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.
It is an obstacle if you let it become one, there are many people that have been here for a long time and they do not really care at all about the fiat price of bitcoin, and people will have learn to think in that way as well, you need to stop caring so much about the price of bitcoin in fiat and just concentrate on using your bitcoin whenever is convenient for you just like you would use your fiat.
if in my opinion, the obstacle of bitcoin is the frequent ups and downs of market prices that are relatively fast and cannot be known. and many ganv campaigns that don't get maximum results. in addition there are also the most pathetic, namely the arrival of hackers.
