What is the advantage of a perp versus a series of binary markets? It seems like the perp is trickier to set up. Is the perp interpretable as a forecast? For time-series forecasts, people often care about the full distribution of outcomes, but you can't represent a full distribution with a single number.
I tried something similar years ago because I thought it'd be fun to encourage more API traders:

but it resulted in more compulsive manual trading and less botting than I hoped 😔
The loans still don't work properly, perhaps it is wiser to focus on not building new things for a while: https://manifold.markets/post/i-believe-my-total-loan-is-calculat
@xjp you could bring it back to predictions by making a perp of the polymarket odds on a question /s
@xjp If the perp is on something like "unemployment rate" or "measles cases" then it's an "actual prediction". Doesn't have to be about a financial underlying.
@EvanDaniel And it’s not like there aren’t already dozens of “Bitcoin up/down this week” markets that are more financial than prediction.
