Your thinking is flawed.
Essentially you're saying
"BTC hits 100K when big money joins in on the speculation"

You're also assuming big money isn't already in the game either through subsidiaries or under pseudo entities.

Big money doesn't even play the share market like that. They generate new wealth by investments into development that then create new economies and industries. Which then generate wealth over 20, 30, 99 year periods.

Speculation is a fools game.
Big money sees money as a worker.
And just like hiring a worker you don't hire someone on how much bullshit they talked in interview. Merit, ability, skills, qualifications are the criteria.

That's why BTC has a long road.
It still doesn't have real use.
What that will be no one truly knows.
That's why it's wrong to compare it to gold.
Gold has real world use in technology which guarantees that humans won't suddenly stop seeing it as valuable.
