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.
