Don't you mean Forex?
I'm curious as to what you learned in that class. I wouldn't call it a scam like @DireWolfM14 but it definitely sounds fishy. It could have been one of those useless classes where they don't even know what they are teaching themselves although these things usually take place online.
They might have introduced them to trading lessons on very basic levels portraying them as expert but only sounds like a fake orientation programme where they didn't give you anything useful.There are many fishy things in this case like :
1) He just saw job opportunity board named under Wealth creation and he called on which it was responded by Director himself and asked him to reach the office directly the next day.So he asked $3 and fill out the form so it's like some training programs not providing jobs in first end.
2) How many people were there who paid $3 or more for these useless training programme? So they might have indirectly scammed so many people through this if we see it this way.
3) What was further learning with them or just $3 one day workshop where they said bitcoin is good and nothing more of trading aspects to it?
I think there main motives is to fool people who are in hunt to find new jobs and they make them lucrative offers or will ask them to enroll for courses which have rather less educated instructors or scammers many times so it's total waste of time according to me and don't join them or were you able to find job after that?We are saying it was $3 so he didn't loose anything but if we see broader picture then assume thousand members will have $3k with them and so on the numbers increase.
