that he doesn't believe in this thing at all and it will someday explode.
so i would like to know your respective opinions on this matter and how it will affect bitcoin on the long and short term
These statements have a power to discourage bitcoin users for short term, however, I didn't see any long term effect on bitcoin's price from such comments. JPM CEO Jemie is a powerful person in financial world, so the market reacted to his statement just as envisaged. However, the moment people realized that how false that statement is, the market came back to normal in no time.
I didn't know about the statement of Arabian price, but I can see that the market didn't react at all. No impact on bitcoin price at all. However, I am unable to see any reason behind his statement about bitcoin. banking business is directly affected by bitcoin and hence Jemie's statement was there for a reason. But Arab's business is Oil which doesn't have any co-relation with bitcoin. So that's absurd!
