for me there are three reasons why they do not want to invest in crypto
1. they have not known crypto
2. they are not interested
3. they are afraid to invest after losses
I agree into this they are afraid to lose because there are some fake news that are saying that this is just a scam that is their mindset. Because I asked some people why they do not wanted to invest all of their answers are they are afraid because they do not know this fully and this is a new technology for them which is not that trusted. They said that they are not used to this kind of stuff. They much more contented into something the is used to be rather than trying new.
