Welllllll..... you are obviously working for them, since no one else has ever heard of them. Not to mention the fact I can't find a binary broker called EnCapital, only this shady looking investment services website that mentions nothing about binary... what's the deal?
On average, if you only win 50% of your trades, you will be a net loser. YOu have to be at least 54 to 55% correct in your trades to even break even which makes it a minus sum game, just like gambling at the casino. However, unlike gambling at the casino it is possible to SPECULATE markets using binary, that is, make well educated decisions based on market conditions, price action and experience, which will elevate your trades above the break even mark. The down side is that "most" traders will become discouraged before reaching that level.
