When I opened primedice this morning it was written 600 + bets in last 24 hours. How much people win or lose I don't know but for sure site is in big plus when they have been here for years. Rollin is good site, they have a bit less wagerd then prime dice so they earn less.
There is a topic is it profitable to make dice site for gambling. As I understand in the end is important to have as many people there gambling. Sometimes they will win, mostly they will lose. House always win, how much exactly nobody knows.
I gambled on primedice a couple of times, I found out that gambling on dice is not my thing. I couldn't figure out a strategy for myself and lost it all.
Primedice is a good site though, I don't have any complaints about them.
