I may be seen as a newcomer and and a non-tech-savy person for asking this, but after serveral hours combing the internet, I now have to admit my defeat and ask the question instead of just finding the answer myself.
For long I have been wanting to invest in more "exotic" crypto currencies. What is the most secure way to do long-time investments in crypto currency?
I don't like the idea of having my currency lying at a broker, and ideally I would like to buy a currency, transfer it to a cold wallet, and then let the wallet and backups thereof sit offline until I believe it's time for selling the currency again.
Is this possible to do for anything else than BitCoins and Etherium?
