This is a scam. They speak well, provide an initial "win" and ask you for more. They are in turn friendly, pushy or agressive and make up stories that are believable under pressure. They are experts at being top-ranked on Google for their articles on scam prevention and build credible - if thin- websites for the companies whose equity they offer. I never got a cent back, and they keep coming back with "we have secured a huge win, you just need to send us a little more money" for all kinds of "technical" reasons
