Which of the project are you referring to here, if it's bitcoin then it's a good idea for them to invest, but also consider that all fingers are not equal, some wish they could invest but don't have the ability to do so, to eat has become a difficult task for some people because of the situation they found themselves, to me i think a hungry man that has not eaten anything for the day will prefer eating first before thinking about having some savings for the future to invest on.
You have a point, just imagine how can your work well if you stomach is empty, you cant think well for sure that is why it is better to find food than thinking about earning money for the future, even myself those times that I've lost my job and dont have food to eat, the only thing on my mind is how to survive that day that we could eat then after ill think on where i should apply for work as i cant think well if I'm hungry.
I agree since the basic needs that we need to live everyday is the main goal of everyone. It is natural for others to prioritize their needs such as the food that they need rather than thinking of ways to grow their money. The reality is that the only ones who are financially stable in terms of providing their basic need are the ones who are really capable of what to invest since thinking what to eat is already settled and secured. I think it is always right to prioritize your needs since this would make you alive, but it really wont cause harm if you also try to think improving your life through investing if you can do so since it is also right for us to progress and really move forward to be better in the future.
