Hey, if some guy is going to make the very same 8020 prediction as me, then I want to change my first prediction to 8019.
I don't think you're allowed to change your prediction. I guess Bitcasino will determine the winner on a first come, first served basis.
on what time of day do u verify the predictions ? (cause btc price change by the minute)
The winner will be decided based on the Bitcoin opening price listed at Bitstamp on March 13th, 12:00 (GMT).
