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
Yes, you are correct, most of them doesnt know what crypto is all about, they don't want to waste their money because they just think that investing in crypto is not true and they wont get any benefits from it but as we all know and have tried it, we are sure that investment in crypto is worth it.
