I don't advise people with no form of job for a reliable income source to in the main time avoid trading if they can because they can't survive it having to depend completely on trading to make earns meet. You would always be be vulnerable to emotions because you wouldn't want to lose your only funds when you don't have it knowing where another funds can come from. There's no how you wouldn't lose in trading irrespective of your expertise or many years of experience but you would do better when you have other means of income not depending only on trading as that would always fuel your emotions when trading.
The source of income is where the money for the investment is going to come from. This shows how important it is to have a source of income before thinking about trading because there is no way that everything can be balanced when you don't have an inflow of money. This shows how important it's going to be to have a source of income, and even if the most important thing is the capital, the most important thing is going to be the upkeep. Because when you don't have a source of income or even emergency funds, how do you keep up with everything that is going on? because you cannot enjoy your trading without having money.
