Apart from the name of the site which contains diceGame does the site provide gambling games for the member of the community and even if it does your price of $1250 is too high and many will not be able to participate in the activities of the site due to this high amount in the deposits requirements. And if it does not provide games then you should move this to the appropriate section in the forum.
It is only a domain name which is available for sale and no site is currently build on it. The domain name is indeed very special and attractive one, and anyone who is willing to start his new gambling site can afford to spend such amount.
