If and only if they are interested! We all knew that even if they believe us that crypto is not a scam, we cannot totally erase how how much risk is associated by investing on cryptos. And I don't want to take the blame if ever other people lost their profit or investment. So probably no way.
I agree, I can give advice, but only if people themselves are interested in crypto currencies. Because the crypto currency market is unpredictable, today it can grow by 100%, and tomorrow it will fall by 200%. I always warn people about the possibility of losing money.
Just like any investment, if you're telling people to invest in crypto you should advice them to take their own risk so they don't curse you when they end up losing money. Educate them on the benefit of crypto without asking them to invest in it, they should invest on their own if they feel comfortable.
