First of all, investing in cryptocurrency is very risky therefore I will not encourage them directly to invest in cryptocurrency but, I will introduce them about the advantages, profits, and also how to earn beside of its risky thing. I will also tell them about my experience in cryptocurrency. If they are interested and encouraged to invest in ICO, we should let them know the right ways to get in. We should also tell them what should do by explaining which cryptocurrency is good to invest or not. It is better to tell our friends or family about the cryptocurrency itself so that they can also earn money.
