I didn't know if this is not against the bustbit and bustadice gambling owner or something broke their rules.
Yep right, the price on that scrip is quite high and we don't know what will happen to our account once become busted by the owner.
Maybe bustabit and bustadice staff will have a comment regarding this.
I don't think it is breaking any bustabit/bustdice rules as it is just a script where OP put his strategy on betting. There are many other people tried to sell similar script on various websites too but most of them failed to get any buyers because we all know that there is no scripts that works to make us win in gambling.
Looking at his account's stats which has 0.6btc profit while he has just registered few days ago. I think it is just another newbie who has just started gambling and win some money then think that the strategy will always work. The title says 0.6btc per hour, if it does really work then he do not even need to sell the script for 1btc while he can make 0.6btc*24 = 14.4btc per day with the script.
Even worst, he is offering refund while he did not even use escrow here. 1btc is a lot of money, offering refund for this amount then he should use escrow otherwise there will be no refund (high likely).
