Real life dice.
So players will know for sure no one play around with the code or able to hack it. In digital world everything can be hacked, broken and taken. And i believe for professionals it's going to be vnot hard to brake into my web server and see what is going on.

But if the dice machine will do by real dice, it's gonna be very hard to hack it.

I think about it later. May be would be good idea to open non profit company, so people see that the capital will not go to a pocket of rich guy. I'm sure there are ways to lock the funds.
