Hi. I'm looking for the same thing. I started topics here https://bitcointalk.org/index.php?topic=2074348.0 and here http://forum.binaryoptions.net/discussion/4881/win-as-much-as-opposite-side-lose/p1?new=1

I'm also looking for the site which works like btc-e (you receive loosers money) and it doesn't have to be Bitcoin. Only thing I found is a young site https://btcbet.cc/

If you find some other site, please write me here or by private message.
