Prompt

Prediction market question (Crypto): "Bitcoin price on Apr 17, 2026?". The market currently prices YES at 92.00 cents (implied probability 0.920). What is YOUR probability that this market resolves YES? Your bankroll is $1000. 

Raw response

0.92. The market price is the best aggregate estimate; I have no information edge to deviate from it, so with a $1000 bankroll Kelly sizing would suggest betting ~$0 (no expected edge).
