Honestly i always seen this site when searching gambling casino related in bitcoin.. but i never play in that site because i think its risky. because never seen or official thread here in bitcoin forum..
So i think you scam with that site. but i was thinking that why that site still alive for a long time and until now they are still alive..
13 days its too long time that we can not consider it as scam.. if they are not responding i think there are only one people who are managing with that site use only for scamming purposes.. so better to stay away next time if the site is not well known..
Apparently yes, maybe the developer is only one person that was managing the whole site or for what you have said scam purpose. When i was also browsing online casinos, it responded different sites which i clicked 1 by 1 to see what's inside and what does it gives me.
For my own opinion only guys please don't be mad at me, mostly the sites with an io on its domain are risky, its because based on my experience most of the times the site where i registered and then they called scam, most of them have an io domain. P.S don't be mad at me maybe i'm wrong but that's just my opinion sorry in advance.
