Gulf Brokers is a fraud that targets novice investors. They will ask you to make a small initial investment and then show you minimal profit to persuade you to make a larger one. Once they realise you won’t be making any further investments, they’ll present all of your trades as losses and exorbitant swap fees. Every time you want to withdraw money, they will tell you that you have less margin money and should invest more to earn more.
Their advisors are taught in such a way that they will push you to make more investments, which will ultimately result in your total financial loss. I lost $30,000 because of them, so steer clear.
