2 years ago I registered for their virtual trading and I was required to enter my cell phone number. Within a month or so, everyday from Monday to Friday I would get opportunist telemarketers calling me twice a day promoting their $#*!ty forex trading courses. Regardless of how I rejected them, they would still continue calling. This went on for months. Eventually when they knew I wasn't interested, my number was sold to other telemarketing companies and everyday I would get robocalls that hanged up when I answered my phone.
Legacyfx is a crooked broker where they sell your mobile numbers to telemarketing companies and they in turn sell your number to other telemarketers. Don't have anything to do with them and don't give your mobile number to them, give a fake one if you have to. This was my actual experience, I am warning others so that the same won't happen to them and I am not doing this out of malice.
