Introducing Bitcoin is good but not to the point that we have to urge people to do that. We let them decide rather than take the blame for ever they lose. It is wrong to take responsibility for others, we are making them reliant and weak. Instead of pushing OP to his friend to invest in crypto, it is better to take time to think first because it is difficult for someone to engage in risky investments with an empty mind, it only worsens the situation and even compromises their friendships.
Introducing someone to Bitcoin is of course very good because Bitcoin has experienced very good development since you appeared, but we have to be able to explain it in detail so that they don't misunderstand Bitcoin and if they have the desire to try investing, of course. we have to be able to guide them until they really succeed, but if they don't want to try of course we shouldn't force them because this will be very risky when they fail to invest of course they will blame it. we are the ones forcing them to invest and this will make our relationship bad because they fail in trying what we force them to do and it will be better after we explain it well to them, we have to ask them first if they want to try it like it or not and if they don't want it so we shouldn't force it.
