Resolves yes even for an experiment, or if it's later removed. Implementation doesn't need to be exactly the same, just the core concept.
I currently use multibinary markets for something similar. Example: /Mira/if-mira-trains-a-transformer-model
It kind of looks like one of those normal distributions:
I made many similar markets, and I think "linear interpolation between Fibonacci sequence starting with a custom base" or "linear interpolation between evenly-spaced multiples" could be a really good design. (depending on the quantity being predicted)
@Mira cc: @JamesGrugett in case this gives you ideas for implementation. I think you could give these buckets a custom chart type and the frontend for casual readers of markets would already be really close.
Later, you may also want a custom betting interface and AMM that allows atomic bets on multiple legs, much like how stock brokerages let you buy/sell an entire stock + option leg position in one go.
Logarithmic interpolation is really annoying to bet on without a custom interface, so I don't recommend starting with it.
@Mira Interesting. We have thought of that before, but we were never that enthused by it. Maybe it works pretty well with a few buckets, but is only a small improvement for a lot of buckets.
I think what we didn't like was that it was kind of hard to explain to traders.
