because of this fluctuation bitcoin until now has not been able to achieve mass adoption and in my opinion is not suitable for use as a means of payment. although some stores that accept bitcoin as a means of payment in fact only convert to bitcoin to US dollars I think this is still a good step. at least it can be used as a promotional medium that there is currently a new type of currency, cryptocurrency.
And it can affect the price, isn't it?
What is the difference of it from selling your Bitcoin? There is none right? It is the same. And if that continue to happen, then the price might have a dump every now and then. Also, there are a lot of payment methods to use, why would they need Bitcoin to pay if stores does not really accept it? They can use other methods.
