Pretty sure they are not an active project anymore.
You might as well look for alternatives instead of wasting energy on them.
In regards to the max bet, they probably pulled out funds from the site since it's an abandoned project so there isn't much to be said there.
They are not active in this forum but they are still active in social media (blog, twitter, instagram). I have no idea why they leave this ANN thread too long time without update. It seems that they have given up to promote the project in this forum although they started it well in the past with signature campaign but unfortunately they had no promotion at all. I cant say it is an abandoned project but I would say they have lack of time or lack of man power to be active in this forum.
It is possible that they promote it in other forum or other platform not because they have cryptocurrency doesn't mean that this forum is the only way to promote it, I see some successful gambling sites that only offers cryptocurrency and established a few years back but didn't promote or doesn't have an ANN thread here in the Bitcointalk.
Looking at the chat, they currently have less than 15 people and based from the previous bet they don't have that active players but they are still providing their service.
