I think there are a few reasons why people are still not using bitcoins: Not enough awareness is one of them. Even though there are alot of people out there that are usining the cryptocurrency , there are still millions that have not even heard of the crypto currency yet , so i think as times goes by there will be more and more awareness. Also, People are scared of the unknown. If they cant feel it or if know one controls it alot of people re scared of this concept and do not want to be part of a "risky venture". But the main reason is that it hasnt really settled yet. This I think is very important if the bitcoin can keep a steady price for a long time I think more people will begin to trust and use it regularly.
