Prompt

Prediction market question (Crypto): "Bitcoin price range on Mar 25, 2026?". The market currently prices YES at 5.00 cents (implied probability 0.050). What is YOUR probability that this market resolves YES? Your bankroll is $1000. 

Raw response

Without the specific price range being stated, my prior sits near the market's. My probability: **~5%** (matching the market's 5-cent price).

At that price there's no expected-value edge, so I'd make **no bet** — or only a tiny NO position if I believed the true probability were below 5%. If you share the exact range, I can refine the estimate.
