Its impossible for bitcoin to reach $1m price and it would really need huge adoption on bitcoin in able to reach that price. It seems to unrealistic to consider this price though.
Well, I also do not believe in it. although bitcoin prices will be high, but I felt that there would be limits on the price. I think that price becomes the price that is really expensive and can make a person who holds bitcoin when it became rich. I am not sure about this, but nothing is impossible with bitcoin
