I don't want a situation whereby someone will say that I scammed him if there is a sudden dip in the crypto industry, so I just told him to open a binance account and verify it, after then, he should get back to me so I can send him the hard copy of the crypto course I bought.
Uptil now I still feel uncomfortable about it, I don't know if am wrong or right for opening up, even though I told him of the risk involved.
Common worries of people who became the reason why a person engage himself in crypto. I understand you well because i'm once in such situation wherein I was held responsible of someone I just helped. But I don't see anything wrong on what you did since you already told him the risk yet he's still interested.
What you can do is help him understand more about trading. Remind him that it's not easy and gaining is not guaranteed. So he will keep in mind that even trading works for you or for other traders who are earning a decent, it's still different for every traders since it depends how knowledgeable and good you are when you trade.
