people doesnt want to invest in crypto maybe because they are not intersted on it thats why they dont want to invest, second is maybe they dont want to loose their money ,third is maybe because they dont have the knowledge and thoughts about crypto so i guess thats why they are afraid or they dont want to invest in cryptos.
I would not say they are not interested. I would rather say they are just too scared to take some certain risk and that is the major problem a whole lot of them always end up having. The inability to want to take some certain risk in life is what has differentiated those who invested earlier and some who heard about it and decided not to do anything and this is a cycle that would keep on going until we get to the laggard stage of adoption.
Yes, not investing in crypto and especially with bitcoin may turn as a life time mistake too.
Ignorance may lead to big regret too. If we check across this forum, we can see many people are crying for their ignorance by the years 2010 or 2011. I must be one of them.
