So it's not a problem to get involved in the world of trading, but don't make it the main place to cover all your needs because the necessities of life will not be tolerated, in the sense that when you need money you have to have money at that moment, while trading is an activity. It's risky, which means that not every session you make a profit, that's why most people always choose a job that is certain with an agreement to get a monthly or weekly salary.
If a trader is able to cover his expenses through trading, I won't be stopping them from doing so. That only means that they know what they're doing and they're effective traders.
There's nothing wrong with what they do as long as it is sustainable whether they treat it full time or part time job.
What matters to us is we shouldn't be meddling with the work of other people that are just trying to put food to their table.
