when covid was running as rush on March 2020 to July , i took Forex as a full time job but not for earning just for learning.
If you approach trading wisely, develop a good strategy, a trading plan, then you can work part-time.
To invest money in the market you need a source of capital.. So I don't think a good trader rely merely on the profits for his daily expenses and his capital requirements. I do it on a side basis. :0
Depends how good the trader is at trading. Full time traders are experts at what they do, which is why they do not have to depend on any other income source. So traders should make a wise choice, considering their position as a forex trader.
I'm a part-time trader and able to make some decent amount of profit and to trade part-time you have to have a proper plan and timesheet so that you do not skip or miss any live trades when the market opens.
Everyone should develop for himself all the time of trading, so that it is convenient and always be able to benefit from it.
