I had also visited the link provided above and it seems like the website looks shady as it shows an image of the sports car. Then again, it is the same kind of tactics that these wicked brokers employed into brainwashing people that binary options is profitable, which in fact is totally opposite. You are betting against the odds and you are getting a negative payout when you win.
A binary option is a financial exotic option in which the payoff is either some fixed monetary amount or nothing at all. The two main types of binary options are the cash-or-nothing binary option and the asset-or-nothing binary option. The former pays some fixed amount of cash if the option expires in-the-money while the latter pays the value of the underlying security. They are also called all-or-nothing options, digital options (more common in forex/interest rate markets), and fixed return options (FROs) (on the American Stock Exchange).
