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.
Its an obstacle for using as currency but it is making more adoption and imagine if everyone in this world started to use bitcoin the value will get maximised so which causes the price to be more stable than now,just see positive and make the decentralised coin as our payment options.
