want. I just use my own PGP key.

I then take this encrypted block, and email it to myself. My email is then protected with 3fa.

It's not the most efficient, nor most secure, but that's what I currently use.

But then again, most malware/hackers only care for large cryptocurrencies or at worst, ERC-20 tokens (ew). I doubt they'll go for your random cryptos.
