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.
The chance is really low that it will reach that high value and that is because you also can see that it was this year stable for a long time and many people dont like that.
And there will be now a time that it is going to rise for a long time so we can sell it soon.
