If you have introduced those who are interested in Bitcoin to Bitcoin given them the basic information to start with, then I will say you have done your part it’s now left with them to make further inquiries if they finally decide to invest maybe they can ask you how to which is from their own person decision and not you convincing them to invest.
That is the best thing to do, if you help someone with correct details on Bitcoin, allow them to carry out their own research to determine whether Bitcoin is a real investment and worth trying. However, if you continue providing the information without allowing them to learn the rest on their own, some individuals will believe you are trying to pressure them to invest their money in the wrong place. Just do your part and let them decide what to do next.
And also remind them that investment is a personal responsibility, not the responsibility of the information provider, that way we won't be blamed in the future. And also remind them that bitcoin will provide long-term benefits.
Even if we do not expect to lose money in Bitcoin if we invest for the long term, it is important to inform anyone we want to introduce to Bitcoin that it has a lot of risks and that they may lose money as well because some people want to invest in Bitcoin to make quick money since people have been saying good things about it, but they need to have patience and invest for a long time to enjoy the benefits.
