To determine the winner of Criptan’s monthly no-loss lottery, on the last day of each month we take the hash of the last validated Bitcoin block in UTC time. This hash is converted into a decimal number and then the modulo 9999 is applied, resulting in a value between 0 and 9999.
That number becomes the winning lottery ticket number. All users who hold a ticket with the winning number will receive the prize in the corresponding asset.
