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.
Overall, what you do is correct, it is true that crypto has risks, but there is no denying that the opportunity of the crypto industry is also huge, so there is nothing wrong with you sharing the opportunity with everyone, especially your loved one. Not everyone succeeds in investing in cryptocurrencies, and what you need to do is explain all the risks associated with this industry rather than the returns. Let them be fully aware of the consequences they may receive and so they can make their own decisions.
I talk about crypto since 2015, many around me didn't know anything about crypto 8 years ago. I never felt uncomfortable when I was trying to bring the crypto world closer to them (to those who were interested to listen). Even now I try to explain to them about the crypto itself and all the opportunities, and one of them is definitely trading. I always try to point out all the risks associated with crypto and all crypto stuff around us (trading, staking, gambling, mining, etc), and I repeat many times they shouldn't invest more than they can afford to lose if they decide to give it a try. And of course, if they stuck at some point I will help in any way I can.
