Telling someone about Bitcoin takes a long time because there is so much to learn. So if someone makes a wrong decision and does something wrong, they can blame me for it, so I'm also very afraid to influence anyone about Bitcoin. However, if someone asks me something out of interest, I try to teach them with my best. But I tried to convince my family members about Bitcoin but they are old age people so I couldn't convince them much.
Yeah I do the same thing, I never approach someone and tell them about Bitcoin or cryptocurrencies or try to persuade them to make investments in them because I know that in case their investments don't work out and they lose money instead of getting profits, I'm the one they are going to blame because it was me who approached them and made them interested in them and they didn't know about them beforehand. Apart from this point, you should never let anyone know that you have money invested in cryptocurrencies or have any involvement in it because that can be a security concern for you.
When it comes to family, one should at least let them know that there is something like this where they can make investments and if the market goes up, they can make profit from it, however it is necessary to let them know about the risks involved as well because despite being family members, they can also blame you if they lose money.
