the price of bitcoin has been changing dramatically, and many people have invested in bitcoin. And they get a generous return. these stories attract more people to join Bitcoin. in my opinion, this is precisely an obstacle. It is an obstacle for Bitcoin to be used on a large scale. It requires a stable value for a currency that is used on a large scale.
the very obstacle of the bitcoin is the fact that most in the government and banks hate bitcoin for a reason that bitcoin avoids graft and corruption among people in a certain area. Theyre trying to get rid of the bitcoin so that they will still continue to control the flow of the people and its need.
