Everyone has his/her approach towards Cryptocurrency and not all who are involved in it fully understand it not to talk about those who don't know about it entirely
The main reason is simple. People are afraid to lose everything one day. many of them still do not trust "vague" virtual money. Additionally, they see, how the market is going up and down often.
Only few people belongs to the group who do not trust in crypto currency otherwise now everyone is educated and people knows the importance and value of investing in crypto currency, those areas where people are not educated about crypto currency is because they are lack of facilities and lack of knowledge about crypto but in future they also will invest.
