Pretty much all estimates in this topic are a joke :X
- $200 - $400 to develop a gambling site? "
the coding can be done by anybody and it is easy"? Lmao. If you want to be hacked or scammed, that sounds right. But if you want a trusted and good developer, you can add some zeros to that amount and be surprised how difficult getting such developer is.
- $6 a month for a VPS? Can be... (my site easily runs on such VPS) but you can't expect to process millions of bets a day on that
The bigger sites generally do pay hundreds of dollars a month for proper servers.
- PD earns 100 bitcoins a day?
It's actually easy to have a theoretical estimation of profits. Just look at my site. HE * wagered, easy. Variance can be more sick than you think though.
In addition people generally overestimate their genius ideas, no offense. Perhaps it doesn't exist yet because people don't care for it. And altho unique ideas can be awesome (like bustabit), sometimes people are hesitant to try something new.
Actually there are some unique games that I like, for example 64blocks.com - and it's even properly developed / good UI / etc. Still almost no traffic/players. Good unique idea, properly developed, trusted owner (Dabs), .... still no players. Just put in some "marketing" and "SEO" is also a lot harder than you think
Overall: people highly overestimate how easy it is to get a gambling site running with a decent amount of players.
