I will bet on weather condition at 14:00, and receive my win or loose at 14:40. Am I right or not ?
No you are wrong on this. You are not betting for the weather condition at 14.00 but you are betting for weather condition at 14.40 and will receive your winning if your bet has atleast 1 confirmation. It will be pretty disadvantage situation for the OP if you are betting on 14.00 because people could abuse this by betting on the last minutes to get a much more accurate data
Hello, you can bet when you like it, but betting will be closed every 3 hours and you can bet up to 40 minutes before the result,
for example:
bet closing in 1 minute:
Result in ~40 minutes
or
bet closing in 2 hours and 30 minutes
Result in ~ 3 hours and 10 minutes
However with the concern raised by TurtleHurricane, The OP has gotten alot more advantages for this game because the site getting data from 40,000 weather station which means that the data is gotten from either one of 40,000 stations or that it will be an average from 40,000 stations which may cause players to lose if there is atleast few station that got their prediction wrong
bravo - very good idea
