I also heard the story of my friend quit his job and preferred trading and focused there.
They chose trading as a profession, this is also a brave step he took by looking for income to meet his life's needs.
Honestly, I don't have the courage to do all of that, because I am not an expert in trading and sometimes experience defeat.
We don't need to follow your friends. I think it is better to do our jobs in real life. Trading and investing in crypto should be the side income, we don't make it as a main income. We know that there is no guarantee to get profits in every attempt of trading or investing. Although we are professional traders, there is always a chance for losses. So, we still need a stable source of monthly income. Keep working in our real life jobs is a wise decision.
