It seems like you've used bitcointalk earlier.
Do you have an original account on these forums?
Yeah come up here with your original old account, hope its not red Do you have an original account on these forums?
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.
2 BTC is just about $13,500 right now and previously when I started on the forum and want to create my own gambling site (just in my head and did research without any sort of action to it), I estimated before that you need at least $20,000 to have someone create a good gambling script and site. Not sure if it is still applicable today, but that is what I found out before. This is also not including the initial bankroll of the site, and based from my old research again, you will need at least 10 BTC to operate a site with a decent max winning. I believe usually gambling site will offer as much as 1% of the house bank roll (taking into consideration the kelly criterion), so 1% would give a max win of 0.1 BTC.
The thing about this, if it is based like the idea of the litecoin.win lottery, you do not lose your bankroll. It is deposit driven. You cannot be part of the lottery with what you dont have. The max winning would be based on how many deposits would be made. One method of losing bank profits would be faucet, but that isnt always part of a gambling site.
OP, I wish you luck.
