Seems lately there are a few of these trading challenges.
And with so many people trying it, in the end someone will succeed, which does not mean that it is a good system to earn money, because the risk of bankruptcy is very high.
And people are skeptical but the way it works is like this. They usually post the trades live but it doesn’t mean they are trading with real money.
They might get lucky and trade demo and make it to the goal, and then they will usually offer some type of signal service and want money for it. Many will sign up because if they went from $1 to $10K once they can do it again most likely. And that is how the scam typically works.
I would advise anybody to stay away from this. Anyone who knows a little mathematics and finance does not fall for this.
