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.
Some of the main obstacles are education and crypto adoption rate. We need to educate people in schools about blockchain technology and increase the adoption rate. More businesses need to accept Bitcoin as a payment method.
