Yes its true that most pple earn a living from their mentees fees and that's because they don't actually make their living in the market. The fx space has divisions, a lot of the so called big traders do forex business not trading. Making money with trading ain't easy, most times as a swing trader I do have to open positions for days before profit π its a hard earned money.
That said two thing is sure in the market and time do tell:
Pay the market to learn.
Pay to learn from someone who is already multiple times ahead of where u want to be. Its a basic thing "if you want to go fast, go alone but if far go with others"
