I feel that it would be better if you post the pictures of the emails that you sent to them as a proof.
Why did you send them such large amounts of btc without consulting/asking anyone if the site was legit or not?
I had been betting with them for a month or two and had cashed in and out several times. sometimes more than this. I had that much on there because I had it in play. After having a big day, I cashed out, in an effort to only leave what I needed to play with on the site. I have a friend who's a bigger player as well and sincerely vouched for them. Looks like he was wrong...
he was wrong, MAYBE!
I just feel that you still dont have any proofs against them.
You are a newbie, and without proof your accusationd wont get attention.
