This is not going to happen because it is just high of a price maybe over 50 years it will be possible but not now. It is way to soon for us to talk about millions.
Yeah I agree this is just not happening the price is just way to high. That means that the Bitcoin has to be extremely rare and that almost nobody is going to have it.
That is a lot of money and that can be nice because if it will rise reach that high value than there will be also a lot of people that is going to make profit and that is nice.
The only thing is that you cant change what the value will be and that is the problem of the Bitcoin.
