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 adoption is one of the problem of the bitcoins. Many people are still not aware to what is bitcoin and it is the reason why they are still not adopting it. If we keep our spreading our knowledge to other people. I am sure that the people will become interested to patronize it.
