More I read, more I see that trading in a long term is not profitable.
I don’t understand what you mean by trading is not profitable in the long term. If trading is not profitable in the long term, then most traders will have given up already. I know some people who have been trading for years, and they have been making money from trading, some of them even depend on trading for survival. I know there are some times when you won’t really be making money from trading, but there are some times when things will change around, so I won’t say trading is not profitable in the long term.
So, I wonder are there any profitable traders that make money on the market constantly and sustain decent lifestyle? I am not looking for big money, let's say 2k or 3k per month would be enough.
There are some traders that depend on trading alone, and they are leaving a decent lifestyle just as you said. You said you are looking for big money, if people like you decide to go into trading, you might end up losing almost all you have because you are desperate and looking for a big amount, you don’t want to grow gradually.
If you want to make 2k or 3k, it’s really possible, but depending on the amount that you are trading with, you can’t be trading with a little amount, and you will be expecting that amount of money.
