You were brave to be involved in this trading platform and discussed with the team of "traders". Be brave ! Take a phone and phone to authorities and you will hear the schemes how money goes out from GFBROKER.COM. Do not believe them.
GFBROKER writes about "special computer program":
The more you deposit - the more likely to receive a bonus. The size of the bonus can be from 5% to 300%, depending on the amount of replenishment of the account.The size of the earned bonus is determined by a special computer program by random selection.
Actually it is total nonsense. It is not special computer program but it is human intervention.
