Gamble is a place wich bitcoin had reached and has a lot coins invested, starting a new project will make you to compete with others in the begining, eve the return might be good, you will need to take care at the service you will provide, and improve along the time your script as well make more options to play live. I do believe gamble still a very atractive area to invest, but you will need dedication into it.
But his investment is not enough to make good gambling site,if someone want to be own a good gambling site then he have to offer high prizes which attracts more people towards your site to gamble.If someone want to have good profit from gambling site then then he needs to attracts more gambler to his site.So its gonna need some good investment to open a gambling site with good profits.
Yes you are right my budget is not enough to start gambling site but as you read above i already build script so i want to sell it now.
I will save money and come back with new project. With good budget
