you can explain how good btc to them, how much profit they will get, only with their computer capital can produce a little btc and if they seriously do it then they produce big btc by following signature campaign. not at risk
For me, once I share something and I felt that their not interested, I'm not going to force them or convinced them to believe of what I'm saying besides I have nothing to loss, and their just throwing a good a opportunity. Unless family member is involved, because I know in my self that Bitcoin is real, so I won't stop convincing them just to try working in bitcoin, cause I want them to have a good life someday.
