yeah, we're pretty happy with it atm, though the profit is a bit too much above expectation imo :D unfortunately I don't know any other legit dice site planning to add xmr right now. JD/doog will probably stick with clams, like prc will stick with btc(though they have integrated shapeshift 1 or 2 month ago). my best guess would be to ask alex from bitdice, since bd is already accepting a few alts directly. from an gambling operators perspective accepting xmr should be a no-brainer, biggest hurdle therefor might be that people simply don't know about moneros awesome properties. personaly while I'd like to see xmr grow, I hope that we'll stay the only dice site accepting xmr for some time :D
ps: to improve the visibility of xmr there's going to launch a nice faucet soon, no fixed eta yet, but the plan is to be online before 8/8/15. potential advertisors will be contacted as soon as there is a launch date, but feel free to shoot any question/idea at me you might have.
