if Bitcoin hit $1,000,000: i will buy mining device,i dont care how expensive it was.
if Bitcoin hit  $1,000 again: i will start store it,and not trade it for long time,i think its a good time to invest or keep for long time.
if Bitcoin stayed where it was: i will keep collect bitcoin as much as i can.
if Bitcoin became worthless, or a few cents: i dont know,maybe stop looking for bitcoin or trade it.

And which of these do you think is most probable?
the most probable is the second choice maybe,but i'm not sure about that.
