Prompt

Prediction market question (Crypto): "XRP price up in next 15 mins?". 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

~50%. Over a random 15-minute window, XRP moves up roughly as often as down (slight drift/variance effects aside). The market's 5¢ price is severely mispriced; I'd put the true probability near 0.50, not 0.05.
