Is not good for us to force people to invest in Bitcoin because they will fail in it, what we are suppose to do is to educate people about Bitcoin and how Bitcoin works then allow them to make decision to choose to invest or not, some set of people who where into bitcoin investment and later stopped investing is because they where forced into Bitcoin investment and some people where also given false information and that was why they joined Bitcoin investment I know of someone who thought Bitcoin would give him profit in less than 2 weeks of his investment and this was because he was given false information some newbies really don't understand how Bitcoin investment works some set of people thinks that Bitcoin investment is like Ponzi scheme where you can just investment and get huge amount of profit in a week later, and this false informations given to people has really given Bitcoin bad image, the best thing to do is to give people the right information about Bitcoin and also tell them to do some research by there self and let them go through the history of Bitcoin growth if they decide to invest after everything then they will be determine to succeed.
Since, Bitcoin is risky, no one should be forced to invest in risky sectors. However, Bitcoin has good prospects in the future, so it is not a bad decision to give an idea about Bitcoin to those who are not aware of Bitcoin. Now if you force someone to invest, he will blame you if he suffers a loss in the investment. You should, give them idea about DCA, talk about investing long term, give idea about good wallet, you tell them about risk. I gave some of my friends ideas about Bitcoin, but never asked anyone to invest, they decided to invest on their own. Some of my friends plan to hold for 8-10 years. But I never forced any of my friends to invest, they invested on their own risk.
This is the basic principle of investment, and if you give someone an idea about investment, never involve yourself in it. Ensuring your own safety is very important, someone will invest with excessive expectations from your words, but if they do not get the results as expected, they will blame you. And it is very natural to blame them like this. So if you want to explain investment to someone, you have to explain it in such a way that he himself takes a long-term investment decision. Just educate him about investment, if he is really interested in investing then common sense will be enough for him.
