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.
Bitcoin prices are unstable because business people who use bitcoin are different from different countries, because in each country these different rules make traffickers uncertain. maybe the legal certainty and status of bitcoin in all countries should be the same if you want bitcoin to become a global currency.
