You can make alot of money with a Bitcoin gambling site. TONS of money but you need experience, capital, patience, and creativity.
You can't open up another dice site, there are way too many of them out there. You need a special creative idea and you will make TONS of money.
agreed if you get an amazing idea, you can turn into one of the biggest gambling sites out there. all u would need is an idea that seperates your site from the rest, only one that comes to mind is something like a bitcoin lottery system
I don't think bitcoiners like lotteries much though; there have been some lotteries sites in the past but they never became popular. What you need is a completely original concept, like bustabit.com.
