Investing always involves the risk of losing, so if someone promises you something that is too good to be true, then it almost certainly is. If any of the well-known binary options brokers (such as 24Option or IQ Option) do not trust a certain robot, then you shouldnt either. The more brokers to choose from, the better for the investor.
This way, you can also take advantage of bonuses, risk-free trades and other possible benefits that are available for new investors. Your investments should always be stored on a separate broker account, and you should be able to turn the robot off whenever you want.
