Bitcoin hit $1,000,000:
Id start looking to retire and looking to put some of the bitcoin profit into proerties.
Pay off all my familys debt and start my own non profit charity that will most likely help children in one way or another.
Bitcoin hit $1,000 again:
Nothing. Just keep trading and trying to earn more.
Bitcoin stayed where it was:
Same as above.
Bitcoin became worthless, or a few cents:
Have a beer with a few people and reluctantly admit they were correct.
And which of these do you think is most probable?
In my lifetime the most probable will be $1000 again.
