I believe that the main reason that bitcoin was created was to be able to do payments from one person to another without the banks and secure and fast as possible. Now with the increase of fees and waiting time around 20 minutes bitcoin if far from the main idea which it was created. So many people say that bitcoin is there just as a reference value or to store value like gold does. There are new platforms , faster and low fee and this may replace bitcoin as main payment platform. So Ligthing is comming to solve this issue but answering your question that is not very clear now on what is the purpose of bitcoin.
