I think one of the major problems with people not adopting or accepting cryptocurrencies is a general lack of knowledge surrounding the topic. People are generally fearful of the unknown, and cryptocurrencies are one of the biggest unknowns to the public that has a way of completely distorting their current way of life.
For the general public to become more accepting of cryptos, they will also have to become more aware of what they are. Knowledge and education are cryptocurrencies strongest allies.
Great post my friend, as this furthers knowledge and promotes discussion.
