Thank you a lot, but it is not what I'm looking for. The reason why I could earn money on btc-e betting was the fact that I receive the money which the opposite side lost. All sites you were presented has binary options where I can earn 50% or even 98% if I bet correctly, but it is still the money from the market. I'm sure I can't win with the market (if I can this market shouldn't exist), so sooner or later I will lose.
Do you know any site where I can win as much as opposite side lose? Eventually, it doesn't have to be Bitcoin (I know a bit a dynamic of Bitcoin price, but maybe I can apply my strategy elsewhere).
#Edit
Maybe this kind of binary options (or not?) has some particular name?
