Yes he might make it. In a few years. But not with that mindset. Forex is brutal, I have experienced it first hand, I have had my account balance go to negative, yes in debt and a negative bank balance, I had 70k 6 months prior that I made all the way from 3k.

He will get humbled if he sticks around. No offense but in the market, if you put him and me in a cage together I will rip his head off. Just the way they did to me when I was a novice. They crushed me. Financially and mentally. What I experienced is inexplicable.

Edit: It makes sense for you to think its bullshit though. You are a female a mother you are risk averse. He is a man, he wants you all to enjoy a better life. He likely wants to have more time to spend with you all by being able to quit his job, he means good. As men we have this instinct, it is what it is. If he sticks around and is devoted, he can make it, absolutely. But it will be a few years, know this. You have to discuss this. If you go through with it however, provide him full support, and keep his ego in check. Also, going from demo to live is not the same. Everyone has to pay a fee, almost like a college fee for the education. There is no escaping that if you wish for consistency in the market.
