Man that's not right to do, you are promoting your service in yolodice's thread and also are taking chance over them. Will you be satisfied if yolodice owner comes in your ANN thread and writes: bitdice is new, bad, slow and etc so move on yolodice, we are in business for years and are better than them
You won't like such proposal, yeah? So respect these guys too.

Btw yolodice, why did you decide to stop investment option? Because your site was among most top gambling websites for investment. If you have grown so much that you no longer need investments that's amazing but still, why? Because even bigger websites doubt whether open investment option or not (fairness is problem usually).
