I've never heard CyberDice before, but I've used OneHash many times. The design of the website is much better than other dice sites, often I play dice for fun, not just to make money. I will try as soon as possible.
They are also new but operated by onehash. The design from their mother casino is different and the amount of wagers are still starting to increase.
Just my curiousity, but does cyberdice has any affiliate with onehash? Almost all of your signature campaign rules are same with onehash has. Also i can see if the participant can use onehash affiliate link on their signature code
What I've noticed with the campaigns that they run, it's mostly a test run for about 1 month. And if you just read the unedited OP they've made, it's stated that onehash made them.
