After you have clearly explained Bitcoin to them and the decision to invest must be left to them, don't force them to invest because they might blame us when they make mistakes in the investment they make, but if we explain it well and the decision to invest is theirs, of course we can't be blamed for explaining it to them well and most importantly, there is no profit that we can get easily, of course there is a process that must be gone through to be able to make a profit from investing in Bitcoin.
Even though you have provided good basic information about bitcoin, encourage them to do independent research or their own information about bitcoin before they invest, of course this will help them understand much better, by you encouraging them of course they will synchronize the information you provide is correct or not. 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.
Yes, you should really be telling them about into the risks involved when dealing up with cryptocurrencies. You cant really just that make yourself that makes money always and there's really that time that you would be able to lose money and the thing i dont really like is that when you do make out some recommendation to someone and if it turned out that their investment had some loses or negatives then they will be that starting out to blame you out and this is something that i dont really like and this is why i do only give out some advise into random people but for my friends then i might be having some reconsiderations on telling them but of course always consider out about the risks on which its really that important that you do really know about the risks factor because this isnt really just that talking about making money and thats something that you do put up into your mind. Explaining the opportunity about Bitcoin or crypto about making money then its good to share up these things but people do usually get blinded with their greed and thats why at the moment that you do explain up about making money then they would really be focusing into that and forgetting about the risks management on which this is something important but its commonly been neglected specially by newbies.
