I think that even regulation can’t protect anyone from scam. So, first of all, I would check trusted forums and ask people who tried their services, then I would try myself to get the experience of how the broker works. If there is no issue in withdrawals, and customer support is efficient, the broker responds in time, I would trust them. I’ve tried FXpro, but didn’t like it much. I’ve been using Octafx for quite some time, so far it’s been good.
