Well Ill do this,
Bitcoin hit $1,000,000: Be rich

Do whatever i want.
Bitcoin hit $1,000 again: Ill hold it, maybe invest or gamble.
Bitcoin stayed where it was: Hold it and do what i do right now.
Bitcoin became worthless, or a few cents: Nothing will still keep the btc thinking it cant go any lower and would only go high from now and probably lose interest in btc.
And which of these do you think is most probable?
Maybe the options 2&3 look the most likely outcomes.
