In the throes of the pandemic, I had made a bunch of money from betting on death. So I decided to pay two people to sit in on a Twitter group chat and correct us on economics.
Structurally speaking it's pretty simple: you give them $1000 or whatever to sit in and answer questions whenever they want, talk whenever they want. And then when they feel like their retainer's been burned through, they message you and say "I'm done!".
