You have devised an ingenious backdoor hack into Twitter that will grant you complete (yet temporary) access to all Twitter accounts.
"How can we make, like, a gazillion dollars off of this?" you ask your co-conspirators.
You sigh, rolling your eyes.
"That's stupid, Keith," you reply (correctly, I might add!). "Think much bigger. We'll have immense, God-like power over the internet!"
Tanking the markets is too obvious, but pumping them, well, that's just modern politics!
So you start buying up short-dated call options on airlines and cruises.
Now, for the tweets...
Bill Gates: "We will have a vaccine in August!"
Federal Reserve: "We will begin buying equity ETFs to support market functioning."
Slowly, you exit the positions, capturing a massive profit for your organization.
"Now this is the life!" you say, lounging on your new yacht. "Bitcoin scam?! Lol."
