I guess Rollbit is not offering a particular type of trading that Binance or any other exchange have. As far as I remember, Rollbit is about to launch a "Binary Options" in their website and is not a Spot or Futures type of market in particular. As I can see, though, launching Binary options on a gambling website is pretty unique and is quite a smart move on their end, so I think none of the current existing gambling site and in the past is currently offering such option.
Just to add, Binary trading is basically 1/0 or YES/NO type of trading at a given period of time. Hence, it is derived from the word Binary that has only 2 options. Personally, it is a hybrid of "Ace Deucey" and "Trading" which of course includes indicators.
Years ago there were some websites that offered binary options, many traders and investors do not really consider binary options as a legitimate way to trade the market and this is because the actual options that you have are very limited, which is why it is called binary options, they consider this to be a form of gambling because they limit what you can do, however if any person is able to guess what the market is going to do in a consistent basis then they are free to try binary options if they want, but in my opinion they will be better off by using their skill in the real markets.
Yes, most reviews I have seen consider binary options purely gambling and like in gambling, most participants lose money and only very few achieve profit on long run. It's quite hard to predict the market fluctuations inside a short period of time, making technical analyzes useless, and the profit margin unstable. It's not like dice where you set the odds as you wish. In binary options if you hit the right result, but with a low margin, the profit will be decreased. It makes the strategies such as martingale risky to be applied. Anyway it's nice to see a gambling site adding binary options on their list. I think it really belongs there.
