The site is beyond extremely vulnerable and buggy. 
I do not think so. The base script is buggy. But all should be fixed...
Yep, atm most of the obvious bugs fixed.
By the way, I had requested around 0.9BTC withdrawal yesterday he he. Nothing came through.
Wow, you won a great amount from this coindice script site
but too bad you do not received your winning yet. Hope you'll get your withdrawal soon. Anyway, how many btc you deposit to start betting and won that 0.9BTC?
