How much does it cost to build and maintain a website like primedice (for example)?
Hosting,programming,design and advertising costs?
I have an idea about a brand new bitcoin gambling game which will be completely different than the dice sites,
but i don`t know from where to start.
I don`t know if this is the right place to ask,but can anyone answer?
You need a big balance when you are planning to create a gambling website ofcourse you need to pay your programmer designer but if you can do this alone then you need is capital starting approximately of 20bitcoin is enough to run a gambling website.
20btc is not enough to run a gambling site imho, first you need to pay for the script/code, design, domain, your devs, promotions and many other thing. Even if you say that the 20btc is for the bankroll only then I think your site will not get enough players. Usually max winning on single bet is only a little % of your total bankroll, you wont give max winning on single bet = your total bankroll. The problem is that when you have low max winning amount on single bet then big players wont come on your site, perhaps only dust players will play on your site. This condition is not good for your site definetely.
