The site is too complicated to understand. I couldnt find my way out. 
if you have bitcoin wallet, this is the simplest site in the binary option.
you can see the "HOW TO PLAY" on the upper right corner of site.
1. choose asset that you can predict if the price will go up or down in 60 seconds.
2. copy the address.
3. send the address bitcoin to bet
4. if you win, you will receive 185% reward.
you can select the time frame(1 ~720 minutes).
