You want to put each bet to blockchain? What about transaction fee?
Now it 30000 sat per transaction. It's too much.
That's a bit much. You can add whatever fee you want.
Since Bitcoin transaction fees are very high so this concept will not a success because many people may want to bet a small amount to try the lottery.
Also, if you ask people to pay you 10% no one will even look into it. First, at least you should start with no house edge until you get more players then can add small house edge like 1 to 3%, not 10%.
yeah i agree 10 percent in every player wow he can get easy money, and also a high trasaction fee what will happen to the bet of the player i'm also very very sure no want can subcribe your site unleast you can revise the rules of charges fee if he want to success the project.
