Incorrect, someone don't want to teach his friends because he worried if his friends will blame him after his friends invest in cryptocurrency. Or his friend will ask money because they know you're making a lot profit from the crypto you told to them before.
Yeah I agree, getting your loved ones to invest in cryptos can be risky. You always think you know people, until one day it's about big money. People change when the money runs out, or when things goes wrong.
I invested in mining equipment with some people I knew (not closed friends), but from that moment on, I considered them as associates and not as friends. I think you always have to keep a social distance from people you do business with, and you can't do that with friends. That's why I don't talk about money with my friends.
Actually teach friends to invest in crypto will make you earn more because the demand of the coin is increase (in case he buy it).
Yeah, on a very small scale, unless your friends are billionaires and ready to invest tons of money. And in general, very wealthy people doesn't need advices from friends to make more money
