As a newbie I started holding Bitcoins first, and then slowly got a few Altcoins. I think most people don’t know how crypto works, I don’t know how my phone works but I know who to use it. And the same are important with crypto, you need to know how to use it. If you invest into a coin you want to keep more than a few days or weeks, you don’t need to know how they coded that blockchain, but it will be good see what experts says about the blockchain, and also try to see how the blockchain works, by sending some coins from a wallet.
