Personally I have negative experience with binaries. With one of Russian companies. Loss is got significantly more often than profit and I dare say even too much often to be just coincidence even if you get to trade after thorough analysis. I will never be surprised if one day I suddenly discover an obvious evidence that binaries are manipulated. I think they are just casinos that position themselves to be brokers. But I am glad that got my negative experience only with not very great amount. Avoid that stuff.
