I would never try to convince anybody... I'm a big crypto enthusiast, but i still consider crypto a high risk investment... I wouldn't want to be responsible if they'd lose their funds.
On the other hand, if they'd made up their own mind and just asked me for assistance, i would gladly help them out

Same with my POV. I would never crossed the line and convince other people to invest into bitcoin, even if they are my close relatives or family members. Bitcoin has a lot of risks, and anyone who will only invest for its quick profits will never be good enough into bitcoin investment. They can always ask me how bitcoin works and how we can profit from it, its up to them if they will invest on it or not.
