2BTC is not much these days and it might not be enough for you to run advertising campaigns and other promotions to have players on early days. Also the lottery model you are talking about is not actually a lottery. Its a copy of busta game and I think you have one unlicensed version which you gonna use here.
Although domain name is perfect...
2B is not much when it comes to the casinos bankroll.
However 2B is very high when it's only for for domain hosting and development costs.
The biggest issue with this idea is that it has been tried and tested in the past and failed unfortunately.
Basically with a low edge dice available there is absolutely no point in doing a lottery.
Most will simply play with a corresponding win percentage and it can be like a regular lottery.
