How to properly learn crypto

I've been in the crypto space for awhile now (2+ years), although now my cousin is asking me advice on how to invest. I don't want to flatout tell him my portfolio and leave it as that, then rather I would teach him. I personally Look at a cryptos whitepapers, tokenomics, usecases, community etc. Although I don't know the best way of telling and teaching this information. I was hoping you guys could share some wisdom toward the steps he should take toward investing and any other insight. Cheers guys
