I wonder if it's profitable to run a dice gambling site (like dicecoin.io) ? I'm seeing that site has 30,000
BTC wagered in 2 years.. Huge amount.
Certainly it's not easy to operate, promote and maintain by one person but I can absolutely code a site. Is it worth to start?
Have a good night

Remember the amount waged is multiple times the actual btc value since you can wage 1btc 100x or more sometimes 1000x but yes very profitable.
