I have a great idea,
If someone can make a bitcoin casino which serves a lot of ads and the ads incomes that used to goes to the casino website turns to goes to every player on the website as play-only (non-withdraw) bitcoins so that every new members can play with real bitcoins and if they won, they can withdraw, if they loses, the money still goes to the casino website.
What do you guys think?
This would work if the site were only supported by ad revenue aka not taking bitcoin deposits. As bit777 said no one likes ads. Which means less people spending bitcoins would play at said site. Lastly whenever said gambler earned "points" these points would likely be worth one micro btc or satoshi. With that said if a Admin were to make a site like this it would probably be better to host in alt coins since they are worth less and players could feel more accomplished about earned 1 cent or one coin.
