Trading is just a secondary source of income.
It can be an actual job for those professionals who have been living with the market.
Your job should be still the primary source of income because trading is too risky. You don't know if you can gain profit because of market volatility and also if the coins you choose to trade is good and can give you luck to earn profit.
This should be the norm, for those that are doing part-time trading. There's no need for them to quit their jobs because they can do two things at the same time. They can treat trading as a side hustle while keeping going with their main jobs. Having two or more sources of income nowadays is the wisest thing to do and can help to defeat inflation and keep up with the increase in the price of goods.
