Did you read the OP? The prize is for closest prediction, not for the precise one.
I would like to award a winning price of 0.125BTC to the person that gets me the closest price of BTC at April 1st exactly measured at 22.00h CET]
Besides, what "next round" are you talking about? OP didn't state anything about a "next round"...
I read the first message and express my thoughts about it. Is it ok for you?

Speaking about the next round, I meant that if the prize is not won, then OP can make another game or keep the prize for himself. In any case, this is his decision, I am only interested in his opinion.
